Microservices Architecture Enabling Scalable Modern Applications


Microservices have emerged as a game-changing architectural style for designing and developing modern software applications. This approach offers numerous advantages, such as –

  1. Scalability
  2. Flexibility
  3. Easier maintenance

This article delves into microservices, exploring their benefits, challenges, and best practices for building robust and efficient systems.

What are Microservices?

Microservices break down an application into loosely coupled, independently deployable services. Each service emphasizes a specific business capability and communicates with other services through lightweight protocols, commonly using HTTP or messaging queues.

This design philosophy promotes modularization, making it easier to understand, develop, and scale complex applications.

Essential Principles for Microservice Architecture Design

The following fundamental principles guide the design of Microservices architecture:

  1. Independent & Autonomous Services: Designed as individual and self-contained units, each Microservice is responsible for specific business functions, allowing them to operate independently.
  2. Scalability: The architecture supports horizontal scaling of services, enabling efficient utilization of resources and ensuring optimal performance during periods of increased demand.
  3. Decentralization: Services in the Microservices architecture are decentralized, meaning each service has its database and communicates with others through lightweight protocols.
  4. Resilient Services: Microservices are resilient, capable of handling failures gracefully without affecting the overall system’s stability.
  5. Real-Time Load Balancing: The architecture incorporates real-time load balancing to evenly distribute incoming requests across multiple instances of a service, preventing any specific component from becoming overloaded.
  6. Availability: High availability is a priority in Microservices design, aiming to reduce downtime and provide uninterrupted service to users.
  7. Continuous Delivery through DevOps Integration: DevOps practices facilitate continuous delivery and seamless deployment of updates to Microservices.
  8. Seamless API Integration and Continuous Monitoring: The architecture emphasizes seamless integration of services through APIs, allowing them to communicate effectively. Continuous monitoring ensures proper tracking of performance metrics to help detect issues promptly.
  9. Isolation from Failures: Each Microservice is isolated from others, minimizing the impact of a failure in one service on the rest of the system.
  10. Auto-Provisioning: Automation is utilized for auto-scaling and provisioning resources based on demand, allowing the system to adapt dynamically to varying workloads.

By using these principles, developers can create a Microservices architecture that is flexible, robust, and capable of meeting the challenges of modern application development and deployment.

Common Design Patterns in Microservices

Microservices architecture employs various design patterns to address different challenges and ensure effective communication and coordination among services. Here are some commonly used design patterns:

  1. Aggregator: The Aggregator pattern gathers data from multiple Microservices and combines it into a single, unified response, providing a comprehensive view to the client.
  2. API Gateway: The API Gateway pattern is a single entry point for clients to interact with the Microservices. It handles client requests, performs authentication, and routes them to the appropriate services.
  3. Chained or Chain of Responsibility: In this pattern, a request passes through a series of handlers or Microservices, each responsible for specific tasks or processing. The output of one service becomes the input of the next, forming a chain.
  4. Asynchronous Messaging: Asynchronous Messaging pattern uses message queues to facilitate communication between Microservices, allowing them to exchange information without direct interaction, leading to better scalability and fault tolerance.
  5. Database or Shared Data: This pattern involves sharing a common database or data store among multiple Microservices. It simplifies data access but requires careful consideration of data ownership and consistency.
  6. Event Sourcing: Stores domain events as the primary source of truth, enabling easy recovery and historical analysis of the system’s state.
  7. Branch: The Branch pattern allows Microservices to offer different versions or extensions of functionality, enabling experimentation or gradual feature rollouts.
  8. Command Query Responsibility Segregator (CQRS): CQRS segregates the read and write operations in a Microservice, using separate models for queries and commands, optimizing data retrieval and modification.
  9. Circuit Breaker: The Circuit Breaker pattern prevents cascading failures by automatically halting requests to a Microservice experiencing issues, thereby preserving system stability.
  10. Decomposition: Decomposition involves breaking down a monolithic application into smaller, more manageable Microservices based on specific business capabilities.

Developers can efficiently design and implement Microservices that exhibit better modularity, scalability, and maintainability, contributing to the overall success of the architecture.

Few Sample Architecture Of Microservices

Advantages of Microservices

  1. Scalability: With microservices, individual components can scale independently based on workload, enabling efficient resource utilization and better performance during high traffic.
  2. Flexibility: The loosely coupled nature of microservices allows developers to update, modify, or replace individual services without impacting the entire application. This agility enables faster development and deployment cycles.
  3. Fault Isolation: Since services can decouple, a failure in one service does not cascade to others, reducing the risk of system-wide crashes and making fault isolation more manageable.
  4. Technology Heterogeneity: Different services can use varied programming languages, frameworks, and databases, allowing teams to select the most suitable technology for each service’s requirements.
  5. Continuous Deployment: Microservices facilitate continuous deployment by enabling the release of individual services independently, ensuring faster and safer rollouts.

Challenges of Microservices

  1. Distributed System Complexity: Managing a distributed system introduces complexities in terms of communication, data consistency, and error handling, which require careful design and planning.
  2. Operational Overhead: Operating multiple services necessitates robust monitoring, logging, and management systems to ensure smooth functioning and quick identification of issues.
  3. Data Management: Maintaining data consistency across multiple services can be challenging, and implementing effective data management strategies becomes crucial.
  4. Service Coordination: As the number of services grows, orchestrating their interactions and maintaining service contracts can become intricate.

Best Practices for Microservices

  1. Design Around Business Capabilities: Structure services based on specific business domains to ensure clear ownership and responsibility for each functionality.
  2. Embrace Automation: Invest in automation for building, testing, deployment, and monitoring to reduce manual efforts and improve efficiency.
  3. Monitor Relentlessly: Implement robust monitoring and alerting systems to identify and address performance bottlenecks and issues proactively.
  4. Plan for Failure: Design services with resilience in mind. Use circuit breakers, retries, and fallback mechanisms to handle failures gracefully.
  5. Secure Communication: Ensure secure communication between services by implementing encryption and authentication mechanisms, which effectively deter unauthorized access.


Microservices have revolutionized modern software application architecting, development, and scaling.

Organizations can achieve greater agility, scalability, and maintainability by breaking down monolithic systems into more minor, manageable services.

However, adopting microservices requires careful planning, coordination, and adherence to best practices to harness their full potential.

With the advantages of microservices and addressing the associated challenges, businesses can build robust and adaptable software architectures that meet the demands of today’s fast-paced digital landscape.

Leveraging The Cloud To Deploy A Winning Enterprise IT Strategy


Organizations require to establish comprehensive enterprise IT strategies to fulfil the overarching business requirements and stay competitive. Information Technology constantly evolves to provide new ways to do business, and the last decade saw the emergence of cloud computing solutions as a powerful technology to drive long-term benefits for an enterprise.

IT infrastructure is a broad field comprising different components such as network and security structure, storage and servers, business applications, operating systems, and databases. Organizations are grappling with key challenges when it comes to scaling up their IT infrastructure.

⦁ Difficulty in keeping the IT team abreast with the latest IT infrastructure advancements and complexity, which subsequently also impacts productivity.
⦁ High expense ratios such as almost about 70% of the IT budget are spent on maintaining current IT infrastructures, and only around 30% of the IT budget is spent on new capabilities.
⦁ Infrastructure security which is a primary concern for all businesses is predicted to face security breaches of 30% of their critical infrastructure by 2025.

In this blog, we’ll explore some critical top-of-the-mind questions for cloud professionals, such as-

⦁ How do I keep pace with the rate of innovation in the evolving and ever-dynamic environment?
⦁ How could IT help me gain a competitive advantage against new competitors?
⦁ What is the best strategy to optimize IT costs? How do I find the perfect balance between fixed and variable IT costs?
⦁ Which cloud consumption models are best suited for my organization’s business model?
⦁ What is the right strategy for cloud adoption? Observe and implement or predict and innovate?
⦁ How to get started with cloud pilots?

Exploring the Potential of Cloud Computing

Cloud computing solutions have been a key enabler for big innovations in enterprises and could provide the answers to the myriad of questions that challenge CIOs today. Cloud computing services enable enterprises to become more agile. Cloud offers better data security, data storage, extra flexibility, enhanced organizational visibility, smoother work processes, more data intelligence, and increased employee collaboration. It optimizes workflows and aids better decision-making while minimizing costs.

