- 10. Cloud Computing - Definition UC Berkeley RAD Definition Huge Resources The illusion of infinite computing resources available on demand, thereby eliminating the need for Cloud computing users to plan far ahead for provisioning No Commitment The elimination of an up-front commitment by Cloud users, thereby allowing companies to start small and increase hardware resources only when there is an increase in their needs Pay-per-Use The ability to pay for use of computing resources on a short-term basis as needed (e.g. processors by the hour and storage by the day) and release them as needed Source: http://www.eecs.berkeley.edu/Pubs/TechRpts/2009/EECS-2009-28.pdf Page 10
