# Infrastructure # Cloud Infrastructure Provisioning
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 (IaaS).
This lab will walk you through provisioning the compute instances required for running a H/A Kubernetes cluster. A total of 9 virtual machines will be created.
After completing this guide you should have the following compute instances:
```
gcloud compute instances list
```

> All machines will be provisioned with fixed private IP addresses to simplify the bootstrap process.
To make our Kubernetes control plane remotely accessable a public IP address will be provisioned and assigned to a Load Balancer that will sit in front of the 3 Kubernetes controllers.
## Create the Kubernetes Public IP Address
Create a public IP address that will be used by remote clients to connect to the Kubernetes control plane:
``` ```
gcloud compute addresses create kubernetes gcloud compute addresses create kubernetes
``` ```
``` ```
146.148.34.151 gcloud compute addresses list