Cloud has now moved from merely being an on-demand and grid computing platform and is now tapping into advancements in virtualization, networking, provisioning, and multi-tenant architectures. Cloud services are critical to building leaner and more nimble IT organizations. It gives companies access to innovative capabilities with robust data centers and IT departments.

The first step to designing a cloud strategy is to outline the business goals and the challenges the cloud will be able to resolve. A holistic approach to creating a cloud strategy will help create an adaptable governance framework empowering businesses with the flexibility to handle different implementation demands and risk profiles.

How Does Cloud Create Tangible Business Value for Enterprises?

Cloud computing and digital transformation are integral to modernizing the IT environment. Listed here are the top six cloud value drivers that are transforming the enterprise business strategy:

⦁ Catalyzing business innovation through new applications developed in cost-effective cloud environments.
⦁ Maximizing business responsiveness.
⦁ Reducing total ownership cost and boosting asset utilization.
⦁ Offering an open, flexible, and elastic IT environment.

⦁ Facilitating real-time data streams and information exchange.
⦁ Providing universally accessible resources.

Cloud game-changing value-drivers | Cloud services

Let’s dive deeper into how cloud computing creates tangible value for enterprises.

Reducing operating costs and capital investments

Cloud computing services encompass applications, systems, infrastructures, and other IT requirements. By adopting the cloud, companies can save an average of 15 % on all IT costs. Cost optimization is the main reason why 47% of enterprises have opted for cloud migration.

Cloud services provide natural economies of scale allowing businesses to pay only for what they need. Businesses can achieve cost savings with the cloud as it optimizes both software licenses and hardware or storage purchases both on-premise or within the data center. A cloud strategy allows businesses to reduce upfront costs and shift to an OpEx model.

Pay-for-use models enable businesses to access services on-a-need basis. Cloud lowers IT costs and frees up time to focus on optimization, innovation, and more critical projects. Enterprises could prune their IT operations and allow CSPs to manage all operating responsibilities using cloud solutions that sit higher in the stack.

Access to finer-grained IT services

Cloud eliminates multiple barriers that stand in the way of small enterprises. Small enterprises often don’t have the resources to access sophisticated IT infrastructure and solutions. Cloud allows small enterprises to access IT solutions in small increments depending on their budget and business goals without compromising efficiency and productivity. The biggest advantage of cloud models is that they open up access to flexible solutions that are otherwise economically not feasible. Cloud computing solutions, before, level the playing field for small businesses and allow them to compete with larger enterprises.

Eliminating IT complexity for end users

Cloud can simplify IT systems making it easy for businesses to operate. With the cloud, users don’t have to bother about upgrades, backups, and patches. Cloud providers can handle all these functions so users are ensured of seamless access. Cloud’s open approach architecture paves way for new IT outsourcing models. So far, cloud models primarily catered to large enterprises with large IT requirements and at times had lesser scope to accommodate the IT requirements of smaller enterprises. However, the advent of the cloud has enabled small companies to access quality IT services at affordable rates. Mobility and data security are the two key areas where businesses will benefit from the cloud.

Leveraging the pay-per-use cost structure for cloud IT services

Cloud has transformed IT costs from fixed costs to variable costs. That means enterprises with varying IT requirements can safely rely on the cloud. Enterprises may have varying storage needs and the pay-per-use cost structure is highly beneficial for such enterprises. Large enterprises can expand or contract capacity for select applications if they already have existing IT infrastructure.

As updates are included in the cost, enterprises don’t have to deal with obsolescence. An organization’s overall IT requirements determine to what extent the IT costs will transform into a variable cost structure. The cloud allows businesses to trade fixed expenses like data centers and physical servers for variable expenses and only pay for IT services as they are used. The variable expenses are much lower compared to the capital investment model.

Standardizing applications, infrastructure, and processes

Digital transformation and cloud adoption are foundational to standardizing applications, infrastructure, and processes. A ‘lift and shift’ approach where legacy applications are simply moved to the cloud will not yield benefits. The dynamic features of the cloud help replace current processes with industry best practices to eliminate process bottlenecks and high costs. Standardization helps tame the complexity of modern infrastructures and their potential pitfalls. Cloud-driven solutions can also replace non-core applications that greatly improve business processes and provide the level of transparency and standardization that modern companies are looking for. Cloud-based data standardization is driving digital transformation across business functions in multiple industries. Cloud makes applications more scalable and interoperable and opens access to a scalable set of secured solutions.

Cloud computing for organizations in emerging markets

Organizations in emerging markets have been quick to realize the benefits of cloud computing. Cloud computing represents a paradigm shift; it has transitioned from ‘computing as a product’ to ‘computing as a service.’ Organizations in emerging markets get an opportunity to leapfrog their counterparts in developed countries with cloud adoption. Rather than buying hardware and software and investing in maintenance and configuration, cloud computing services enable companies to use applications and computing infrastructures in the cloud-as-a-service (CaaS).

Cloud piloting

Capturing the benefits of cloud adoption requires a holistic approach. Even companies that once preferred to have their own IT infrastructure and systems are shifting to the cloud to leverage its scalability and higher-order functionality. Pilots help determine the impact of cloud adoption on core IT operations as well as the business model. An initial assessment of the impact of the cloud is integral to creating a sound cloud strategy.

Businesses that adopt a cloud-first approach will witness a significant impact on their products/services and delivery and sales models. Pilots should be initiated depending on whether cloud adoption will impact the application layer or infrastructure layer in your enterprise. A decrease in time to market for new applications is a crucial benefit of cloud adoption.

How to Get Started with Cloud Computing?

While some enterprises have adopted a hybrid approach, others have moved to a private or public cloud solution. Companies have embraced the cloud in one way or another as a part of their digital transformation journey. Moving to the cloud will enable businesses to focus on more strategic problems like accurately forecasting through good data management and automating repetitive business processes.

Though the cloud is no longer in its infancy, many enterprises are still faced with challenges when it comes to starting their cloud computing journey. Conducting a pilot is the perfect way to start the cloud computing journey. You can choose from a variety of products and services to conduct a cloud pilot.

Conducting a Successful Pilot? Following are the Key Steps to Follow:

Step 1: Assess your business need

Define the business imperatives and determine key areas where the business needs to integrate with the cloud. Assess the triggers for cloud transformation. If you want to reduce costs or accelerate digital innovation, you will need to conduct pilots accordingly. Cost reduction and performance improvement of business applications will require you to conduct a SaaS pilot.

Step 2: Evaluate options

Take the SaaS pilot as an example. You would have multiple providers to choose from, all with capabilities and experiences that match your requirements. You must evaluate the level of cloud adoption in your industry and assess how various Saas providers match up to that. The evaluation should support the logic used to determine the right type of pilot for your business.

Step 3: Launch the pilot

The final step is to launch the pilot and collect data that will give insights into the road ahead in your cloud computing journey. The data collected at this stage will form the basis for your future cloud strategies and serve as the cornerstone for creating a robust, data-driven, and actionable cloud adoption blueprint for your organization. Once you’ve done a pilot, you can move to the next phase of your cloud journey.

Cloud has undoubtedly had a massive impact on the enterprise-technology ecosystem. In 2020, 81% of technology decision-makers said their company already made use of at least one cloud application or relied on some cloud infrastructure. The two key aspects of cloud computing, as with any other technology, are cost reduction and risk mitigation. A well-architected cloud environment is integral to reaping the full benefits of cloud technology. Legacy applications pose risks such as security issues to organizations. A sound cloud strategy takes into consideration cost recovery and risk mitigation. Businesses must prioritize investments in cloud transformation after performing a thorough assessment of their existing business models.

The cloud transformation journey for each organization is unique. The cloud strategy depends on multiple factors such as risk appetite, scope, existing technology stack, and budget. Even organizations planning to start small should consider cloud adoption as a vital part of their IT enterprise strategy to accelerate digital transformation and stay ahead of the competitive curve.

Open Banking: Carving New Pathways Through Digital Transformation

The global enthusiasm around open banking has been soaring high as it sets a pace for the industry 4.0 to transform systematically through digital change and disruptive innovation. The transformation is just not limited to how banks would eventually evolve, but primarily aims at introducing value-added benefits for the customers and building a secure value chain.

