There’s an updated (May 2024) Power Platform Licensing Guide. The main change is the replacement of the Power Automate Hosted RPA Add-on licence with the full (no prerequisites) Power Automate Hosted Process licence. This license is a superset of the Power Automate Process licence but with the addition of a Microsoft hosted virtual machine and an unattended RPA bot.

Power Automate now supports two hosted RPA scenarios to enable organisations to set up and scale automation. As a reminder, RPA desktop flows can be run either with human interaction (known as “attended”) or without (“unattended”). The new options offer a hosted machine for attended or unattended RPA aimed at users who want to build, test or run automation. Alternatively, there’s a hosted machine group option for unattended RPA which offers automatic scaling and dynamic load balancing. From a licensing perspective, you need to acquire a Hosted RPA Add-on licence for as many bots as you want to run concurrently, and this licence has a prerequisite of either the Power Automate Per User with Attended RPA licence or a Per Flow licence, and costs $215 per bot per month.
