<p>How to manage traffic between pods replicas of several applications?
I would like to get the effect for application A and B</p>

<blockquote>
  <p>under A-x he always sent requests only to B-x and A-y only to B-y. And
  that the platforms A-y and B-x do not communicate with each other.</p>
</blockquote>

<p>Thank you in advance for all the answers.</p>
