Understanding Server CALs

Windows Server 2012 Client Access Licenses (CALs) provide access to Windows Server 2012 R2 or any previous version.
Windows Server 2012 CALs provide access to Windows Server 2008 and 2003. Windows Server 2012 CALs are required to access Windows Server 2012 and Windows Server 2012 R2.

CALs are different from Server Software Licenses.
A server CAL is a license that gives users and devices the right to legally access a server installed with Microsoft server software.

CALs are cost-effective and scalable.
You pay only for the licensing you need. You can adapt your licensing needs by buying CALs as your business grows.
