Description

SQL Server User Client Access Licenses (User CALs) represent a licensing method in Microsoft SQL Server that allows a specific user to access the server, independent of the device they use. Below is a detailed explanation:

1. What Are User CALs?

• A User CAL permits an individual user to connect to SQL Server.
• The license is assigned to a user, not to a device.

2. How Do They Function?

• A User CAL lets the licensed user access SQL Server from any device, such as a computer, tablet, smartphone, or laptop.
• It’s particularly beneficial for users who rely on multiple devices to connect to the server.

3. When Are User CALs the Right Choice?

• Ideal for organizations with more devices than users since a single license covers access from multiple devices for one user.
• Useful for employees who frequently switch between devices while maintaining uninterrupted server access.

4. User CALs vs. Device CALs

• User CALs are tied to an individual user, while Device CALs are assigned to a specific device.
• Device CALs are better suited for environments where several users share access to a single device, such as a shared workstation in a factory or kiosk.

5. Key Points to Remember

• User CALs are commonly applied in SQL Server editions using the Server + CAL licensing model instead of per-core licensing.
• Every user connecting to the server must have a User CAL.
• These licenses provide access rights but do not include the SQL Server software itself.

6. Examples of Usage

• A sales executive who accesses SQL Server from an office desktop, a travel laptop, and a mobile device benefits from a User CAL.
• A remote worker connecting from multiple personal devices can efficiently use a User CAL.

Understanding how User CALs work is crucial for ensuring licensing compliance while optimizing costs in SQL Server deployments.
