title: Can Zuul Edge Server be used without Eureka / Ribbon
body: <p>We have an infrastructure with service discovery and load balancing (i.e. server side with STM and weblogic cluster). Now we are in the process of refactoring into micro-services. We would need an API gateway which does basic routing to other microservices. Netflix Zuul looks a good candidate however I could not get Zuul working without Eureka - but we do not need Eureka since we already have service discovery and load balancing in place.</p>

  <li>Is it possible to use Zuul without Eureka and Ribbon?</li>
  <li>If yes please provide some guild-lines since the there's no mention about in the wiki.</li>
  </ol>
  
  <p>Thanks.</p>
