Which RDS CALs 2019 licence is right for me?

Windows Server operating system licences only cover the server’s operation on the physical machine of the licence owner. They do not provide authorization for users or devices to connect.

To enable users or devices to connect and utilize specific services, additional licences are required.

A User-CAL authorizes a person to access the server, allowing connection from multiple endpoints as the licence is tied to the user, not the device. Conversely, a Device-CAL permits a device to access the server, meaning users of this device do not need individual User-CALs.

Which is ideal for my business?

Your choice depends on whether you have more employees or devices and your operational setup, including whether staff need remote or single-location access.

For instance:

• If your number of employees is lower than the number of devices, opt for User-CALs, especially if employees use multiple devices to connect to the server.
• If you have fewer devices than users, Device-CALs may be more suitable, especially if staff are stationed at one location but share devices across shifts.

RDS CALs User Licence

Using the RDS CALs user licence allows each user to connect to a Remote Desktop Session Host from any number of devices. The licensing server distributes licences from the available pool. It’s crucial to maintain valid licences and ensure compliance with Remote Desktop Services licensing terms.

For many businesses, the user licence is the most cost-effective solution, as employees often access servers from multiple devices. For example, an employee accessing their email on various devices throughout the week only needs one RDS CALs user licence, whereas using multiple device licences would require separate licences for each device.

RDS CALs Device Licence

In the per-device model, a temporary licence is issued on the initial connection to the Remote Desktop Session Host. On subsequent connections, the licensing server provides a permanent RDS device CAL, given that the server is activated and licences are available.

This model is ideal for environments with numerous employees using a few shared computers, such as kiosks, shared PCs for maintenance teams, or businesses with overlapping shifts.
