Virtualization

Operating System Virtualization

It typically allows you to run and install any kind of Operating system like Windows or a Linux on your existing operating system.

It requires a Virtual Machine Manager (VMM) which allows you to install and manage multiple operating systems running simultaneously.

VMware is probably the one of the most used Virtual Machine Manager’s today.

Hardware Virtualization

Hardware virtualization or platform virtualization refers to the creation of a virtual machine that acts like a real computer with an operating system.

Eg: A computer that is running Microsoft Windows may host a virtual machine that looks like a computer with the Ubuntu Linux operating system; Ubuntu-based software can be run on the virtual machine.

There is a hypervisor (VMM) which is used to control processor, memory and other firmware resources.

Network Virtualization

In simple words network virtualization is a process of creating smaller bandwidth channels taken from the hardware and providing it to different virtual servers.

The aim is to provide better network availability to all the virtual servers and of course to cut down cost.

In Network Virtualization, Two (or more) virtual networks can be created within the same physical network belonging to the same IP range also.

Storage Virtualization

There are two types of Storage virtualization

1. Block Virtualization.

2. File Virtualization.

Storage Virtualization

Block Virtualization

In Block Virtualization, multiple storage devices are consolidated, which actually appears as a single physical storage device.

This helps the administrators in many ways such as Load Balancing, optimizing performance and speed.

Storage Virtualization

File Virtualization

File Virtualization, as the name suggests, is the file or directory stored within the hard drive, which is located in a data center.

The file may not be stored within your personal folder; in fact the folder might not even have your own name, it may be located in a data center across the globe.

Desktop Virtualization

Desktop virtualization is a software technology that separates desktop environment and application software.

Virtualized desktops are generally hosted on a remote central server, rather than the hard drive of the personal computer. Because the client-server computing model is used in virtualizing desktops.

Desktop virtualization is also known as client virtualization.
