<p>Conditions:
I have a <em>3 tier application</em> to deploy using Kubernetes. I have created <strong>two namespaces</strong> for <em>backend</em> and <em>frontend</em> respectively.</p>
<p>Problem:
I want to know how would my <strong>backend</strong> talk to the <strong>frontend</strong> or vice versa.</p>
<p>In simple words, how do backend and frontend communicate if they are in different namespaces?</p>

<p>applications can communicate with other services outside their namespace , just use the correct <a href="https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/" rel="nofollow noreferrer">dns name</a></p>
<pre><code>&lt;Service Aame&gt;.&lt;Namespace Name&gt;.svc.cluster.local
</code></pre>
