Effective services communication through gRPC

On the project, the client had a problem with effective communication between various services operating in a distributed environment. Traditional methods of interaction, such as REST or SOAP, had certain limitations, especially in the area of performance and extensibility. In addition, the growing complexity of interaction between services required finding a more effective solution.

To solve this problem, we decided to use gRPC (Google Remote Procedure Call) – an open-source, high-performance RPC framework based on a simple but powerful Protocol Buffers serialization mechanism, which provides a compact data transfer format and supports various programming languages. In addition, gRPC supports multithreading, cross-server calls, and a system of extensibility.

Using gRPC allowed us to improve the performance and efficiency of communication between services, we noticed a significant increase in data transfer speed and a decrease in the amount of network traffic thanks to the compact format of Protocol Buffers. In addition, the flexibility and extensibility of gRPC allowed us to easily introduce new functions and change the interaction interface between services without interrupting the system. Even though some of the services were written in different programming languages, using gRPC allowed us to make them interoperate seamlessly. In general, the use of gRPC has greatly facilitated the work with distributed systems and improved their performance.
