Tutorial: Create a host pool to validate service updates

Important

This content applies to Azure Virtual Desktop with Azure Resource Manager Azure Virtual Desktop objects. If you're using Azure Virtual Desktop (classic) without Azure Resource Manager objects, see this article.

Host pools are a collection of one or more identical virtual machines within Azure Virtual Desktop environment. We highly recommend you create a validation host pool where service updates are applied first. Validation host pools let you monitor service updates before the service applies them to your standard or non-validation environment. Without a validation host pool, you may not discover changes that introduce errors, which could result in downtime for users in your standard environment.

To ensure your apps work with the latest updates, the validation host pool should be as similar to host pools in your non-validation environment as possible. Users should connect as frequently to the validation host pool as they do to the standard host pool. If you have automated testing on your host pool, you should include automated testing on the validation host pool.

You can debug issues in the validation host pool with either the diagnostics feature or the Azure Virtual Desktop troubleshooting articles.

Note

We recommend that you leave the validation host pool in place to test all future updates. Validation hostpool should only be used for testing, and not in production environments.

Create your host pool

You can configure any existing pooled or personal host pool to be a validation host pool. You can also create a new host pool to use for validation by following the instructions in any of these articles:

Define your host pool as a validation host pool

To use the Azure portal to configure your validation host pool:

  1. Sign in to the Azure portal.
  2. Search for and select Azure Virtual Desktop.
  3. In the Azure Virtual Desktop page, select Host pools.
  4. Select the name of the host pool you want to edit.
  5. Select Properties.
  6. In the validation environment field, select Yes to enable the validation environment.
  7. Select Save to apply the new settings.

Update schedule

Service updates happen monthly. If there are major issues, critical updates will be provided at a more frequent pace.

If there are any service updates, make sure you have at least a couple of users sign in each day to validate the environment. We recommend you regularly visit our TechCommunity site and follow any posts with WVDUPdate or AVDUpdate to stay informed about service updates.

Next steps

Now that you've created a validation host pool, you can learn how to use Azure Service Health to monitor your Azure Virtual Desktop deployment.
