ServerCAL

ServerCAL, or Server Client Access License, is a licensing model used by Microsoft for its server software. It allows organizations to purchase a license that enables a specified number of users to access the server. This model is particularly relevant for environments where multiple users need to connect to a server, such as file servers, application servers, or terminal servers.

ServerCALs are typically used in conjunction with a Server License, which covers the cost of the server software itself. The number of ServerCALs required depends on the number of users who will be accessing the server. For example, if a server is being used by 100 users, the organization would need to purchase 100 ServerCALs.

There are different types of ServerCALs, including Device CALs and User CALs. Device CALs are assigned to devices, allowing any user on that device to access the server. User CALs, on the other hand, are assigned to individual users, allowing them to access the server from any device.

ServerCALs are a flexible and cost-effective way for organizations to manage server access. They provide a clear understanding of licensing costs and can help prevent unauthorized access to server resources. However, it's important for organizations to accurately assess their user base to avoid overpaying or underpaying for ServerCALs.
