Everyone is talking about virtualization these days, yet there seems to be a lot of confusion on what it really is. Mipsmedia has put together this short article hoping to answer many of the questions you might have on the subject and the better part is that we tried to do it in a very colloquial way.
The future in the IT world is revolving around virtualization. Putting it in simple words, virtualization or virtual computing consists in the implementation of a virtual, instead of a physical, version of a server, a network, an operating system or a storage device. Virtualization allows companies to increase efficiency and reduce costs dramatically.
The way it works is that one physical computer performs the job of multiple computers. Every computer in the world, no matter its size, has four capabilities: memory, storage, CPU (processor) and network. Anything with these four capabilities can be virtualized. Most organizations need tens and sometimes hundreds of PCs, servers and laptops with these four components. Here is where virtualization comes in handy. The way virtualization works is that a big piece of hardware (the host) with an incredible power for processing: memory, storage, CPU and network is loaded with a piece of software called abstraction layer (Hypervisor) whose main function is to abstract physical resources and reallocate them more efficiently. Inside of this hardware there are very big files which are the virtual computers (Guests) that perform the tasks we need.
This is highly efficient since it allows companies to save in hardware, energy use and physical space.
To wrap things up, virtualization has revolutionized the IT world in a great way. It is highly convenient since it is possible to have one computer do the work that in the past required the use of many physical devices. You can see now why it has become so important for today’s organizations.
