Explanation

Two components are needed: (1) An Azure Automation account, which runs the PowerShell-based scaling scripts (Azure Automation runbooks) that monitor session counts and start/deallocate session hosts based on defined thresholds. An Azure Load Balancer is a network-layer component and cannot trigger VM start/stop operations or measure user session counts. (2) Breadth-first load balancing, which distributes new user sessions across all currently running session hosts before filling any single host to capacity. This satisfies the requirement to 'distribute new user sessions across all running session hosts.' Depth-first would concentrate sessions onto one host until it reaches the limit before moving to the next, which contradicts the first requirement. Together, Azure Automation + breadth-first achieves both goals: even distribution and automatic scaling when the 30-user-per-host threshold is crossed.
