This look at Remote Desktop Services Virtualization (RDS-V). RDS-V also referred to as Virtual Desktop Infrastructure (VDI) provides remote desktop access to managed desktop environments hosted in Hyper-V on Windows Server 2008 R2. RDS-V uses Remote Desktop Connection Broker to determine where user’s redirected. If a user’s assigned and requests a personal virtual desktop, RD Connection Broker redirects user to this virtual machine. If VM is not turned on, RD Virtualization turns on VM and then connects user. If user is connecting to a shared virtual pool, then RD Connection Broker checks to see if user already has a connected session in pool.
