# Prerequisites # Prerequisites
This tutorial can be followed using either Google Cloud Platform or Microsoft Azure. Any sections where the commands to be entered are different based on the selected platform will either be captioned ```gcloud``` or ```az```, depending on the platform that the command applies to.
## Google Cloud Platform ## Google Cloud Platform
This tutorial leverages the [Google Cloud Platform](https://cloud.google.com/) to streamline provisioning of the compute infrastructure required to bootstrap a Kubernetes cluster from the ground up. [Sign up](https://cloud.google.com/free/) for $300 in free credits.

## Networking ## Networking
The Kubernetes [networking model](https://kubernetes.io/docs/concepts/cluster-administration/networking/#kubernetes-model) assumes a flat network in which containers and nodes can communicate with each other. In cases where this is not desired [network policies](https://kubernetes.io/docs/concepts/services-networking/network-policies/) can limit how groups of containers are allowed to communicate with each other and external network endpoints.
