title: Kubernetes HorizontalPodAutoscaler maxReplicas
body: <p>community.</p>
  <p>I have doubts about the use of HorizontalPodAutoscaler (HPA) in Kubernetes, what are the best practices of using HPA, especially in the implementation of MaxReplicate, as an example, If I have a cluster with 3 workers nodes running a single app, and setting up the HPA to scale up to 20 pods, but it is a good practice scale pods 3x more than the available nodes? Or scale the pods up to the same quantity of available worker nodes in the cluster as a better approach?</p>
  <p>Thank you in advantage</p>
