(UPDATED 6/17/2021 with code for multiple pooled and personal host pools) Azure Virtual Desktop (previously Windows Virtual Desktop (WVD)) has a new option in preview that starts session hosts in a personal or pooled host pool when a user connects. It won’t, however, shut down the session hosts when the user logs out. The script outlined in this video will evaluate all running and available session hosts in a personal or pooled host pool and shut down and deallocate session hosts without an active connection.  Deallocating Session hosts while not in use can save money on compute costs.
