Shared disk in Azure

In this article, we will create a shared disk in Azure.

Shared disk

The shared disk means that the managed disk is attached to multiple virtual machines.

Creating a shared disk

First, create a managed disk. While creating the managed disk, select the appropriate size.

Select the size with the "Max Shares" minimum equal to 2.

Creation of 2 virtual machines

We will create 2 virtual machines for the Windows operating system. While creating the virtual machine, you can attach the existing data disk in both the virtual machines.

Please note that both the virtual machine and disk should have the same region.
