Despite still being used nowadays, microservices have grown in popularity and are becoming the established architecture to build services. Service-oriented Architectures (SoA) are not new but the specialization into microservices, which are loosely coupled, and independently deployable smaller services, that focus on a single well-defined business case, became wildly popular since they enable:...
