Virtualization enables a single user to access multiple physical devices. This paradigm manifests itself as a single computer controlling multiple machines, or one operating system utilizing multiple computers to analyze a database.
This process is about creating an information technology infrastructure that leverages networking and shared physical IT assets to reduce or eliminate the need for physical computing devices dedicated to specialized tasks or systems.
Cloud computing is a process where dynamically scalable and often virtualized resources is provided as a service over the internet. Widespread availability of cheap computing power in business and in homes has created the next advance in information technology.
