Uma análise comparativa entre gRPC e REST para a integração de serviços Web

Abstract

With the emergence of software architectures such as microservices, there is a need for Software Integration, so that systems can exchange data with each other efficiently and performatively. And when the software architect plans the integration model, it is necessary to take into account some factors in the context of that software. One of the ways to integrate is through the request/response model, and among the existing technologies are REST, which is widely used, and gRPC, which is a relatively new but promising technology. Therefore, this study provides information by comparing REST and gRPC to assist in this choice. We conducted a case study, in which two services were built using both technologies and we researched the technical literature, comparing these two architectural styles through the Goal Question Metric approach. The outcome indicates that GRPC performs better in high-demand environments, and REST has better external integrations between services. The collected information was summarized in a comparison that assists the developer in the decision of which technology to use, thus contributing to the area of Software Integration.
