+This tutorial leverages the [Microsoft Azure](https://azure.microsoft.com) to streamline provisioning of the compute infrastructure required to bootstrap a Kubernetes cluster from the ground up. [Sign up](https://azure.microsoft.com/en-us/free/) for $200 in free credits. In Azure Free Trial there is a limit of 4 Cores available, therefore tutorial instructions must be changed to create 4 nodes instead of 6 (2 controllers and 2 workers).
