Virtual Infrastructure Manager

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.

The VIM coordinates the server hardware so that virtual server instances can be created from the most expedient underlying physical server. It can be used to manage a range of virtual IT resources across multiple physical servers, and provides for centralized administration of virtualized resources including creating, storing, backing up, patching and monitoring.

As an example, a VIM can create and manage multiple instances of a hypervisor across different physical servers, and can move a virtual server from one physical server to another.

Figure 1 shows a resource management system encompassing a VIM platform and a virtual machine image repository. The VIM may have additional repositories, including one dedicated to storing operational data.
