The concept of pooling resources to extend their use is common to many human endeavors: it is called leveraging in business, fiduciary currency in economy, and virtualization in information technology. To mask the complexity of sharing multiple resources across multiple users, virtualized resources or virtualized users are usually created. Virtualization also delivers transparency to applications that generally expect to interface to a single user or a single resource. Over time, virtualized resources have included virtual memory (first introduced with the famed IBM 360), virtual storage (provided through appliances or embedded in controllers of enterprise arrays), and virtual networks (e.g., VPNs). Server virtualization provides the ability to deploy a discrete number of full-featured application environments called "Virtual machines" or "Guests", on a single, or a few, hardware platforms.
