The first benefit everyone sees when looking at virtualization is the increase in server utilization and the decrease in energy costs. Using virtualization, the workloads available on a server are maximized, which is very different from scenarios where hardware uses only a fraction of the computing power. It can reduce the complexity of interaction with various environments and it also offers an easier-to-use management system. Today, working with a large number of virtual machines is not as complicated as interaction with a few of them because of the scalability most tools offer. Also, the time of deployment has really decreased. In a matter of minutes, you can deconfigure and deploy an operating system template or create a virtual environment for a virtual appliance deploy.
One other benefit virtualization brings is flexibility. When a workload is just too big for allocated resources, it can be easily duplicated or moved on another environment that suit its needs better...
