VMware Infrastructure is a collection of virtualization products from VMware. Virtualization is an abstraction layer that decouples hardware from operating systems. The VMware Infrastructure suite allows enterprises to optimize and manage their IT infrastructure through virtualization as an integrated offering.
VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware, a subsidiary of Broadcom, for deploying and serving virtual computers.As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel.
Logical diagram of full virtualization. Full virtualization employs techniques that pools physical computer resources into one or more instances; each running a virtual environment where any software or operating system capable of execution on the raw hardware can be run in the virtual machine.
VMware vSphere (formerly VMware Infrastructure 4) is VMware's cloud computing virtualization platform. [ 2 ] It includes vCenter Configuration Manager, as well as vCenter Application Discovery Manager, and the ability of vMotion to move more than one virtual machine at a time from one host server to another.

Founded in 2009 under the name Acadia , it was originally a joint venture between EMC and Cisco Systems , with additional investments by Intel and EMC subsidiary VMware .
vCenter Server Appliance (VCSA) is the centralized management utility for VMware, and is used to manage virtual machines, multiple ESXi hosts, and all dependent components from a single centralized location. VMware vMotion and svMotion require the use of vCenter and ESXi hosts.
Process virtual machines are designed to execute computer programs in a platform-independent environment. Some virtual machine emulators, such as QEMU and video game console emulators , are designed to also emulate (or "virtually imitate") different system architectures, thus allowing execution of software applications and operating systems ...
Even the simple CMS could be run in a threaded environment (LISTSERV, TRICKLE). z/VM is the current version of VM, and is used to support hundreds or thousands of virtual machines on a given mainframe. Some installations use Linux on IBM Z to run Web servers, where Linux runs as the operating system within many virtual machines.
