Business Need

Ensuring efficient and timely processes is crucial for a credit card issuers and program managers, especially when it comes to delivering seamless services to customers.

The existing monolithic architecture was proving to be inflexible, hindering scalability, and impacting the ability to introduce new features quickly.

To stay competitive and meet customer expectations, platform modernization became a priority.


Recognizing the need for agility and scalability, the company embarked on a digital transformation journey by transitioning from a monolithic architecture to a microservices-based architecture. By leveraging microservices, the company aimed to achieve modularization, enabling independent development, deployment, and scalability of each service. Our team led the modernization program starting with reimagining the product architecture combining proven best practices like,

  • Distributed Architecture
  • Cloud-nativity along with absolute portability
  • Platform Engineering
  • Containerization and orchestration
  • Automation

We designed and developed a platform that provides all the foundational components to run all the micro-services with auto-scaling, observability, continuous delivery, and ultimate cloud portability.

To improve the architecture, 3 modules were chosen to be broken away from the existing monolithic application and rebuilt as micro-services following reimagined architecture. These modules were developed following the industry best practices.

  • Domain-driven
  • Command and Query Separation
  • Event-driven
  • Clean architecture

Business Benefits

The modernized platform now offers enhanced functionality, such as real-time card application processing, personalized rewards programs, and streamlined customer onboarding. By breaking down the monolithic structure into smaller, self-contained services, the company improved fault isolation and resilience, minimizing the impact of any potential failures.

Additionally, the adoption of modern development practices, like DevOps and continuous integration/continuous deployment (CI/CD), accelerated the release cycle and ensured faster time-to-market for new features and updates. In addition it now has a fully automated build and deployment with infrastructure provisioning that works both on the public and private data centres.

As a result of the digital modernization efforts, the credit card insurance company experienced increased operational efficiency, reduced maintenance costs, and enhanced customer satisfaction.

The microservices-based architecture enabled the company to embrace a more agile, scalable, and adaptable approach, empowering them to stay ahead in a competitive market while delivering seamless and innovative credit card services to their customers.
