In a microservice architecture, we need an entry point to access all the running services. So we need a service that acts as a gateway. This will proxy or route clients' requests to the respective services. In JHipster, we provide JHipster Gateway for that.
JHipster Gateway is a microservice application that can be generated. It integrates Netflix Zuul and Hystrix in order to provide routing, filtering, security, circuit breaking, and so on.
