RDS CAL is the license required to access Microsoft VDI/RDS infrastructure. You must obtain RDS CAL for each user or for each device to access the RDS functionality.
For personal or pooled virtual desktop deployments—regardless of VDI architecture used—access to the Windows operating system must be licensed.
*VDI Suite provides RDS CAL (restricted to VDI only) and a System Center Configuration Manager (SCCM) Client Management License (restricted to VMM use only).
