What is Cloud ?

http://cloudcomputing.sys-con.com/read/612375_p.htm

Prof. Raj Buyya Univ. of Melbourne, Australia: "A Cloud is a type of parallel and distributed system consisting

of a collection of inter-connected and virtualised computers that

are dynamically provisioned and presented as one or moreunified computing resources based on service-levelagreements established through negotiation between theservice provider and consumers.

Keywords: Virtualisation (VMs), Dynamic Provisioning(negotiation and SLAs), and Web 2.0 access interface
