Technology advances with every passing day, with an endeavor of coming up with machines that produce more output for less input of resources. Virtualization is one of the products of these aspirations and its invention has left organizations puzzled on whether to be virtualized or not. Perhaps shedding some light on the benefits of virtualization will assist in the decision making process.

First and foremost, it is important to understand what the concept is all about. Virtualization in simple terms means running several operating systems on one server computer. With the help of the xen monitor and the virtualization software, a computer can run several operating system concurrently allowing each system access to its hardware components kike the CPU, RAM, etc.

How virtualization works

You can perform virtualization by installing a layer of software to the computer's hardware or alternatively in the main operating system. The software layer consists of a virtual machine monitor that basically co-ordinates the concurrent execution of the operating system and the allocation of hardware resources. A good example of virtualization is a window based server running a Linux OS on the windows interface.

With this technological invention, various manufacturers have come up with sophisticated virtual machine. Providers of these machines; VMware, IBM, Citrix, Microsoft which has launched its new Hyper-v server developed with cutting edge technology, among others.

Benefits of virtualization

The most basic benefit of virtualization is cost efficiency. Since you are running several operating systems on one computer, you get to save a lot on cash that would otherwise be used on purchasing other physical machines. It also saves on the cost of labor since you don't have to hire many administrators since are only using one physical server.

The other importance of virtualization to your business is that it creates efficiency and agility. With IT specialists having fewer machines to monitor and administrate, their workload is considerably reduced and they are able to concentrate their efforts to increase output. The fact that all virtual servers work independently ensures other servers continue executing normally in the event of one of them crashing.

Important factors to consider when looking for a virtual machine

If you are thinking of purchasing a virtual machine, look for one that has east to use tools for management, resource optimization and allocation, compiling statistics and monitoring activities. You should also select software that is compatible with various platforms for ease in co-ordination between the different operating systems.
