Cloud Computing
History of Cloud Computing
The term “cloud computing” was most probably derived from the diagrams of clouds used to represent the Internet in textbooks. The concept was derived from telecommunications companies who made a radical shift from point-to-point data circuits to Virtual Private Network (VPN) services in the 1990s. By optimizing resource utilization through load balancing, they could get their work done more efficiently and inexpensively. The first time the term was used in its current context was in a 1997 lecture by Ramnath Chellappa where he defined it as a new “computing paradigm where the boundaries of computing will be determined by economic rationale rather than technical limits alone.”
One of the first movers in cloud computing was Salesforce.com, which in 1999 introduced the concept of delivering enterprise applications via a simple website. Amazon was next on the bandwagon, launching Amazon Web Service in 2002. Then came Google Docs in 2006 which really brought cloud computing to the forefront of public consciousness 2006 also saw the introduction of Amazon’s Elastic Compute cloud (EC2) as a commercial web service that allowed small companies and individuals to rent computers on which to run their own computer applications.
This was soon followed by an industry-wide collaboration in 2007 between Google, IBM and a number of universities across the United States. Next came Eucalyptus in 2008, the first open source AWS API compatible platform for deploying private clouds, followed by OpenNebula, the first open source software for deploying private and hybrid clouds.
2009 saw Microsoft’s entry into cloud computing with the launch of Windows Azure in November. Now, suddenly, there were major players jumping on to cloud computing from left, right and center.
Definition of Cloud Computing
Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name
