title: What means datacenter property in Spring Eureka server?
body: <p>In Spring Eureka server exists the property "datacenter",  what is the purpose of setting this? Do I need to set one if I am not running in standalone mode the server? Otherwise if I have zone/region for my peers, this property should have the same name to identify the zone they're? </p>
  
  <p>For example</p>
  
  <pre><code>eureka.datacenter=myname
  </code></pre>
