Hyper-V

Microsoft’s hypervisor, available with Windows 10 (Pro, Enterprise, and Education) and with all editions Windows Server 2016 or older.

A large advantage of this hypervisor is how it comes available with Windows, requiring no additional software or licensing. However competing virtualization platforms are typically chosen over Hyper-V for commercial applications, though Hyper-V does have numerous commercial deployments. Most certain a version of Hyper-V is used to power the Azure cloud.
