Many administrative tasks can be performed more easily using virtual servers as opposed to using their physical counterparts. Modern virtualization software provides several advanced management functions that can automate administration tasks and reduce the overall operational burden on virtualized IT resources.
Virtualized IT resource management is often supported by virtualization infrastructure management (VIM) tools that collectively manage virtual IT resources and rely on a centralized management module, otherwise known as a controller, that runs on a dedicated computer. VIMs are commonly encompassed by the resource management system mechanism.
