Configure Auto Scaling for Azure Virtual Desktop

To configure auto scaling on Azure Virtual Desktop (formerly known as Windows Virtual Desktop), you can follow the steps outlined below. Please note that the instructions assume you have basic knowledge of Azure and Azure Virtual Desktop.

1. Set up an Azure Virtual Desktop environment:

  • Create an Azure Virtual Desktop tenant and host pool.

  • Provision the required virtual machines (session hosts) in the host pool.

  • Ensure the session hosts are properly configured and joined to the Azure Virtual Desktop environment.

2. Configure Azure Monitor:

  • Enable Azure Monitor for your Azure subscription if not already enabled.

  • Set up Log Analytics workspace for collecting monitoring data.

3. Create an Azure Virtual Machine Scale Set (VMSS):

  • In the Azure portal, navigate to the Azure Virtual Desktop host pool resource.

  • Select "Host pools" in the left-hand menu and choose your host pool.

  • Under the "Scaling" section, click on "Enable" next to "Autoscaling."

  • Choose the subscription, resource group, and location for the VMSS.

  • Provide a name for the scale set and specify the number of instances (initial and minimum capacity).

  • Configure the scaling rules based on metrics such as CPU usage, concurrent connections, or custom metrics.

  • Define the maximum and minimum number of instances allowed.

  • Set up the scale-in and scale-out policies as per your requirements.

  • Save the configuration.

4. Configure Azure Monitor Autoscale:

  • In the Azure portal, go to the Azure Virtual Desktop host pool resource.

  • Under the "Scaling" section, click on "Enable" next to "Autoscaling."

  • Select "Azure Monitor" as the scaling mode.

  • Choose the Azure Monitor Autoscale profile to use.

  • Configure the scaling thresholds and rules based on the chosen metrics.

  • Save the configuration.

5. Validate and test the auto scaling:

  • Monitor the performance of your Azure Virtual Desktop environment using Azure Monitor.

  • Ensure that the scaling rules and thresholds are appropriately set to accommodate the workload demands.

  • Test the auto scaling by simulating load on the environment and verifying that the scale set instances are dynamically adjusted based on the configured rules.

By following these steps, you can configure auto scaling for Azure Virtual Desktop using Azure Virtual Machine Scale Sets and Azure Monitor Autoscale. Remember to regularly monitor and adjust your scaling rules to optimize the environment's performance and cost efficiency.
