During the past 40 years, information technology has undergone many revolutions in how applications and data have been delivered to users. Mainframes provided a centralized computation facility where end users consumed resources on a shared basis. Client-server architectures offered flexibility and lowered computing costs while bringing more power to the desktop. Mobile computing introduced the notion of anytime, anywhere application access from a laptop or handheld device. Now cloud computing with virtualization offers a new approach that will enable you to deliver IT services on demand.
Virtualization, in its broadest sense, is the emulation of one of more workstations/servers within a single physical computer. Put simply, virtualization is the emulation of hardware within a software platform. This allows a single computer to take on the role of multiple computers.
There are four main objectives to virtualization, demonstrating the value offered to
organizations:
• Increased use of hardware resources.
• Reduced management and resource costs.
• Improved business flexibility; and
• Improved security and reduced downtime.


Virtualization allows the simulation of hardware via software. For this to occur, some type of virtualization software is required on a physical machine. The most well known virtualization software in use today is VMware. VMware will simulate the hardware resources of an x86 based computer, to create a fully functional virtual machine. An operating system and associated applications can then be installed on this virtual machine, just as would be done on a physical machine. Multiple virtual machines can be installed on a single physical machine, as separate entities. This eliminates any interference between the machines, each operating separately.
