Virtualization Defined
Virtualization ● virt·tual·iz-a-tion ● [vur-choo-uhl-iz-ey-shuhn]
–noun 1. Today’s x86 computer hardware was designed to run a
single operating system and a single application,
leaving most machines vastly underutilized.
Virtualization lets you run multiple virtual machines on
a single physical machine, with each virtual machine
sharing the resources of that one physical computer
across multiple environments. Different virtual
machines can run different operating systems and
multiple applications on the same physical computer.
2. Something only VMware can do well :)

(VMware Server)
• Installs as an
application
• Runs on a host OS
• Depends on OS for
resource management
ESX
• Installs “bare metal”
• Complete HW
management
• Relies on a Linux OS
(Service Console) for
running agents and
scripting
ESXi
• Installs “bare metal”
• Complete HW
management
• Management tasks are
moved outside of the
hypervisor (3rd party
integration via APIs and
CIM; scripting via vRCLI)
