title: It's there any overhead while using Eureka and Zookeper(Kafka) in a JHipster Microservices environment?
body: <p>I'm actually building an microsysteme environment based on JHipster. But we have some questions about server overhead. 
  JHipster Registry used per default Eureka and we want to add a Kafka as queue. The point is: Kafka come with Zookeeper embedded.
  So Zookeeper and Eureka have good points when it's come to Service Discovery.</p>
  
  <p>Should i replace the default Eureka (Jhipster-registry) by Zookeeper? so that i just run one Zookeeper for Discovery and Kafka.</p>
  
  <p>Or should it will be no performance issues when i use the default setup? I will then need to start Eureka, Zookeeper and Kafka.</p>
