+Kubernetes can be installed just about anywhere physical or virtual machines can be run. In this lab we are going to focus on [Google Cloud Platform](https://cloud.google.com/), [Amazon Web Services](https://aws.amazon.com) and [Microsoft Azure](https://azure.com).
 
 This lab will walk you through provisioning the compute instances required for running a H/A Kubernetes cluster.
