This document discusses the history and modern uses of virtualization. It begins by describing early virtualization techniques and then outlines different types of modern virtualization including CPU, network, server, client/desktop, application, memory, I/O, and OS virtualization. While most companies virtualize 75% or more of their servers, Google runs workloads in virtual machines but uses containers internally. Experts believe virtualization is moving toward a fully software-defined data center where all layers are virtualized and delivered as a service for flexibility. Virtual machines may also be used in virtual reality applications in the future.

However,Google,which acknowledges it runs its
cloud customers' workloads in virtual machines on
its cloud platform,dispenses with virtual machines
in its own internal operations.It is widely regarded
as an experienced user of containers,launching 2
billion a week, without a virtual machine wrapper.
Some firms report they have virtualized 90% of
their servers,or all of those that they plan to. On
average,most firms report 75% or higher
virtualization of their data canter,"illustrating the
high level of penetration," wrote MichaelWarrilow,
research director at Gartner.

7. WHAT LIES AHEAD?
• Experts believe that virtualization is moving toward a
software-based infrastructure that sees virtually every
layer of the data center virtualized and managed by
hypervisors.
• In this environment, those components will be delivered
as a service and automated by software that enables
businesses to be more flexible, agile and responsive to IT
demands.
