virtualization at a Glance
· In corporate IT environments, servers are needed to do many jobs. Each machine is tasked to do only a single job, and often many servers are given the same job. This is done to prevent hardware and software problems on one machine from endangering several systems. There is a downside with this arrangement, though, in that server hardware can be very expensive, and many servers do not utilize their full resources. When this is the case, server virtualization can provide a way to reduce hardware costs while still providing protection against software failure.
