In this section, you are going to complete some exercises that will teach you how to increase the availability and reliability of your virtual machine solutions on Azure using availability sets.

Availability sets ensure that the virtual machines you deploy in Azure are distributed across multiple isolated hardware nodes in a cluster. Deploying multiple virtual machines in an availability set ensures that if a hardware or software failure within Azure happens, only a subset of the virtual machines are impacted and your overall solution remains available and operational.

In this section, you will learn how to:

• Create an availability set
• Create a VM in an availability set
• Check available VM sizes
• Check Azure Advisor

When you reach the end of these exercises, you should know how to deploy the basic HA functionality that comes with availability sets.
