Virtualization is a proven software technology Virtualization is a proven software technology that is rapidly transforming the IT landscape that is rapidly transforming the IT landscape and fundamentally changing the way that and fundamentally changing the way that people compute.people compute.

Today’s powerful x86 computer hardware was Today’s powerful x86 computer hardware was originally designed to run only a single originally designed to run only a single operating system and a single application, but operating system and a single application, but virtualization breaks that bond, making it virtualization breaks that bond, making it possible to run multiple operating systems and possible to run multiple operating systems and multiple applications on the same computer at multiple applications on the same computer at the same time, increasing the utilization and the same time, increasing the utilization and flexibility of hardware.flexibility of hardware.

How Virtualization works?How Virtualization works?

Virtualization lets you transform Virtualization lets you transform hardware into software. Use software hardware into software. Use software such as VMware to transform or such as VMware to transform or “virtualize” the hardware resources of “virtualize” the hardware resources of an x86-based computer—including the an x86-based computer—including the CPU, RAM, hard disk and network CPU, RAM, hard disk and network controller—to create a fully functional controller—to create a fully functional virtual machinevirtual machine that can run its own that can run its own operating system and applications just operating system and applications just like a “real” computer. like a “real” computer.

What is a Virtual What is a Virtual Machine? Machine?

A virtual machine is a tightly isolated A virtual machine is a tightly isolated software container that can run its software container that can run its own operating systems and own operating systems and applications as if it were a physical applications as if it were a physical computer. A virtual machine behaves computer. A virtual machine behaves exactly like a physical computer and exactly like a physical computer and contains it own virtual (ie, software-contains it own virtual (ie, software-based) CPU, RAM hard disk and based) CPU, RAM hard disk and network interface card (NIC).network interface card (NIC).

An operating system or applications An operating system or applications can’t tell the difference between a can’t tell the difference between a virtual machine and a physical virtual machine and a physical machine. Even the virtual machine machine. Even the virtual machine thinks it is a “real” computer. thinks it is a “real” computer.

Nevertheless, a virtual machine is Nevertheless, a virtual machine is composed entirely of software and composed entirely of software and contains no hardware components contains no hardware components whatsoever. whatsoever.

VMwareVMware approach approach

The The VMwareVMware approach to virtualization approach to virtualization inserts a thin layer of software directly on inserts a thin layer of software directly on the computer hardware or on a host the computer hardware or on a host operating system. This software layer operating system. This software layer creates virtual machines and contains a creates virtual machines and contains a virtual machine monitor or “virtual machine monitor or “hypervisorhypervisor” ” that allocates hardware resources that allocates hardware resources dynamically and transparently so that dynamically and transparently so that multiple operating systems can run multiple operating systems can run concurrently on a single physical concurrently on a single physical computer without even knowing it. computer without even knowing it.

the job of multiple computers, by sharing the the job of multiple computers, by sharing the resources of a single computer across resources of a single computer across multiple environments. multiple environments.

Virtual serversVirtual servers and and virtual desktopsvirtual desktops let you let you host multiple operating systems and multiple host multiple operating systems and multiple applications locally and in remote locations, applications locally and in remote locations, freeing you from physical and geographical freeing you from physical and geographical limitations. limitations.

In addition to energy savings and lower In addition to energy savings and lower capital expenses due to more efficient use of capital expenses due to more efficient use of your hardware resources, you get your hardware resources, you get high availabilityhigh availability of resources, better desktop of resources, better desktop management, increased security, and management, increased security, and improved disaster recovery processes when improved disaster recovery processes when you build a virtual infrastructure.you build a virtual infrastructure.

Benefits Virtualization (2)Benefits Virtualization (2)

Compatibility: Virtual machines are compatible with all standard x86 computers

Isolation: Virtual machines are isolated from each other as if physically separated

Encapsulation: Virtual machines encapsulate a complete computing environment

Hardware independence: Virtual machines run independently of underlying hardware

While a virtual machinevirtual machine represents the physical resources of a single computer, a represents the physical resources of a single computer, a virtual infrastructure represents the physical resources virtual infrastructure represents the physical resources of the entire IT environment, aggregating x86 computers of the entire IT environment, aggregating x86 computers and their attached network and storage into a unified and their attached network and storage into a unified pool of IT resources. pool of IT resources.
