Integration of a New Microservice with a Legacy System for Coforge

Coforge needed support in designing and developing a module responsible for saving SSR data in one of its microservices.

The key challenge was converting stored data into a format understood by the legacy system, enabling verification and further use in the existing environment.

The project required combining a new microservice-based approach with the existing architecture while maintaining data consistency, clear integration contracts, and testability of service behavior.

Edge One Solutions supported Coforge by providing IT specialists responsible for designing and developing a microservice module.

The scope of support included creating a component responsible for saving and reading SSR data in a modern application architecture.

The team also supported the preparation of a data conversion mechanism for the format handled by the legacy system, as well as integration testing using tools for simulating external services.

As part of the project, a dedicated microservice module was created for saving and reading SSR data.

The solution made it possible to process data in the new component and then convert it into a format understood by the legacy system, enabling verification and use in the existing environment.

The microservice-based approach helped isolate a specific responsibility into a separate module, supporting clearer architecture, easier testing, and further system modernization.

Enterprise system modernization rarely means replacing the entire architecture at once. More often, it requires gradually extracting responsibilities, creating new components, and integrating them with legacy systems in a controlled way.

The Coforge project shows how a dedicated microservice can support data saving, reading, and conversion while maintaining compatibility with the format required by the legacy system.

For organizations developing complex systems, a similar approach can reduce change risk, improve solution testability, and make further architecture evolution easier.
