When implementing Azure Site Recovery for an Azure Virtual Desktop infrastructure, what is the minimum number of host pools needed for six session hosts in different availability zones?

When implementing Azure Site Recovery for an Azure Virtual Desktop infrastructure, the minimum number of host pools needed for six session hosts distributed across different availability zones is one.

In this scenario, a host pool is the grouping of session hosts that share the same configuration, and it is feasible to have all six session hosts within a single host pool while utilizing different availability zones to ensure high availability and resiliency. Azure's infrastructure allows you to leverage these availability zones to provide redundancy and minimize downtime without the need for creating multiple host pools.

Using a single host pool simplifies management and provides a cohesive environment for users, allowing sessions to be distributed across the session hosts in different availability zones effectively. This setup ensures that if one availability zone becomes unavailable, the session hosts in the other zones can continue to operate, maintaining service continuity.

Creating additional host pools, while possible, is unnecessary for meeting the requirement of having six session hosts across availability zones, making the single host pool approach the most efficient solution in this case.
