Microsoft released a new licensing update for products that are licensed under the Per Core licensing method such as Microsoft SQL and Microsoft BizTalk. Microsoft discontinued the Core Factor when calculating the licenses required for these products. In the new Services Provider Use Rights, you calculate the number of cores on the physical server or the number of virtual cores on the VM. You just need to report a minimum of 4 cores per VM/physical core. You can find below the explanation from the SPUR Document.

For Products under the Per Core License Model, Customer must choose either licensing by Physical Core on a Server or licensing by Individual Virtual OSE. The terms for each are set forth below.

Server Licenses (per core) – Licensing by Physical Core on a Server
1. Customer may use the server software on a Licensed Server, provided it acquires sufficient Licenses as described below.
2. The number of Licenses required equals the number of Physical Cores on the Licensed Server subject to a minimum of four Licenses per Physical Processor.
3. For enterprise editions, Customer may use any number of Running Instances of the server software on the Licensed Server in the Physical OSE and/or any number of Virtual OSEs.
4. For other editions Customer may use any number of Running Instances of the server software only in the Physical OSE on the Licensed Server.

Server Licenses (per core) – Licensing by Individual Virtual OSE
1. Customer may use any number of Running Instances of the server software in any Virtual OSE on the Licensed Server, provided it acquires sufficient Licenses as described below.
2. The number of Licenses required equals the number of Virtual Cores in the Virtual OSE, subject to a minimum of four License per Virtual OSE.
3. If any Virtual Core is at any time mapped to more than one Hardware Thread, Customer needs a License for each Hardware Thread to which it is mapped.
