Azure DevTest Labs : Azure managed identities to deploy lab environments
Azure managed identities to deploy lab environments As a lab owner, you can now use a user assigned managed identity to deploy environments in a lab. This feature is helpful in scenarios where the environment contains or has references to Azure resources such as key vaults, shared image galleries, and networks that are external to the environment’s resource group. It enables creation of sandbox environments that aren’t limited to the resource group of that environment only.
