Building middleware service and a set of microservices for the FinTech company 

The client operates a custom Enterprise Resource Planning (ERP) system that enables their customers to register and perform various operations. They sought to enhance their platform by integrating a new component. It meant adding a number of new solutions providers to their integrator. 

From a technical perspective, the requirement was to develop a lightweight microservices architecture, ensuring seamless scalability and the flexibility to integrate additional providers in the future. However, integrating multiple providers introduced compatibility challenges, including differences in data formats, APIs, and authentication methods. The solution needed to accommodate these variations while maintaining system stability and performance.

After thoroughly analyzing the client’s requirements, DigitalMara designed a robust and scalable architecture tailored to address both the functional and technical needs of the project. It’s a classical microservices architecture consisting of a middleware service, number of microservices and APIs that provide communication between all elements. 

All requests are received in middleware and then passed on to the corresponding microservice. The second step is for the microservice to contact the finance solution provider. And the same way back after completing the required action. In case of timeouts, the system automatically resends queries enhancing overall reliability. We have also ensured that the data is fed into the databases and can be used without interruptions.  

The entire architecture is built using .NET, and components communicate with each other via the HTTP protocol. Leveraging .NET and C# allows us to provide high performance, scalability, cross-platform compatibility and robust security. The architecture is designed to be flexible enough to accommodate different integration standards, including varied data formats, authentication methods, and other requirements. In addition, C# enables seamless integration with cloud services. 

By implementing the new microservices architecture, we established an efficient, scalable process for integrating an unlimited number of finance services providers. It’s a great foundation for managing future integrations. The system’s modular design also means that updates or additions to existing providers can be handled seamlessly, ensuring minimal disruption to ongoing operations. 

The client added a new offering to their suite of services, allowing them to expand their capabilities. This enhancement strengthens their service portfolio and provides their customers with more comprehensive solutions, further solidifying their competitive position in the market.
