Windows Server Cal User Vs Device

However every user or device that access windows server needs a cal to be compliant.

Windows server cal user vs device.

When you use the per device model a temporary license is issued the first time a device connects to the rd session host. Sql cals are a requirement only for the sql license cal model meaning that if you purchase sql server licenses per core standard core enterprise core you will not need to purchase any additional licenses. Device cals allow access to all instances of a particular server product from a single device a laptop or a desktop computer for example regardless of how many people use that device. The second time that device connects as long as the license server is activated and there are available rds cals the license server issues a permanent rds per device cal.

User cals are the more common licensing option. You either need to buy four device cals to cover those four devices or you need to buy a single user cal to cover that user. Device cals are less common that user cals but they do make sense when multiple employees use the same computer. Cal suites simplify licensing and tracking by reducing the number of licenses that are necessary to access microsoft servers.

Even though user cals are more expensive buying one cal will be much cheaper than buying four. With the user cal you purchase a cal for every user who accesses the server to use services such as file storage or printing regardless of the number of devices they use for that access. A cal gives users or devices the right to access and use services provided by a windows server. Windows server cals do not come with a product key as windows server operating system licenses do and do not need to be registered anywhere in the os.

A client access license cal is not a type of software but rather a license that grants users or devices access to sql server software. The only time the device cal model makes sense is when you have a large number of employees using a limited number of computers.
