We have a customer who wants to switch from session-based RDS running on a Server 2019 VM to a VDI deployment (Windows Server 2019 Remote Desktop Virtualization Host role), where users would connect to "personal" Windows 10 VMs. We'd remove the session-based implementation and replace with VDI.
Users are all off-site, using their own personal devices (not company owned). There are no thin clients. Users will continue to connect to their existing FortiNet VPN and from there, RDP to their own Windows 10 VM hosted on the server.
Customer already has necessary Server 2019 User and RDS CALs from prior session-based implementation.
We've referenced the April 2020 licensing brief "Licensing Windows desktop operating system for use with virtual machines." On Page 7, our intended scenario is the first one listed. From that, I am assuming that since we cannot ascertain whether a remote user's personal device (the device they connect from) has Software Assurance, and is unlikely to have a VDA subscription, the users will need either an E3 or VDA subscription, but not both.
Some licensing vendors have suggested that both VDA and E3 subscriptions are necessary ...but, the Microsoft brief seems to indicate it's either/or and not both. So, we are unsure what's proper.
Are any licenses required for the Windows 10 VMs themselves (the OS)?
