What is Virtualization?

VMware provides hardware virtualization that presents a complete x86

platform to the virtual machineAllows multiple applications to run in isolation within virtual machines

on the same physical machine

Virtualization provides direct access to the hardware resources to give

you much greater performance than software emulation

Tangible:

Cost savings (Servers, Space, Power, Cooling)

Improve asset utilization

Allow faster resource deployment

Reduce datacenter costs by reducing your physical

infrastructure and improving your server to admin

ratio

Improve desktop manageability and security

Better management

Intangible: Business Continuity Disaster Recovery Easy to manage

Strategic Benefits:

Virtualization helps them treat their internal

infrastructure as a service rather than a lot of

hardware means
