What is RDS, and why are CALs required?
RDS provides remote access to Windows Server desktops, applications and shared work environments. In older releases the same role was called Terminal Services.
Every user or device that connects to Remote Desktop Services needs an RDS CAL matching that Windows Server version.
CALs are installed and tracked through the Remote Desktop Licensing role in Windows Server.
An RDS CAL does not include the Windows Server operating system, application licenses, hosting or server setup.
Will these RDS CALs work on my server?
Yes, as long as it runs a supported Windows Server with Remote Desktop Services turned on. It does not matter where the server runs.
Your own hardware, or virtual machines on it. Domain or workgroup, either is fine.
A VPS, a dedicated server or a collocated host. You license the server, not the provider.
Azure, or a dedicated host at AWS, Google Cloud or elsewhere. One thing to know: cloud servers are licensed with User CALs.
Which RDS CAL type to buy?
- Your staff connect to the server from more than one device
- You have more devices than people that connect to the server
- Your server is in Azure or another cloud — these are the only option there
- Shifts share the same devices to connect to the server
- You have more people than devices that connect to the server
- You cannot shift to an Active Directory from a workgroup
