CLOUD COMPUTING

 Cloud computing is computing in which large groups of remote servers are networked to allow centralized data storage and online access to computer services or resources. Clouds can be classified as public, private or hybrid  It focuses on maximizing the effectiveness of the shared resources  cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance

Service models Cloud computing providers offer their services according to several fundamental models

 Large-scale mainframe computers were seen as the future of computing, and became available in academia and corporations, accessible via thin clients/terminal computers, often referred to as "static terminals", because they were used for communications but had no internal processing capacitiesmainframe computersterminal

 Telecommunications companies, who previously offered primarily dedicated point- to-point data circuits, began offering virtual private network (VPN) services with comparable quality of servicevirtual private network  They began to use the cloud symbol to denote the demarcation point between what the provider was responsible for and what users were responsible for  Cloud computing extends this boundary to cover all servers as well as the network infrastructure

Since 2000  In early 2008, Eucalyptus became the first open- source, AWS API-compatible platform for deploying private clouds. In early 2008, OpenNebula, enhanced in the RESERVOIR European Commission-funded project, became the first open-source software for deploying private and hybrid clouds, and for the federation of cloudsEucalyptusAWSOpenNebula  In July 2010, Rackspace Hosting and NASA jointly launched an open-source cloud-software initiative known as OpenStackRackspace HostingNASAOpenStack  On March 1, 2011, IBM announced the IBM SmartCloud framework to support Smarter PlanetIBM SmartCloudSmarter Planet  On June 7, 2012, Oracle announced the Oracle CloudOracle Cloud

 According to Gartner's Hype cycle, cloud computing has reached a maturity that leads it into a productive phaseHype cycle  The major Cloud technology developers continue to invest billions a year in Cloud R&D, Microsoft for example committed 90% of its $9.6bn R&D budget to Cloud
