Adding Our Existing Azure Virtual Machine To High Availability Set

In our previous article, we have learned Configuring Virtual Machines Scale Sets in Azure. You can read that article from this link here. In this article, we will learn how to add our existing Azure Virtual Machine to High Availability Set.

We have already created an Availability Set named “iisweb” under the “Blog” Resource Group. There are no Virtual Machines under the iisweb Availability Set.

We have already created two virtual machines running under the Blog Resource group; those are -

Download the PowerShell script named “Set-ARmVmAvailabilitySet.ps1” to your local machine. Open the PowerShell and run the script.

Enter the VmName, AvalabilitySetName, and ResourceGroup Name and hit Enter. In this demo, our instance names are;

When you hit the Enter key, the "Sign in to Microsoft Azure" prompt asks for Azure login credentials. So, enter your username and password.

Now, we can verify that our Virtual Machine named “Web1” has been successfully added to our “iisweb” Availability Set.

Again, repeat the same process to add our second virtual machine named “Web2” in the same Availability Set named “iisweb”.

Now, we can verify that our Virtual Machine “Web1” is running under the iisweb Availability Set, and the second Virtual machine “Web2” is being created.

Now, both the Virtual Machines are successfully added to our existing High Availability Set.

In this demo, we have learned how to add our existing virtual machine to a High Availability Set in Microsoft Azure. If you have any questions, feel free to comment under the article.
