Configure autoscaling for a Windows 10 Enterprise multi-session host pool to (a) distribute new sessions across all running hosts and (b) automatically add a host when concurrent sessions exceed 30 per host. What should you include?

To achieve the desired autoscaling and session distribution, you need an Azure Automation account and the breadth-first load balancing algorithm. Azure Automation accounts are used to implement autoscaling for Azure Virtual Desktop host pools, allowing you to automatically add or remove hosts based on predefined triggers like session limits. The breadth-first load balancing algorithm distributes new user sessions evenly across all available session hosts in the host pool until each host reaches its session limit. This ensures that new sessions are spread out, preventing any single host from becoming overloaded prematurely. An Azure load balancer is not directly used for session host load balancing within an Azure Virtual Desktop host pool; the service itself handles this. The depth-first algorithm fills the first available host to its session limit before moving to the next, which doesn't meet the requirement of distributing new sessions across all running hosts.
