This week I chose to write about virtualization, because while listening to the lectures, I thought it was a very interesting concept, but I didn't quite understand it. However, after researching many websites, I feel like I have a better grasp on the subject.
The technical definition of virtualization is the creation of a virtual (rather than actual) version of something, such as an operating system, a server, a storage device, or network resources. It can be viewed as part of an overall trend in enterprise IT that includes autonomic computing, a scenario in which the IT environment will be able to manage itself based on perceived activity, and utility computing, in which computer processing power is seen as a utility that clients can pay for only as needed. Most often the goal of virtualization is to centralize administrative tasks while improving scalability and work loads.
Some other advantages to virtualization include server consolidation, reduced power and cooling, green computing, and high availability and disaster recovery. While virtualization technology is most popular in the server world, virtualization technology is also being used in data storage such as Storage Area Networks, and inside of operating systems such as Windows Server 2008 with Hyper-V.
