We have created our gateway and two microservice applications. The microservices have two different databases. So far, it has been easy and simple to create those with JHipster. 

JHipster provides two different options we have previously seen, Consul and JHipster Registry. For our use case, let's go with JHipster Registry. We have already learned about JHipster Registry in Chapter 8, Introduction to Microservice Server-Side Technologies. Now, we will see how to set up and start it in our local development environment.
