Server virtualization for commodity servers is one of the most rapidly adopted technologies of all times. The traditional and less effective “one physical server, one application” approach is giving way to pools of resources being shared among virtual servers. Not only will you be able to save resource in terms of power, cooling and floor space in the data center, you can also save money by avoiding some of the over-provisioning that accompanies a one physical server, one application strategy. And virtualization offers a more flexible solution where resources can be redistributed in accordance with shifting demands.
