Cloud Computing Timeline
Ideas about computation as a public utility emerged in public discourse and literature.
Mainframe computers first used by businesses for computation; like census data processing, statistics, and financial transaction processing.
Analysts predicted 2009-2010 would see a 19% increase in cloud revenue.
Expected IT spending in 2011 is $3.6 Trillion
Cloud computing accounts for only 2.3% of the global market.
Cloud Computing Precursors
Client-Server Model: Distributed applications which distinguish between providers (or servers), and clients.
Grid Computing: A virtual computer, composed of a cluster of networked, coupled computers (in order to perform larger tasks). Peer-to-Peer: Participants are both suppliers and consumers, using distributed architecture without the need for centralization.
Service-Oriented Computing: Like cloud computing, this service-oriented version implements computing techniques, leveraging software-as-a-service.
The term "cloud computing" was first used by Information Systems Professor, Ramnath Chellappa.
