Using the GRPC protocol in the context of crisis management

Speed, stability, and efficiency are key parameters in inter-service communication for crisis management. Traditionally, microservice architecture has utilized REST (Representational State Transfer), an architectural style based on the principles of the HTTP protocol, due to its simplicity and broad support. However, with the increasing number of requests to and between microservices, the gRPC protocol is becoming an increasingly attractive alternative. This paper presents the technical advantages of the gRPC protocol over traditional REST in the context of inter-service communication for crisis management, focusing on several key parameters: low latency, efficiency, data streaming capabilities, and support for distributed transactions. The paper introduces the gRPC protocol through the Go programming language, which is also recognized as a highly efficient, reliable, and scalable language, making it very suitable for building microservices.
