Per Core: Gives customers a more precise measure of computing power and a more consistent licensing metric, regardless of whether solutions are deployed on physical servers on-premises, or in virtual or cloud.
- Core based licensing is appropriate when customers are unable to count users/devices, have Internet/Extranet workloads or systems that integrate with external facing workloads.
- To license a physical server, customers must license all the cores in the server. Determining the number of licenses needed is done by multiplying the total number of physical cores by the appropriate core factor found in the core factor table. A minimum of 4 core licenses is required for each physical processor on the server. Note: for customers who upgrade to SQL Server 2016, a 20 core limit applies to the software.
