Scalability is a desirable attribute of a system or process. Poor scalability can result in poor system performance. Kubernetes is very much flexible, dynamic but when it comes to scaling, we encountered few challenges in application pod scaling which ended up having an adverse impact on application performance. In this blog, we will walk through the steps to overprovision a k8s cluster for scaling and failover.

Let’s say we have a Kubernetes cluster running with X number of worker-nodes. All nodes in the cluster are running at their full capacity, meaning there is no space left on any of the…