Let’s dive into the concepts of open banking and understand the drivers that are fueling this innovation, the challenges and threats it poses, and how banks and other players plan to transform and develop new revenue models through the open banking channel.

What is Open Banking?

Open banking, also known as ‘open bank data’, is a platform-based approach that is destined to stay and evolve. It is a banking practice that provides third-party financial service providers with open access to consumer banking, transaction, and other financial data. The consumer data is captured from banks and non-bank financial institutions through the use of application programming interfaces (APIs).

The Evolution of Open Banking

Financial institutions, since their inception, have been collecting precious information about their customers and their transactions, with little or no knowledge of how to harness this data to its effective value.

Today, financial institutions leverage the data to narrow down customers’ preferred choices and this includes everything from their favorite restaurant or coffee shop to which shops they buy most of their shirts. Financial institutions also capture non-consumer data known as meta-data from cash machines, branch locations, number of loans, mortgages, different account types, and volume of transactions. With all this data captured in heaps, it becomes easier to analyze customer preferences and suggest relevant products and services that could be of their interest.

Due to an increase of around 50% in access to additional customer data and an approximate 70% decrease in time to market, open banking is without a doubt garnering the most interest within the fintech industry.

If we think about the short term alone, open banking is expected to increase financial institutions’ revenue by at least 20%-30%. These numbers are jolting the fintech industry towards renewed innovation of banking and payment services, making it easier and more accessible for customers.

Conventional Banking Vs Open Banking

Driving Forces Behind Open Banking Adoption

Due to the global pandemic, the past few years have been quite challenging for financial institutions. This situation also built opportunities to innovate and introduce solutions that had the potential to drive a positive impact on their future profit goals.

1. Changing Customer Behavior and Expectation

Newer and older generations such as Generation Z or Generation Alpha, have distinctly different behavior and requirements, pushing financial institutions to rethink their process for creating and selling their products and services to them.

For instance, a bank has to consider whether the product or service they offer satisfies the customers’ needs or not. The shift from a product-centric approach to a customer-centric approach is important. This mindset has caused financial institutions to rethink and upgrade their offerings by keeping customer experience at the core of the product development process. Moreover, these days customers enjoy an unprecedented level of market transparency, and their satisfaction level goes beyond accepting a limited choice of products offered by their main bank. With exposure to frictionless user experiences, they can now quickly differentiate between a good and bad CX, and are now not in a state to accept anything mediocre.

2. Technology Fueled Innovation

Radical innovation in digital technology, exponential growth in smart devices, and the shift to instant payments, have opened new opportunities within financial services. Spurred on by the growth of APIs, they have now become the foundation of the entire open banking system. The integration of cloud-based platforms has further enhanced the agility, flexibility, and scalability of financial institutions’ abilities. Additionally, advancements in exponential technologies such as AI, real-time analytics, machine learning, and blockchain have further improved processes, services, and products across all levels.

3. Evolving Regulations

Governments across the globe have been ushered into taking a proactive approach to the “democratization” of financial products and services. Nudged on by EBA in the EU after the adoption of PSD2 in 2015, formally ushers in the concept of open banking. Regulation breeds innovations and naming the concept as ‘open’ denotes its explicit policy goal that the concept must be considered and adopted across all financial institutions. Compelling banks to make their proprietary data available to third-party providers.

4. Increased Competition

A large number of organizations – backed by technology giants like GAFA (Google, Amazon, Facebook, and Apple) – have entered the financial services market. These fintech organizations are providing quicker payment solutions, with seamless integration of cards, e-wallets, and other payment options fueling competition with the banks. As a matter of fact, these organizations are more ready and actively preparing to offer their services within the open banking ecosystem, further ramping up competition with banking institutions.

How Open Banking Will Take the Front Seat in the Financial Ecosystem

Currently, the ‘open revolution’ market consists of both: established financial institutions and new players. The range of applications begins from a ‘minimum approach’ that permits third-party access using APIs for the purpose of sharing selective data to ‘maximum implementation’ facilitates the integration of diverse functionalities by leveraging the Banking-as-a-Service platform (BaaS).

‘True’ open banking goes beyond the exchange of information and impacts the core elements of financial service providers including established processes and legacy core banking systems. They possess tremendous potential and allow players with varying needs to connect, therefore benefiting different bank types and the entire financial industry as a whole. The customers too benefit as they gain access to a wider range of products at a single touchpoint rather than reaching out to multiple service providers.

For some product categories like mutual funds, mortgage loans, or structured products, incorporating third-party products has been a common practice for banks for many decades thus far. This concept has also been applied to deposits, one of the most widely used products by bank customers and a major source of funding for banks.

Flexibility and a More Complex Competitive Environment

Banking Now vs Future

Driving Value for Stakeholders

The open banking ecosystem is geared toward a holistic benefit approach that considers its customers as well as the industry stakeholders. Outlined below are a few instances of value created by the innovation open banking platforms have adopted.

1. Flawless User Experience

Due to the potential convergence of open banking and artificial intelligence, user experience is undergoing an incredible digital transformation. The continuous influx of data across several sources enables service providers to determine the exact customer sentiments and requirements resulting in highly personalized financial offerings. Several tedious procedures are also expected to become simplified and automated. Through banking APIs, fintech firms offer users the opportunity to improve their financial lives through financial planning capabilities and insights based on their own data. Essentially, opening banking enables banks and similar financial institutions to create a unique financial profile for each customer according to their financial data. Allowing them to predict their consumption patterns and behavior to execute product customization more efficiently.

2. Real-Time Payments Facilitating Easier Treasury and Cash Management for SMEs

Open banking facilitates near-instantaneous payments, as third-party providers can bundle all payments within a single digital interface. Typically, SMEs don’t have their own treasury departments, unlike their bigger counterparts. Real-Time Payment (RTP) transforms treasury management services, driving value for SMEs through increased visibility of their cash flows and liquidity positions. RTP also speeds up the Peer to Peer (P2P) payments, bill payments, and e-commerce payments ecosystem.

3. Data Sharing Prompting Product Innovation and Financial Freedom

Open banking ensures that banks only share their customer’ data with authorized third parties. This will lead to the development of better financial products as organizations can leverage the data to extract customer insights and subsequently become more innovative and customer-centric.

4. APIs Enhancing Cross-Selling and Cost Optimization Opportunities

Open Banking offers banks the opportunity to blend product and service features offered by third-party providers to create their own offerings using APIs as a plug-and-play model. Tying together such readily available services from third-party providers and vice versa, banks can quickly improve customer service, boost customer loyalty, create new revenue streams, and decrease bank operating costs. Moreover, banks can mitigate the risk and expenses of experimenting with newer products simply by adopting the plug-and-play model of integrating APIs of third parties along with their core products on their digital platform.

5. Data Transparency

The need for building transparency might seem obvious, but each platform and disruptive technology comes with its own story and unique set of challenges. For open banking platforms, these challenges have given credence to the regulatory and similar competent authorities to focus on the need for building transparency by ensuring that the customers’ interests and rights are at the heart of all focus areas.

The potential impact of open financial data on GDP and how it varies according to different regions.

Potential GDP impact

Risks and Challenges Banks Need to Consider to Succeed in the Open Banking Ecosystem

Although the advent of open banking has been largely positive for the financial sector, it has also opened up several new challenges and risks for banking institutions. Many of these will have far-reaching consequences for their business prospects, possibly reaching the point of existential crisis.

Let’s consider some of the key points:

1. Rise of New Competition

Leading banks are now being challenged by pure digital entities like GAFA. These fintech are attracting customers in heaps by providing unbundled, innovative, and engaging financial products and services. Meanwhile, many leading banks are still relying upon legacy systems, and if the threat is not addressed soon, will risk the prospect of losing their market share, greater customer churn, and increased pressure on margins.

2. Data Security

Sharing financial data through APIs to third-party providers bears the inherent risk of data security and breaches. The absence of industry-wide technical standards and data sharing protocols might leave operating processes vulnerable to security breaches and fraudulent activities. Using complicated interconnections of data access, banks need to invest heavily in security initiatives and risk mitigation, which often heavily impacts their bottom line. At the same time, banks cannot afford to miss out on the potential revenue generated by these data streams within the open banking ecosystem.

