Licensing

Normally, Microsoft licenses its on-premises server products on a per-seat or per-user basis, i.e., the licensing cost depends on how many users or computers use these products. Businesses that install them require to obtain client access licenses (CALs). Windows Server 2012 Essentials and later do not need any CALs. However, this has not always been the case. Earlier versions – Windows Small Business Server (SBS) – had their own types of CAL, and included the user CALs for

, and eventually SQL Server. The SBS CALs cost more than the Windows Server CALs, but less than the sum of separate access licenses for the two or three servers. Windows Small Business Server has the following design restrictions: * Only one computer in the domain can run SBS. The domain supports multiple servers (including additional
