VMware is a virtualization and cloud computing software vendor based in Palo Alto, California. Founded in 1998, VMware is now a subsidiary of Dell Technologies. VMware bases its virtualization technologies on its bare-metal hypervisor ESX/ESXi in x86 architecture. Bare-metal embedded hypervisors can run directly on a server’s hardware without the need of a primary operating system. With VMware server virtualization, a hypervisor is installed on the physical server to allow for multiple virtual machines (VMs) to run on the same physical server. Each VM can run its own operating system, allowing multiple OSes to run on one physical server. All of the VMs on the same physical server share resources, such as networking and RAM.
