SQL Server License requirements are set out in the Microsoft Services Provider Use Rights which can be found on Microsoft’s Web site here:


The number of licenses required when running an Amazon EC2 Windows instance with software licensed using the License Mobility through Software Assurance benefit is based on the instance type and version of SQL Server.

For Microsoft SQL Server 2012 and 2014, the number of SQL Server licenses required by an Amazon EC2 instance is tied to the number of virtual cores used. The following table shows the number of SQL Server core licenses required based on the instance type.
