Evaluation of Microservice Communication While Decomposing Monoliths

One of the biggest challenges while migrating from a monolith architecture to microservice is define proper communication technology. In applications, between components performed using in-process method or function calls, different methods have be established achieve same functionality in architecture. A microservices-based application distributed system running on multiple processes services. Therefore, microservices must interact inter-process technologies. This research aims evaluate synchronous and asynchronous technologies determine particular cases for their decomposing into cloud-native applications. Five technologies, such as HTTP Rest, RabbitMQ, Kafka, gRPC, GraphQL, been evaluated compared by proposed evaluation criteria. The advantages disadvantages each technology were identified context
