This is a bit of a dated post, but I’m going to discuss virtualization lab configuration for development and experimentation using ESXi hypervisor 6.5.x. It’s particular relevant now as I’ve setup a Kubernetes cluster at home to develop some orchestration scripts and cluster architecture design for scalable applications. This is a much cheaper solution that deploying a cluster into a cloud-based provider. The only resource cost is power which comes in at a significantly cheaper expense than the per-hour provisioning costs of a cloud provider.
