Avaliação prática da abordagem Monolith First no desenvolvimento de aplicações com arquitetura de microsserviços

Abstract

This paper aims to evaluate the Monolith First approach in the development of microservices systems, through a case study involving the development of a system initially as a modular monolith, followed by its migration to microservices. The methodology adopted consists of five stages: requirements gathering, system design, modular monolith development, migration to microservices, and evaluation of the approach used. The analysis focuses on the effectiveness of the transition, highlighting the benefits of using Domain-Driven Design (DDD) and Clean Architecture in structuring the system. The study also explores the challenges faced, such as the implementation of communication between services using Apache Kafka and gRPC, and how data replication was essential to ensure service independence. The results demonstrate that the Monolith First approach facilitates the definition of bounded contexts, reduces the initial complexity of development, and allows for a faster and more efficient migration to microservices. The research concludes that this strategy is highly recommended for projects aiming to build a well-structured distributed architecture.
