Microsoft Constrained vCPU Virtual Machines available

Effective November 11, 2020, new constrained vCPU capable virtual machines are available from Microsoft. In this type of VM the vCPU count can be constrained to a half or a quarter of the original VM size. This allows customers to reduce the cost of software licensing, while maintaining the same memory, storage, and I/O bandwidth.

For instance, in the E8-4as v4 virtual machine there are 4 active vCPUs and 8 underlying vCPUs, and licensing for SQL Server is constrained to the active vCPU count, with only the operating system cost based on the underlying vCPUs.
