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 2008 R2 Standard, the number of SQL Server processor licenses required for an Amazon EC2 instance is tied to the number of virtual processors used. For Microsoft SQL Server 2012, the number of SQL Server core 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 processor or core licenses required required based on the instance type.

Instance Type	Number of Virtual Cores	Number of SQL 2008 Standard or Enterprise Processor Licenses	Number of SQL 2012 Standard or Enterprise Core Licenses
m1.small	1	1	4
m1.large	2	1	4
m1.xlarge	4	2	4
m2.xlarge	2	1	4
m2.2xlarge	4	1	4