3. Risk of Commoditization

Due to open APIs, leading banks will face the risk of being commoditized. Reason: The elimination of several existing barriers to switching accounts and shopping around for other products based on price only. Banks face the likelihood that a significant portion of their customer base might turn to the convenience of digital aggregators, resulting in the migration of their accounts and the profit pools tied to them.

Sustaining Long Term Growth Through Business Transformation

The business transformation gained from adopting a platform-based open banking ecosystem will foster an environment that goes beyond incremental change and value delivery. It incorporates strategic choices that affect financial institutions’ growth – how they operate and the kind of improvements they can expect going forward.

Listed below are a few imperatives for creating long term growth for financial institutions:

  • Improve the existing range of offerings by reinforcing the core through collaboration with third-party providers.
  • Build new value propositions by incorporating customer needs and financial position within service integration. This will allow credit scoring, pricing of loans, and other products to be refined and curated on a more personal, almost one-to-one basis.
  • Collaboration and partnership between banks, third-party providers, and merchants will create a marketplace-like ecosystem. Allowing financial products to be bundled along with other non-financial products leads to newer cross-selling opportunities.
  • Diversify the traditional service portfolio by building strong API portfolios, boosting engagement with the developer community, and promoting cross-collaboration across marketplaces.
  • Concentrate on the adoption of the Banking-as-a-Platform (BaaP) model with an API-enabled network of partners, allowing core services to be bundled with third-party providers – facilitating advisory, business management as well as traditional banking services.

It is clear that open banking is set to fundamentally alter the financial service landscape through innovative services and new business models. The emergence of fintech will bolster collaboration as well usher in a new ecosystem that will change the role of banks significantly. Also, there are several issues surrounding regulation and data privacy causing a varied approach toward implementation across countries. However, irrespective of their geography, the momentum gathered by open banking is high, requiring banks and other fintech institutions to increase collaboration with each to ensure success within this new emerging ecosystem.

Understanding Critical Scalability Challenges in IoT & How to Solve them

While the vision for interconnected networks of “things” has existed for several decades; its execution has been limited due to an inability to create end-to-end solutions. Particularly the absence of a compelling and financially-viable business application for wide-scale adoption.

Decades of research into pervasive and ubiquitous computing techniques have led to a seamless connection between the digital and physical worlds. Facilitating an increase in the consumer and industrial adoption of Internet Protocol (IP)-powered devices. Several industries are now adopting creative and transformative methods for exploiting the ‘Code Halo’ or ‘data exhaust’ that exists between people, processes, products, and operations.

Currently, there are endless opportunities to create smart products, smart processes, and smart places, nudging business transformation across products and offerings. Smart connected products offer an accurate insight into how customers use a product, how well the product is performing, and a fresh perspective into overall customer satisfaction levels. Moreover, companies that previously only interacted with their customers at the initial purchase can now establish an ongoing relationship that progresses positively over time.

Future Promise – Business Transformation through IoT

Business Transformation through IoT

Let’s begin with considering the immediate future – in the next few years, the term ‘IoT’ will cease to exist in our vernacular. The discussions will instead shift to the purpose of IoT and the business transformation that is realized. We will see the emergence of completely new business models, products-as-a-service, smart cities, intelligent buildings, remote patient monitoring capabilities, and industrial transformational models. Order-of-magnitude improvements will be at the forefront as business intelligence boosts efficiency, waste reduction, predictive maintenance, and other forms of value.

The capturing of ambient data from the physical world to develop better products, processes, and customer services will be a core aspect of every business. The conversation will shift from how things are to be ‘connected’ and focus more on the insights gained from the instrumentation of large parts of the value chain. IoT technologies will become a commodity.

The real value will be unlocked through the analytics performed on the massive streams of contextual data transmitted by the ‘digital heartbeat’ of the value chain. IoT will form the crux of how products operate and the way physical business processes progress. In the future we expect the instrumentation-to-insights continuum to become the standard method of conducting business.

Layers of an IoT Architecture

Incorporating connectivity, computation, and interactivity directly into everyday things is dependent on organizations and requires an in-depth understanding of industry business problems, new instrumentation technologies and techniques, and the physical nature of the environment being instrumented.

Generally, IoT solutions are characterized by three-tier architecture:

IoT Architecture

IoT Architecture
  • Physical instrumentation via sensors and/or devices.
  • An edge gateway, which includes communication protocol translation support, edge monitoring, and analysis of the devices and data.
  • Public/private/hybrid cloud-based data storage and complex big data analytics implemented within enterprise back-end systems.

Successful business transformation initiatives leverage these IoT tiers against a specific industry challenge to gain a market advantage. Lastly, these IoT integrations should be configured to the actual physical environments in which the instrumentation technology will be deployed and aligned with the business focus areas for each organization. This usually requires organizations to leverage third-party expertise or various other complementary sets of ecosystem partnerships.

Scalability Challenges in IoT

With the explosion in market share, aspects such as network security, identity management, data volume, and privacy are sure to pose challenges and IoT stakeholders must address these challenges to realize the full potential of IoT at scale.

Network Security: The explosion in the number of IoT devices has created an urgent need to protect and secure networks against malicious attacks. To mitigate risk, the best practice is to define new protocols and integrate encryption algorithms to enable high throughput.

Privacy: IoT providers must ensure the anonymity and individuality of IoT users. This problem gets compounded as more IoT devices are connected within an ever-expanding network.

Governance: Lack of distinguished governance in IoT systems for building trust management between the users and providers leads to a breach of confidence between the two entities. This situation happens to be the topmost concern in IoT scalability.

Access Control: Incorporating effective access control is a challenge due to the low bandwidth between IoT devices and the internet, low power usage, and distributed architecture. This necessitates the refurbishment of conventional access control systems for admins and end-users whenever new IoT scalability challenges occur.

Big Data Generation: IoT systems carry out programmed judgments leveraging categorized data gathered from numerous sensors. This data volume increases exponentially and disproportionately to the number of devices. The challenge of scaling lies in large silos of Big Data generated as determining the relevance of this data will need unprecedented computing power.

Similar to most technology initiatives, the business cases are realized only when these technologies are implemented at scale. The connection of only a few devices isn’t enough to harness the full potential power of IoT for developing more meaningful products, processes, and places to elevate business performance.

What Companies Get Wrong About IoT

What Companies Get Wrong About IoT

Avoid a fragmented approach to IoT

Typically, companies, especially large multinational corporations that have global footprints do not have a clear owner of IoT within the organization. This leads to a fragmented and decentralized decision-making process when it comes to IoT.

For example, consider a company that has many factories across the world. Each factory has a bespoke application and a bespoke vendor for providing a single discrete use case. Each factory works well when we consider its individual silos, however, it is very difficult to gain an aggregated view across the entirety of the company as a whole. This leads to problems with scaling as the company is structurally limited, resulting in the company having to scale back to begin implementing and reengineering the process from the ground level.

When it comes to the IoT agenda, multinational companies need to be mindful of the short term and long term, at a global and a local level, to effectively capture IoT value. It is imperative to unite the business processes with technology as well as instill a change in mentality towards IoT value to derive real change within these companies. This includes having a completely different approach towards KPIs, incentives, and the performance management of people on a very practical level.

Overcoming the Challenges of IoT Scale

To rapidly progress from prototyping to real-world deployment, it is essential to focus on the challenges of scaling IoT:

1. Zero in on the underlying business problem or opportunity.
Change the mindset surrounding IoT with regards to technology experimentation leading to business transformation, starting with the company’s most valuable assets. A well-orchestrated engagement between the COO and CIO, a CFO-ready business plan, product, delivery, and customer service is a prerequisite for effectively scaling IoT.

2. Learning how IoT amplifies value.
Whenever an object is integrated into an IoT system, it acquires a unique persistent identity along with the ability to share information about its state. As a result, the value of an intelligent object is amplified throughout its lifecycle – from creation, manufacturing, delivery, and subsequent use, till its demise. This also includes its network of suppliers, producers, partners, and customers, whose interactions and access are handled by the IoT. During IoT exploration, whenever a product’s lifecycle and network are taken into account, it paints a clearer picture of the potential for structural transformation of processes, networks, and even the product itself.

