SQL Server is available under different licensing options, each designed to meet specific customer needs. The number of client access licenses (CALs) required for SQL Server depends on the licensing option you purchased.
 

When installing or purchasing any SQL Server application you should review your Microsoft SQL Server licenses and verify you have the required licensing. Refer to Microsoft or a qualified reseller for additional information on available SQL Server licensing options.

 

Also refer to our SQL Server 2008 Compability Information and SQL Server 2005 Compatibility Information.

Note: For Web applications, Microsoft recommends a separate processor license for each processor used by the SQL Server instance. It includes access for an unlimited number of users or devices to connect to the SQL Server instance from either inside or outside the firewall. You do not need to purchase additional server licenses or client access licenses (CALs) when licensed under the per processor model.
