So far, we have seen the benefits of a microservice architecture over monolithic applications, and the components that we need to run a microservice application such as JHipster Registry, Consul, Zuul, Zipkin, the ELK stack, Hystrix, Prometheus, and the JHipster UAA server. In our next chapter, we will see how to build microservices using JHipster. We will also learn how we can choose the previous components and how easy it is to set them up with JHipster.
