Reduces cost – It is a known fact that, all virtual servers run with 90 percent of utilization versus the servers which are non-virtualized, which only achieve 18 percent utilization ability. So, when the utilization increases, it offers justification to the power consumed and also to the deployed cooling solutions. Thus from the above benefits, an enterprise can save, from their operational costs.
The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
