Understanding Windows Server CAL

Greetings, Dev! As a software developer, you are likely familiar with Windows Server CAL or Client Access License. It is a licensing method that allows users and devices to access a Windows Server instance, which is essential for businesses that rely on Microsoft’s server products for their operations.

What is a Windows Server CAL?

A Windows Server CAL is a legal requirement for every user or device that accesses Windows Server. The license is tied to a user or device and allows them to access various features, including file sharing, directory services, and printing services. For instance, if you have 100 employees who access Windows Server, you would need to purchase 100 Windows Server CALs, regardless of whether they use one or multiple devices to access the server.

Note: It is important to note that a Windows Server CAL only allows access to the server instance and does not include the server software itself. You will need to purchase the server software separately.

Types of Windows Server CAL

There are two primary types of Windows Server CAL: User CAL and Device CAL. Choosing between the two depends on the needs of your organization.

User CAL

A User CAL is assigned to a specific user and enables them to access the Windows Server instance from any device. This type of CAL is suitable for businesses that allow their employees to use multiple devices, such as desktops, laptops, and mobile devices, to access the server.

Device CAL

A Device CAL is assigned to a specific device, such as a desktop or laptop, and enables any user who uses that device to access the Windows Server instance. This type of CAL is suitable for businesses that have multiple employees who share devices to access the server.

How to Purchase Windows Server CAL

You can purchase Windows Server CAL through various channels, including Microsoft Volume Licensing, original equipment manufacturers (OEMs), and retail stores. The cost of CALs varies depending on the licensing model, the number of users or devices, and the type of CAL you choose.

Microsoft Volume Licensing

If you have a large number of users or devices that need access to Windows Server, Microsoft Volume Licensing is the best option. It allows you to purchase licenses in bulk, which can lead to cost savings. You can choose between Open, Select, and Enterprise agreements, depending on your needs.

OEMs

If you purchase a server from an original equipment manufacturer (OEM), such as Dell or HP, you can typically purchase CALs directly from them. This option is suitable for small businesses that do not require a large number of licenses.

Retail Stores

If you only need a few CALs, you can purchase them from retail stores that sell Microsoft software. This option is suitable for small businesses that need to purchase licenses on an as-needed basis.
