A development team will deploy and then delete 50 customized virtual machines each week. Thirty VMs run Windows Server 2016 and twenty run Ubuntu Linux. Which Azure service should you recommend to minimize the administrative effort of deploying and removing these VMs?

Azure DevTest Labs is designed for scenarios like this, allowing developers and testers to quickly provision and deprovision environments using templates, policies, and automation. It minimizes administrative effort by providing self-service access to pre-configured VMs and managing their lifecycle, including automatic shutdown and deletion. Azure Reserved Virtual Machine Instances are for cost savings on long-running, consistent workloads, not for temporary, frequently deleted VMs. Azure virtual machine scale sets are for deploying and managing many identical VMs as a single unit, primarily for scaling applications, not for managing diverse, temporary development environments. Microsoft Managed Desktop is a device management service for end-user desktops, unrelated to cloud VM deployment.