3. Consider the Physical Nature of the Environment.
IoT provides connectivity to everyday objects that are rooted in a physical place. This leads to two critical dimensions of IoT scaling:

  • An understanding of the interplay between objects, between objects and people, and between objects and the environment (which further necessitates a deep understanding of the setting and inner workings of the physical place).
  • An understanding of how the physical environments themselves might affect the connectivity and successful interaction of objects. As IoT is reliant on wireless radio waves to transmit data from objects, any radio interference in a physical environment can impact transmission and must be considered during system design.

IoT scale aims to ensure that individual systems communicate with each other within the physical world and become invisible, blending seamlessly into the workplace. This requires a deep understanding of the inner workings of the physical place and the ability to translate technology within said environment. For instance, a “digital oilfield” IoT concept might foster a relationship between oil and gas consultants that understand industry pressures, drilling rig personnel that know the physical nature of day-to-day operations, and IoT technology experts capable of calibrating and connecting the devices within the environment.

4. Embrace the concept “it takes a village” to unite all IoT ingredients.
IoT is a “system of systems” composed of several different ingredients and expertise, dependent on end-to-end systems integration. These elements can fuel a transformation within a business model and develop coordinated initiatives designed for scale. Enrolling partners with the necessary domain expertise, and with a reputed history of integrating IoT technologies, will be key for establishing a long-term roadmap for IoT strategy and implementation.

An Integrated Approach Is Necessary For Driving End-To-End Transformation Across Business, Organization, And Technology

Driving end-end transformation

Realizing Full IoT Value

Adaptive organizations will quickly transcend IoT workshops and pilots to establish a long-term roadmap that is fueled by their business’ vision for the future and not technology. IoT can be incredibly disruptive and valuable across an industry, meaning that early adopters helping companies understand how to bring basic connectivity within their organization, will often fall short of unlocking the underlying business value that can be realized at scale. To make a meaningful impact on the business model, the product, and/or operational processes, businesses must implement IoT in a coordinated effort – across functions – at scale. This necessitates vision and leadership, outside expertise, and an ecosystem of partners for delivering a successful IoT journey.

CI/CD Pipeline: Understanding What it is and Why it Matters

The cloud computing explosion has led to the development of software programs and applications at an exponential rate. The ability to deliver features faster is now a competitive edge.

To achieve this your DevOps teams, structure & ecosystem should be well-oiled. Therefore it is critical to understand how to build an ideal CI/CD pipeline that will help to deliver features at a rapid pace.

Through this blog, we shall be exploring important cloud concepts, execution playbooks, and best practices of setting up CI/CD pipelines on public cloud environments like AWS, Azure, GCP, or even hybrid & multi-cloud environments.


Let’s take a closer look at what each stage of the CI/CD involves:

Source Code:

This is the starting point of any CI/CD pipeline. This is where all the packages and dependencies relevant to the application being developed are categorized and stored. At this stage, it is vital to have a mechanism that offers access to some reviewers in the project. This prevents developers from randomly merging bits of code into the source code. It is the reviewer’s job to approve any pull requests in order to progress the code into the next stage. Although this involves leveraging several different technologies, it certainly pays off in the long run.


Once a change has been committed to the source and approved by the reviewers, it automatically progresses to the Build stage.

1) Compile Source and Dependencies The first step in this stage is pretty straightforward, developers must simply compile the source code along with all its different dependencies.

2) Unit Tests This involves conducting a high coverage of unit tests. Currently, many tools show whether or not a line of code is being tested. To build an ideal CI/CD pipeline, the goal is to essentially commit source code into the build stage with the confidence that it will be caught in one of the later steps of the process. However, if high coverage unit tests are not conducted on the source code then it will progress directly into the next stage, leading to errors and requiring the developer to roll back to a previous version which is often a painful process. This makes it crucial to run a high coverage level of unit tests to be certain that the application is running and functioning correctly.

3) Check and Enforce Code Coverage (90%+) This ties into the testing frameworks above, however, it deals with the output code coverage percent related to a specific commit. Ideally, developers want to achieve a minimum of 90% and any subsequent commit should not fall below this threshold. The goal should be to achieve an increasing percentage for any future commits – the higher the better.

Test Environment:

This is the first environment the code enters. This is where the changes made to the code are tested and confirmed that they’re ready for the next stage, which is something closer to the production stage.

1) Integration Tests The primary thing to do as a prerequisite is to run integration tests. Although there are different interpretations of what exactly constitutes an integration test and how they compare to functional tests. To avoid this confusion, it is important to outline exactly what is meant when using the term.

In this case, let’s assume there is an integration test that executes a ‘create order’ API with an expected input. This should be immediately followed with a ‘get order’ API and checked to see if the order contains all the elements expected of it. If it does not, then there is something wrong. If it does then the pipeline is working as intended – congratulations.

Integration tests also analyze the behavior of the application in terms of business logic. For instance, if the developer inputs a ‘create order’ API and there’s a business rule within the application that prevents the creation of an order where the dollar value is above 10,000 dollars; an integration test must be performed to check that the application adheres to that benchmark as an expected business rule. In this stage, it is not uncommon to conduct around 50-100 integration tests depending on the size of the project, but the focus of this stage should mainly revolve around testing the core functionality of the APIs and checking to see if they are working as expected.

2) On/Off Switches At this point, let’s backtrack a little to include an important mechanism that must be used between the source code and build stage, as well as between the build and test stage. This mechanism is a simple on/off switch allowing the developer to enable or disable the flow of code at any point. This is a great technique for preventing source code that isn’t necessary to build right away from entering the build or test stage or maybe preventing code from interfering with something that is already being tested in the pipeline. This ‘switch’ enables developers to control exactly what gets promoted to the next stage of the pipeline.

If there are dependencies on any of the APIs, it is vital to conduct testing on those as well. For instance, if the ‘create order’ API is dependent on a customer profile service; it should be tested and checked to ensure that the customer profile service is receiving the expected information. This tests the end-to-end workflows of the entire system and offers added confidence to all the core APIs and core logic used in the pipeline, ensuring they are working as expected. It is important to note that developers will spend most of their time in this stage of the pipeline.



The next stage after testing is usually the production stage. However, moving directly from testing to a production environment is usually only viable for small to medium organizations where only a couple of environments are used at the highest. But the larger an organization gets, the more environments they might need. This leads to difficulties in maintaining consistency and quality of code throughout the environment. To manage this, it is better for code to move from the testing stage to a pre-production stage and then move to a production stage. This becomes useful when there are many different developers testing things at different times like QA or a new specific feature is being tested. The pre-production environment allows developers to create a separate branch or additional environments for conducting a specific test.

This pre-production environment will be known as ‘Prod 1 Box’ for the rest of this article.

Pre-Production: (Prod 1Box)

A key aspect to remember when moving code from the testing environment is to ensure it does not cause a bad change to the main production environment where all the hosts are situated and where all the traffic is going to occur for the customer. The Prod 1 Box represents a fraction of the production traffic – ideally around less than 10% of total production traffic. This allows developers to detect when anything goes wrong while pushing code such as if the latency is really high. This will trigger the alarms, alerting the developers that a bad deployment is occurring and allowing them to roll back that particular change instantly.

The purpose of the Prod 1 Box is simple. If the code moves directly from the testing stage to the production stage and results in bad deployment, it would result in rolling back all the other hosts using the environment as well which is very tedious and time-consuming. But instead, if a bad deployment occurs in the Prod 1 Box, only one host is needed to be rolled back. This is a pretty straightforward process and extremely quick as well. The developer is only required to disable that particular host and the previous version of the code will be reverted to in the production environment without any harm and changes. Although simple in concept, the Prod 1 Box is a very powerful tool for developers as it offers an extra layer of safety when they introduce any changes to the pipeline before it hits the production stage.

1) Rollback Alarms When promoting code from the test stage to the production stage, several things can go wrong in the deployment. It can result in:

  • An elevated number of errors
  • Latency spikes
  • Faltering key business metrics
  • Various abnormal and expected patterns

This makes it crucial to incorporate the concept of alarms into the production environment – specifically rollback alarms. Rollback alarms are a type of alarm that monitors a particular environment and is integrated during the deployment process. It allows developers to monitor specific metrics of a particular deployment and that particular version of the software for issues like latency errors or if key business metrics are falling below a certain threshold. The rollback alarm is an indicator that alerts the developer to roll back the change to a previous version. In an ideal CI/CD pipeline these configured metrics should be monitored directly and the rollback initiated automatically. The automatic rollback must be baked into the system and triggered whenever it determines any of these metrics exceed or fall below the expected threshold.

