14 DAY TRIAL // As everyone knows, computers make our work easier these days. It's a heck of a lot easier to just search for some person inside a computerized database than to search for some paper files on a desk or in piles of folders. Bureaucracy is going down fast with new technologies appearing every day.
And now, something even more advanced comes to our attention with VMWare's recently launched IPO. This new invention helps people in a way you could have never thought. Instead of many servers being installed physically into buildings, servers that need as many security measures and that require a lot of administration not to mention that they are to be handled with care by experts so as nothing to crash, VMware comes up with virtualization.
What is this, you ask? Well, what their software actually does is use hardware from different computers that are somehow linked together in order to create a virtual machine. Such a machine does not exist physically, but only in the virtual world. It uses hardware form the computers that have been issued to create it, and rather than one single server hosting a database or something similar, now more computers act as small parts of the big system, each providing a bit of space on their drives and using some of their hardware to properly "power" the virtual machine.
This virtualization is a new but very flexible technology and it enables a powerful and never seen before level of flexibility, allowing servers to be created and moved at the click of a mouse, as NetworkWorld informs us.
This is also great for security reasons - everyone knows that it's a lot easier to take down a single more powerful unit than many little ones that are united. Just think of this - each computer has it's own anti-virus and firewall, so instead of hacking a server, to tear down such a virtual machine, you need to destroy all its components, which is a lot more difficult. Also, if a computer goes down, it's just one PC, and you don't lose access to your whole data, but to just a small part of it. All this sounds quite good and I think virtual machines might just be the solution in the future.
