Avaliação comparativa entre implementação FaaS e microserviço de um software ERP

Abstract

Cloud-hosted services have grown and moved billions of dollars in recent years. Large hosting providers disputed this attractive market, which has provided different software architectures that derive mainly from the Service Oriented Architecture (SOA) standard. Microservice and Function as a Service (FaaS) are the most SOA adopted. Even though FaaS is a direct evolution of the Microservice standard, the two have differences that completely change the way they work with each one. In this case study, we investigate the impacts of each architecture on an Enterprise Resource Planning application. The results show that the conversion of the application to the two architectures allowed the reuse of code because the application is stateless. In terms of performance, Microservice proved to be around 40% better than FaaS for the 10 different types of requests implemented for the application.
