title: Pod Communication
body: <p>How does the communication between two different pods happen in Kubernetes?</p>
  
  <p>In my case I have two pods: <em>frontend</em> and <em>backend</em>, both have different containers.
  I want my frontend pod to communicate with the backend pod but I don't want to use backend pod's IP( i.e.  hard coded). </p>
  
  <p>Is it possible through services? </p>
