How many Azure Virtual Desktop licenses are required when multiple session hosts and file servers are part of the infrastructure?

In the context of Azure Virtual Desktop licensing, it is essential to understand the requirements based on the number of session hosts and how they interact with the infrastructure. Azure Virtual Desktop requires one license per user or device that accesses the service. However, if additional infrastructure components like file servers or session hosts are included, the licensing must accommodate each user accessing these components effectively.

The requirement for a specific number of licenses ties directly to the number of unique users who will be accessing the session hosts. Each user must have a valid license, which might mean that even as multiple session hosts are deployed to balance workloads or provide high availability, the requirement for licenses does not multiply with each host but stays proportional to the unique users.

The answer indicating that 10 licenses are required suggests that a relatively low number of unique users are accessing multiple session hosts and potentially file servers. This implies that while there are multiple session hosts to manage load or redundancy, they do not necessitate additional licenses beyond what is needed for the users accessing them.

In this case, the context surrounding the number of licenses indicates that 10 is deemed sufficient for the infrastructure setup described, which consists of multiple session hosts.