2) Bake Period The Bake Period is more of a confidence-building step that allows developers to check for anomalies. The ideal duration of a Bake Period should be around 24 hours, but it isn’t uncommon for developers to keep the Bake Period to around 12 hours or even 6 hours during a high volume time frame.

Quite often when a change is introduced to an environment, errors might not pop up right away. Errors and latency spikes might be delayed, unexpected behavior of APIs or a certain code flow of APIs doesn’t occur until a certain system calls it, etc. This is why the Bake Period is important. It allows developers to be confident with the changes they’ve introduced. Once the code has sat for the set period and nothing abnormal has occurred, it is safe to move the code onto the next stage.

3) Anomaly Detection or Error Counts and Latency Breaches During the Bake period, developers can use anomaly detection tools to detect issues however that is an expensive endeavor for most organizations and often is an overkill solution. Another effective option, similar to the one used earlier, is to simply monitor the error counts and latency breaches over a set period. If the sum of the issues detected exceeds a certain threshold then the developer should roll back to a version of the code flow that was working.

4) Canary A canary tests the production workflow consistently with expected input and expected outcome. Let’s consider the ‘create order’ API we used earlier. In the integration test environment, the developer should set up a canary on that API along with a ‘cron job’ that triggers every minute.

The cron job should be given the function of monitoring the create order API with expected input and hardcoded with an expected output. The cron job must continually call or check on that API every minute. This would allow the developer to immediately know when this API begins failing or if the API output results in an error, notifying that something wrong has occurred within the system.

The concept of the canary must be integrated within the Bake Period, the key alarms as well the key metrics. All of which ultimately links back to the rollback alarm which reverts the pipeline to a previous software version that was assumed to be working perfectly.

Main Production:

When everything is functioning as expected within the Prod 1 Box, the code can be moved on to the next stage which is the main production environment. For instance, if the Prod 1 Box was hosting 10% of the traffic, then the main production environment would be hosting the remaining 90% of that traffic. All the elements and metrics used within the Prod 1 Box such as rollback alarms, Bake Period, anomaly detection or error count and latency breaches, and canaries, must be included in the stage exactly as they were in the Prod 1 Box with the same checks, except on a much larger scale.

The main issue most developers face is – ‘how is 10% of traffic supposed to be directed to one host while 90% goes to another host?’. While there are several ways of accomplishing this task, the easiest is to transfer it at the DNS level. Using DNS weights, developers can shift a certain percentage of traffic to a particular URL and the rest to another URL. The process might vary depending on the technology being used but DNS is the most common one that developers usually prefer to use.



The ultimate goal of an ideal CI/CD pipeline is to enable teams to generate quick, reliable, accurate, and comprehensive feedback from their SDLC. Regardless of the tools and configuration of the CI/CD pipeline, the focus should be to optimize and automate the software development process.

Let’s go Over the key Points Covered One More Time. These are the key Concepts And Elements that Make up an Ideal CI/CD Pipeline:

  • The Source Code is where all the packages and dependencies are categorized and stored. It involves the addition of reviewers for the curation of code before it gets shifted to the next stage.
  • Build steps involve compiling code, unit tests, as well as checking and enforcing code coverage.
  • The Test Environment deals with integration testing and the creation of on/off switches.
  • The Prod 1 Box serves as the soft testing environment for production for a portion of the traffic.
  • The Main Production environment serves the remainder of the traffic

Thriving in a Digital Society — Modernizing Legacy Banking Applications

For more than half a century, banks have been at the frontier in embracing automation and introducing digital systems to gain operational excellence. Today, their demands have grown and banks now look beyond their legacy core banking systems that have been, to date, leveraged for conventional services such as opening up new accounts, processing deposits and transactions, and initializing loans.

Digital innovations are disrupting the marketplace and the continuous evolvement and spurt of technologies have now radically put these legacy systems back in the race. New players are beginning to enter the market without the burden of outdated technologies.

The rise of Fintech startups, teeth-gritting competition, and the fast-paced digital momentum have exponentially elevated consumer expectations and have forced banks to modernize their digital assets.

What is Core Banking Modernization?

Core banking modernization is the replacement, upgrade or outsourcing of a banks’ existing core banking systems and IT environment, which can be scaled and sustained to perform mission-critical operations for the bank, empowering it to harness the power of advancements in technology and design.

Banking Yesterday, Banking Today, and Banking Tomorrow

The core banking solutions of the future shall accommodate global perspectives so that it gets easier for the banks to deploy systems across multiple geographies. In comparison with the legacy systems, these new systems shall be more lean, scalable, process-centric, economical, and deployed over the cloud which shall empower banks to be agile and meet the changing business requirements.


In pursuit of embracing innovative features and scaling customer experience, the banks are at a disposition where they seem to be keen on accepting data-driven and cutting-edge technologies, and lean and agile processes. This transformation is disruptive and banks need to strike the right balance between revitalizing their core systems vis-à-vis creating new products and services to thrive in a digital society.

To address the challenges of the near future and the next normal, it is necessary to conduct a thorough assessment of the current core banking platform and external environments. Modernizing legacy applications is a critical process and it requires a disciplined and well-thought approach. Banks will need to understand whether a full replacement or a systematic upgrade will offer a better value-to-risk ratio.

Modernization Objectives and Drivers

Core banking modernization is driven by the need to respond to internal business imperatives such as growth and efficiency as well as the external ones such as regulations, competition, and customer experience expectations.

As new banking products, channels, and technologies enter the marketplace, the complexity and the necessity to modernize old legacy core banking systems becomes more crucial. The internal and the external drivers pushing the banks to transform are worth consideration.

Internal Drivers:

  • Product and Channel Growth
    Managing high volumes of product-channel transactions and payments demand scalable and sustainable modern core banking systems. The introduction of ever-increasing custom solutions/products to satiate a wide segment of customers which is further amplified with multifarious channels creates an opportunity for banks to re-strategize their old digital assets.
  • Legacy Systems Management
    With technologies that had been used to build the legacy systems getting obsolete, finding resources to manage these outdated systems also gets difficult. Moreover, introducing new technologies into the systems benefit the banks in staying relevant, achieving flexibility and cost-effectiveness.
  • Cost Reduction
    Modernizing core applications involves consolidating the other stand-alone applications that stand peripheral to the core. This subsequently optimizes the overall cost and helps banks in reducing the high maintenance costs associated with legacy systems.

External Drivers:

  • Regulatory Compliance
    It is imperative for the banks to enhance their IT infrastructure and operations in order to comply with increasing regulations such as Basel III, Foreign Account Tax Compliance Act (FATCA), and the Dodd-Frank Act, all of which are aimed at 1) Enhancing risk management 2) Governance procedures and, 3) Improving transparency of banking operations that also involves customer interactions.
  • Increasing Competition
    The competition pressure compels banks to innovate and embrace new core banking platforms. The new entrants in financial services are speculated to give banks a tough run and start questioning their purpose of existence.
  • Customer Centricity
    Customer experience is a derivate of many components and banks need to re-strategize their positioning. Moving from a product-centric to a customer-centric approach is highly necessary. Focus on customer service, relationship-based pricing, and digital experience shall be the crucial elements in the transformation journey.


Best Practices in Core Banking Modernization

  • Evaluate Technical Debt: Banks should be able to closely identify and calculate their technical debt so that they can properly prioritize the debt and its impact on the legacy system processes. To get an accurate assessment, banks will need to factor in the prospective cost of adding or altering features and functionality later.
  • Outline the Organization’s Objectives and Analyze Risk Tolerance: When going for legacy system modernization, the bank must assess various business variables like customer satisfaction levels, modernization objectives, cost savings, business continuity, and risk management. These thorough assessments will help to provide context for the selection of the most efficient and effective modernization approach.
  • Choose Futuristic & Advanced Solutions: Technology refinements are taking place at an unprecedented scale, which demands organizations to be agile in the adoption of future technologies. For this, it is critical to build solutions that support future adaptability.
  • Define the Post-Modernization Release Strategy: The most crucial modernization practice is to create a follow-up plan that includes successful training of employees, ensuring systematic and streamlined process, timely update schedule, and undertaking other maintenance tasks.

