<p>I would work with HA in Kubernetes, and i would identify how many nodes should i prepare to manage X workers</p>
<p>Is there a forumla to apply ?</p>
<p>And what is the best solution to implement as Load Balancer ? HaProxy or Nginx ..</p>
<p>Thanks</p>

<p>In Kubernetes you can manage up to 5000 worker nodes.</p>
<p>You need at least 3 control plane nodes, then you can scale this nodes vertically first, then horizontally (<a href="https://kubernetes.io/docs/setup/best-practices/cluster-large/" rel="nofollow noreferrer">documentation</a>).</p>
<p>If you plane to deploy a fixed number of control plane nodes, I don't have a strong opinion about the LB to use. Otherwise you need a dynamic LB.</p>
