2011 ended with the popularization of an idea: bringing VMs (virtual machines) onto the cloud. Recent years have seen great advancements in both cloud computing and virtualization.

The term virtual machine essentially describes sharing the resources of one single physical computer into various computers within itself. VMware and virtual box are commonly used virtual systems on desktops. Cloud computing effectively stands for many computers pretending to be one computing environment. Obviously, cloud computing would have many virtualized systems to maximize resources.