Legacy modernization will empower traditional banks in performing a wide range of modern banking services which shall be robust and scalable. Moreover, the digitalization of traditional banks shall address the changing needs of customers through seamless digital services and drive excellent customer experience.

Legacy Modernization Benefits

  • Faster Customer Onboarding: Deploy cutting-edge technologies such as Artificial Intelligence, Blockchain, Data Science, etc. to speed up the customer onboarding process. Remember, that the customer experience is a derivative of the way banks engage with them and makes their life easier and better.
  • Omnichannel Banking Experience: Your online and mobile banking software should not only match but supersede the banking experience drawn at your physical banks. This simply means that the virtual banking experience of your customer should be seamless, personalized, and secured.
  • Scalability and Flexibility: Your banking application should be able to onboard any number of users and be fit for massive user access at the same time. Cloud adoption is proving to improve efficiency, security, and reduced costs.


The Way Forward

As the world tunes in to the new normal, the solution to legacy systems is the modernization of core banking systems. Banks looking to enhance their IT efficiency are sorting to innovative technologies of AI/ML, IoT, Cloud Computing, Blockchain, and RPA. The integration of new technologies shall help in unlocking the growth and revenue potentials of banks whilst building a loyal and satisfied customer base. It also enables real-time systems that are agile, scalable, flexible, and cost-effective.

Now is not the time to mull over the prospect of banking legacy software modernization. It is only the survival of the fittest, and to stay fit, banks and financial institutions must weather the storm and adapt to the new rapid evolution of Fintech. This however can’t be a solitary journey!

The Best VS Code Extensions For Remote Working

What do developers want? Money, flexible schedules, pizza? Sure. Effortless remote collaboration? Hell, yes! Programming is a team sport and without proper communication, you can’t really expect spectacular results. A remote set-up can make developer-to-developer communication challenging, but if equipped with the right tools, you have nothing to fear. Let’s take a look at the best VS Code extensions that can seriously improve a remote working routine.

1. Live Share

If you’ve been working remotely for a while now, chances are you’re already familiar with this one. This popular extension lets you and your teammates edit code together.

It can also be enhanced by other extensions such as Live Share Audio which allows you to make audio calls, or Live Share Whiteboard to draw on a whiteboard and see each other’s changes in real-time.

Benefits for remote teams: Boost your team’s productivity by pair-programming in real-time, straight from your VS Code editor!

2. GitLive

This powerful tool combines the functionality of Live Share with other super useful features for remote teams. You can see if your teammates are online, what issue and branch they are working on and even take a peek at their uncommitted changes, all updated in real-time.

But probably the most useful feature is merge conflict detection. Indicators show in the gutter where your teammates have made changes to the file you have open. These update in real-time as you and your teammates are editing and provide early warning of potential merge conflicts.

Finally, GitLive enhances code sharing via LiveShare with video calls and screen share and even allows you to codeshare with teammates using other IDEs such as IntelliJ, WebStorm or PyCharm.

Benefits for remote teams: Improve developer communication with real-time cross-IDE collaboration, merge conflict detection and video calls!

3. GistPad

Gists are a great way not only to create code snippets, notes, or tasks lists for your private use but also to easily share them with your colleagues. With GistPad you can seamlessly do it straight from your VS Code editor.

You can create new gists from scratch, from local files or snippets. You can also search through and comment on your teammate’s gists (all comments will be displayed at the bottom of an opened file or as a thread in multi-file gists).

The extension has broad documentation and a lot of cool features. What I really like is the sorting feature, which when enabled, will group your gists by type (for example note — gists composed of .txt, .md/.markdown or .adoc files, or diagram — gists that include a .drawio file) which makes it super-easy to quickly find what you’re looking for.

Benefits for remote teams: Gists are usually associated with less formal, casual collaboration. The extension makes it easier to brainstorm over the code snippet, work on and save a piece of code that will be often reused, or share a task list.

4. Todo Tree

If you create a lot of TODOs while coding and need help in keeping track of them, this extension is a lifesaver. It will quickly search your workspace for comment tags like TODO and FIXME and display them in a tree view in the explorer pane.

Clicking on a TODO within the tree will bring you to the exact line of code that needs fixing and additionally highlight each to-do within a file.

Benefits for remote teams: The extension gives you an overview of all your TODOs and a way to easily access them from the editor. Use it together with your teammates and make sure that no task is ever forgotten.

5. Codetour

If you’re looking for a way to smoothly on-board a new team member to your team, Codetour might be exactly what you need. This handy extension allows you to record and playback guided walkthroughs of the codebase, directly within the editor.

A “code tour” is a sequence of interactive steps associated with a specific directory, file or line, that includes a description of the respective code and is saved in a chosen workspace. The extension comes with built-in guides that help you get started on a specific task (eg. record, export, start or navigate a tour). At any time, you can edit the tour by rearranging or deleting certain steps or even change the git ref associated with the tour.

Benefits for remote teams: A great way to explain the codebase and create project guidelines available within VS Code at any time for each member of the team!

6. Git Link

Simple and effective, this extension does one job: allows you to send a link with selected code from your editor to your teammates, who can view it in GitHub. Besides the advantage of sharing code with your team (note that only committed changes will be reflected in the link), it is also useful if you want to check history, contributors, or branch versions.

Benefits for remote teams: Easily send links of code snippets to co-workers.


Good communication within a distributed team is key to productive remote working. Hopefully, some of the tools rounded up in this short article will make your team collaboration faster, more efficient and productive. Happy hacking!

Key Comparative Insights between React Native and Flutter

The increasing demand for mobile apps gets every business to look for the best and robust solution. Understanding the pros and cons of each platform is necessary. In this blog, we share key comparative insights on the popular cross-platform technologies – React Native and Flutter.

React Native was built and open-sourced by Facebook in 2015 with easy access to the native UI components and the code is reusable. A hot reload feature is available with access to high-quality third-party libraries.

Flutter is an open-source technology launched by Google which has a robust ecosystem and offers maximum customization.

Programming Language

React Native mainly uses JavaScript as the programming language, which is a dynamically typed language. ReactJS is a JavaScript library mainly used for building user interfaces. ReactJS is used across various web applications, a specific pathway to build out its forms has to be used which is accomplished by using – ReactJS lifecycle.

On the other hand, Flutter uses Dart which was introduced by Google in 2011. It is similar to most other Object-Oriented Programming Languages and has been quickly adopted by developers as it is more expressive.


React Native uses the JavaScript bridge, which is the JavaScript runtime environment that provides a pathway to communicate with the native modules. JSON messages are used to communicate between the two sides. This process requires a smooth User Interface. The Flux architecture of Facebook is used by React Native.

Flutter contains most of the required components within itself which rules out the need for a bridge. Frameworks like Cupertino and Material Design are used. Flutter uses the Skia engine for its purpose. The apps built on Flutter are thus more stable.


React Native can easily be installed by someone with little prior knowledge of JavaScript. It can be installed by using the React Native CLI- which needs to be installed globally. The prerequisites for installing React Native are NodeJS and JDK8. The yarn needs to be installed to manage the packages.

Installing Flutter is a bit different. The binary for a specific platform needs to be downloaded. A zip file is also required for macOS. It is then required to be added to the PATH variable. Flutter installation does not require any knowledge of JavaScript and involves a few additional steps in comparison with React Native.

Setup and Project Configuration

React Native has limitations while providing a setup roadmap and it begins with the creation of a new project. There is less guidance while using Xcode tools. For Windows, it requires JDK and Android Studio to be preinstalled.

Flutter provides a detailed guide to installing it. Flutter doctor is a CLI tool that helps developers to install Flutter without much trouble. Flutter provides better CLI support and a proper roadmap to setting up the framework. Project configuration can be done easily as well.

UI Components and Development API

React Native has the ability to create the Native environment for Android and iOS by using the JS bridge. But it relies heavily on third-party libraries. The React Native components may not behave similarly across all platforms thereby making the app inconsistent. User Interface rendering is available.

