A description of what VMware ESX is, its features, and a concise description on how it works.

ESX Server is VMware’s flagship enterprise server virtualization platform.  It comes in two versions – ESX Server and ESXi Server where the latter has no service console and is the thinnest version available. ESX Server has many optional features like VMotion and VMHA (both discussed below) and some built-in features like the VMFS file system.  Most end users purchase VMware ESX Server with some set of optional features in a package called VMware Infrastructure. ESX Server is managed by the VMware Infrastructure Client. Its centralized management platform is called Virtual Center.
