## Overview

In this section we cover how to launch Ray clusters on Cloud VMs. Ray ships with built-in support
for launching AWS and GCP clusters, and also has community-maintained integrations for Azure, Aliyun and vSphere.
Each Ray cluster consists of a head node and a collection of worker nodes. Optional
[autoscaling](vms-autoscaling) support allows the Ray cluster to be sized according to the
requirements of your Ray workload, adding and removing worker nodes as needed. Ray supports
clusters composed of multiple heterogeneous compute nodes (including GPU nodes).

Concretely, you will learn how to:

- Set up and configure Ray in public clouds
- Deploy applications and monitor your cluster
