What does Auto-Scaling in Azure Virtual Desktop help achieve?

Auto-Scaling in Azure Virtual Desktop is designed to optimize resource usage and maintain performance by automatically adjusting the number of active session hosts based on user demand. This means that when there is an increase in the number of users needing access, Auto-Scaling can provision additional session hosts to ensure that users have adequate resources to connect and work without delays or performance issues. Conversely, during times of lower usage, it can scale down the resources to save costs. This dynamic adjustment helps organizations to efficiently manage workloads, ensuring that they are only using the resources they need at any given time.

The other options do not accurately describe the main function of Auto-Scaling within Azure Virtual Desktop. Creating additional storage accounts, improving the performance of individual session hosts, and providing automatic upgrades of virtual machines pertain to different aspects of Azure’s services and management but do not reflect the purpose of Auto-Scaling in response to fluctuating user demand.
