Windows Server / Windows Server CALs: User CALs vs. Device CALs
Windows Server Client Access Licenses (CALs) are a vital component of your organization’s Windows Server licensing. When it comes to CALs, you have two primary choices: User CALs and Device CALs. In this guide, we’ll explore the differences between User CALs and Device CALs to help you determine which CAL type is the right fit for your organization’s needs.
Device CALs are client access licenses assigned to specific devices. Here are the key features of Device CALs:
Device-Based Licensing: Device CALs permit any user of a particular device to access the Windows Server, offering a cost-effective solution.
Ideal for Shared Workstations: Device CALs work best in scenarios where multiple users share a single device, such as in a manufacturing plant.
Device-Centric: Licenses are associated with devices, simplifying management when multiple users access a common device.
In conclusion, the choice between User CALs and Device CALs depends on your organization’s unique requirements and circumstances. By understanding the differences and considering your specific user-device dynamics, you can make an informed decision that optimizes your Windows Server licensing.
