Virtualization means creation of virtual things like virtual storage device, server or network resources. Storage virtualization is done by pooling of different physical storage from multiple networks to form a single storage device. Server virtualization is done by masking of server resources. Network virtualization is done by combining the available resources in a network and by splitting the available bandwidth in to channels each of which are independent of other and each can be assigned to a particular server. Basically virtualization is done to utilize and manage the available resource properly. Server virtualization gives organizations the flexibility they need to respond the changing business requirement. Virtual servers reduce the physical resources. This gives organizations the ability to extend protection to additional applications and data with the same or fewer resources.

While doing research on virtualization i came across a site which provides virtualization solutions.

Server virtualization is partitioning off your single server into multiple separate environments known as virtual machines. Instead of having one physical server that runs all your applications, you can use software to divide the single server into many virtual machines within the server, each one separate and isolated from one another and each one dedicated to specific applications of your choice.

Think of it as taking a large room and partitioning it off into smaller rooms where specific actions can take place without hindering one another, or imageine a large loft with 10 roommates. Using the concept of server virtualization, each roommate would have his or her separate room within the loft, or their own virtual machines, where they can mind their own business and not bother each other.

Why You Want It

Divvying up your single server into multiple virtual servers can be helpful for a number of reasons. Webopedia notes it is a common way to offer cost-effective Web Hosting services for multiple users. Rather than each user needing a separate computer of his or her own, all can share one large server. PC Magazine says cloud computing and enterprises also often take advantage of virtual servers.

Saving money and space are prime benefits. You only need to service, update, operate, maintain and purchase a single server instead of multiple machines. Consolidating the resources into a single machine requires less storage space and less of an investment. According to dinCloud, virtual servers are the best solution for small and medium enterprises as companies can not only reduce their cost of purchasing costly IT infrastructure but at the same time improve accessibility to retrieve and update data from a single access point.

Because each virtual machine can employ its own operating system independent of the others, you can easily reboot, update or remove one of the operating systems without affecting any of the others. If one OS crashes or goes down, it has no bearing on all the other OS that can remain up and running with no issues.

You also have the option of easily moving or copying any of the virtual machines to another virtual machine, a process PC Magazine notes is known as "live migration." This allows you to move an OS to better balance the load or increase the capacity as often and seamlessly as needed.

Need more information on server virtualization?

Server virtualization is a technology that allows one physical server to run multiple virtual servers, known as virtual machines (VMs). Each VM runs its own operating system and applications, as if it were a separate physical server. This helps maximize the use of server resources, improves scalability and flexibility, and reduces hardware costs. The virtualization software, known as a hypervisor, creates and manages the virtual servers.

What is virtualization technology used for?

The main goal of virtualization technology is to provide a more efficient use of server resources. Often a server will be sitting there doing pretty much nothing, using less than 5% of resources, but still eating up full power. With virtualization you capture all that wasted resource by running numerous server instances on the same hardware so a single server could act like 15, 20 or more servers.
