VMware ESX is VMware’s enterprise
platform. The platform is available in two versions -- ESX Server and ESXi Server. VMware ESX and ESXi can be deployed as part of the VMware infrastructure (vSphere or VMware View) to enable centralized management for data center
applications and enterprise desktops. One main feature of the enterprise server virtualization platform
is that it allows users to contain server sprawl by running software applications in virtual machines on fewer physical servers.
