title: When to configure zuul routes
body: <p>I am new to spring cloud and going through some examples and material available online to make myself comfortable. However, while reading about ZUUL, some sites configured the routes in ZUUL's <code>application.yml</code> and some other sites mentioned that the requests will be forwarded to the respective microservice and no need to explicitly configure the routes. I was bit confused. For ex, in the below scenario what is the approach, to configure routes or to let zuul route automatically?</p>
  
  <ol>
  <li>Let's say i have few micro services running and all of them along with ZUUL are registered to Eureka. </li>
  <li>I have a front end which is running on a different port on the same server and needs to interact with the above micro services.</li>
  <li>I also have few other applications (Running entirely on different servers) which need to interact with the above micro services for fetching the data.</li>
  </ol>
  
  <p>TIA..</p>
