Virtual Computing

What is Virtualisation?

One of the things that virtualization enables is to let one computer do the job of multiple computers, by sharing the resources of a single computer across multiple environments.

Virtual servers and virtual desktops let you host multiple operating systems and multiple applications locally (and in remote locations), providing physical and geographical resilience.

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

How Does Virtualization Work?

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

Multiple virtual machines share hardware resources without interfering with each other so that you can safely run several operating systems and applications at the same time on a single computer.

The VMware Approach to Virtualization

The VMware approach to virtualization inserts a thin layer of software directly on the computer hardware or on a host operating system. This software layer creates virtual machines and contains a virtual machine monitor or “hypervisor” that allocates hardware resources dynamically and transparently so that multiple operating systems can run concurrently on a single physical computer in complete isolation. No virtual machine is in any way aware that other virtual machines exist, even on the same computer.

However, virtualizing a single physical computer is just the beginning. VMware offers a robust virtualization platform that can scale across hundreds of interconnected physical computers and storage devices to form an entire virtual infrastructure.