Flutter provides a huge range of API tools, and the User Interface components are in abundance. Third-party libraries are not required here. Flutter also provides widgets for rendering UI easily across Android and iOS.

Developer Productivity

The React Native codes are reusable across all the platforms. JavaScript is supported by all editors. React Native also provides the Hot Reload feature. This means that any changes in the backend will be directly visible on the front end, even without recompilation.

Flutter also offers the Hot Reload feature. The compilation time on Flutter is shorter as compared to React Native. This affects Flutter VS React Native development speed comparison. But all editors do not support Dart as it is not common.

Community Support

Communities also help in sharing knowledge about specific technology and solving problems related to it. Since being launched in 2015, React Native has gained popularity and has increasing communities forming across the world, especially on GitHub.

Flutter started gaining popularity in 2017 after the promotion by Google and the community is relatively smaller, but a fast-growing one. Currently, React Native has larger community support, however, Flutter is being acknowledged globally and is also fast-trending.

Testing Support

The React Native framework does not provide any support for testing the UI or the integration. JavaScript offers some unit-level testing features. Third-party tools need to be used for testing the React Native apps. No official support is provided for these tests.

Flutter provides a good set of testing features. The Flutter testing features are properly documented and officially supported. Widget testing is also available that can be run like unit tests to check the UI. Flutter is hence better for testing.

DevOps and CI/CD Support

Continuous Integration and Continuous Delivery are important for apps to get feedback continuously. React Native does not offer any CI/CD solution, officially. It can be introduced manually, but there is no proper guideline to it and third-party solutions need to be used.

Setting up a CI/CD with Flutter is easy. The steps are properly mentioned for both iOS and Android platforms. Command Line Interface can easily be used for deploying them. React Native DevOps is properly documented and explained. DevOps lifecycle can also be set up for Flutter. Flutter edges React Native in terms of DevOps and CI/CD support because of the official CI/CD solution.

Use Cases

React Native is used when the developer is accustomed to using JavaScript. The more complicated apps are created using the React Native development framework.

If the User Interface is the core feature of your app, you should choose Flutter. Flutter is used for building simple apps with a limited budget. Thus you should consider the main use case of your app before finalizing the technology stack. The target of Google is to improve Flutter’s performance for desktops mainly. This will allow developers to create apps for the desktop environment. React Native may use the same codebase to develop apps for both Android and iOS.


React Native and Flutter both have their pros and cons. React Native might be the base of a majority of currently existing apps, but Flutter is quickly gaining popularity within the community since its inception, a fact further boosted by the advancement of the Flutter Software Development Kit (SDK) which makes the framework more advanced and preferable. The bottom line is to use the right platform after a thorough need-analysis is done. Contact NeoSOFT Technologies for a free consultation to help you get ready for a ‘mobile-journey’.

The Ultimate Guide to Big data for businesses

The term “big data” refers to data that is so large, fast or complex that it’s difficult or impossible to process using traditional methods. The act of accessing and storing large amounts of information for analytics has been around for a long time. Big data essentially is a large volume of data – both structured and unstructured – that inundates a business on a day-to-day basis. But it’s not the amount of data that’s important. It is what the organizations do with the data that matters

Importance Of Big Data For Businesses

The Big Data concept was born out of the need to understand trends, preferences, and patterns in the huge database generated when people interact with different systems and each other. With Big Data, business organizations can use analytics, and figure out the most valuable customers. It can also help businesses create new experiences, services, and products.

Using Big Data has been crucial for many leading companies to outperform the competition. In many industries, new entrants and established competitors use data-driven strategies to compete, capture and innovate. You can find examples of Big Data usage in almost every sector, from IT to healthcare.

Types Of Big Data

Big Data is widely classified into three main types

  • Structured: This data has some pre-defined organizational property that makes it easy to search and analyze. The data is backed by a model that dictates the size of each field: its type, length, and restrictions on what values it can take. An example of structured data is “unit’s produced per day”, as each entry has a defined ‘product type’ and ‘number produced’ fields.
  • Unstructured: This is the opposite of structured data. It doesn’t have any pre-defined organizational property or conceptual definition. Unstructured data makes up the majority of big data. Some examples of unstructured data are social media posts, phone call transcripts, or videos.
  • Semi-structured: The line between unstructured data and semi-structured data has always been unclear since most of the semi-structured data appears to be unstructured at a glance. Information that is not in the traditional database format as structured data, but contains some organizational properties which make it easier to process. For example, NoSQL documents are considered to be semi-structured, since they contain keywords that can be used to process the document easily

Categories Of Big Data: The Many V’s

Big data commonly is characterized by a set of V’s, using words that begin with v to explain its attributes. Doug Laney, a former Gartner analyst who now works at consulting firm West Monroe, first defined three V’s — volume, variety and velocity — in 2001. Many people now use an expanded list of five V’s to describe big data:

  • Volume: There’s no minimum size level that constitutes big data, but it typically involves a large amount of data — terabytes or more.
  • Variety: Big data includes various data types that may be processed and stored in the same system.
  • Velocity: Sets of big data often include real-time data and other information that’s generated and updated at a fast pace.
  • Veracity: This refers to how accurate and trustworthy different data sets are, something that needs to be assessed upfront.
  • Value: Organizations also must understand the business value that sets of big data can provide to use it effectively.

Another V that’s often applied to big data is variability, which refers to the multiple meanings or formats that the same data can have in different source systems. Lists with as many as 10 V’s have also been created.

Examples And Use Cases Of Big Data

Big data applications are helpful across the business world, not just in tech. Here are some use cases of Big Data:

  • Product Decision Making: Big data is used by companies to develop products based on upcoming product trends. They can use combined data from past product performance to anticipate what products consumers will want before they want it. They can also use pricing data to determine the optimal price to sell the most to their target customers.
  • Testing: Big data can analyze millions of bug reports, hardware specifications, sensor readings, and past changes to recognize fail-points in a system before they occur. This helps maintenance teams prevent the problem and costly system downtime.
  • Marketing: Marketers compile big data from previous marketing campaigns to optimize future advertising campaigns. Combining data from retailers and online advertising, big data can help fine-tune strategies by finding subtle preferences to ads with certain image types, colours, or word choice.
  • Healthcare: Medical professionals use big data to find drug side effects and catch early indications of illnesses. For example, imagine there is a new condition that affects people quickly and without warning. However, many of the patients reported a headache on their last annual check-up. This would be flagged a clear correlation using big data analysis but may be missed by the human eye due to differences in time and location.
  • Customer Experience: Big data is used by product teams after a launch to assess the customer experience and product reception. Big data systems can analyze large data sets from social media mentions, online reviews, and feedback on product videos to get a better indication of what problems customers are having and how well the product is received.
  • Machine learning: Big data has become an important part of machine learning and artificial intelligence technologies, as it offers a huge reservoir of data to draw from. ML engineers use big data sets as varied training data to build more accurate and resilient predictive systems.

Business Advantages Of Big Data

  • One of the biggest advantages of Big Data is predictive analysis. Big Data analytics tools can predict outcomes accurately, thereby, allowing businesses and organizations to make better decisions, while simultaneously optimizing their operational efficiencies and reducing risks.
  • By harnessing data from social media platforms using Big Data analytics tools, businesses around the world are streamlining their digital marketing strategies to enhance the overall consumer experience. Big Data provides insights into the customer pain points and allows companies to improve upon their products and services.
  • Being accurate, Big Data combines relevant data from multiple sources to produce highly actionable insights. Almost 43% of companies lack the necessary tools to filter out irrelevant data, which eventually costs them millions of dollars to hash out useful data from the bulk. Big Data tools can help reduce this, saving you both time and money.
  • Big Data analytics could help companies generate more sales leads which would naturally mean a boost in revenue. Businesses are using Big Data analytics tools to understand how well their products/services are doing in the market and how the customers are responding to them. Thus, they can understand better where to invest their time and money.
  • With Big Data insights, you can always stay a step ahead of your competitors. You can screen the market to know what kind of promotions and offers your rivals are providing, and then you can come up with better offers for your customers. Also, Big Data insights allow you to learn customer behaviour to understand the customer trends and provide a highly ‘personalized’ experience to them.
