Windows

Windows Server is the brand name for a group of server operating systems released by Microsoft. It includes all Windows operating systems branded as "Windows Server", but not any other Microsoft products.  It consists of several families of operating systems, each of which cater to a certain sector of the computing industry. At the heart of the Microsoft Cloud Platform, Windows Server brings the breadth and depth of Microsoft’s experience delivering global-scale cloud services to the datacenter infrastructure.

VMware

VMware virtualizes computing, from the data center to the cloud to mobile devices, to help our customers be more agile, responsive, and profitable. VMware, Inc. is a subsidiary of Dell Technologies, which provides cloud and virtualization software and services, and claims to be the first to successfully virtualize the x86 architecture commercially.

VMware's desktop software runs on Microsoft Windows, Linux, and Mac OS X, while its enterprise software hypervisors for servers, VMware ESX and VMware ESXi, are bare-metal hypervisors that run directly on server hardware without requiring an additional underlying operating system.
