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.
Should i replace the default Eureka (Jhipster-registry) by Zookeeper? so that i just run one Zookeeper for Discovery and Kafka.
Or should it will be no performance issues when i use the default setup? I will then need to start Eureka, Zookeeper and Kafka.
