1.1 History of Cloud Computing
Cloud computing first came into concept back in the 1960′s when J.C.R Licklider and John McCarthy proposed that computers may someday be organized in a method that would involve it acting as a public utility. Telecommunication companies began offering VPN (Virtual Private Network) services during the 90′s that were much lower in cost then their at the time offered point-to-point data circuits that provided their services. The cloud symbol represents the difference between the user’s and providers responsibilities. Though they didn’t coined the idea as cloud computing but it created a base for cloud services. They wanted to interconnect all the data and programs through any site/network that can be accessed and managed from anywhere in the world, and also explained how this notion should be used and delivered as public utilities.

Picture 1.1 Picture 2.2 J.C.R Licklider John McCarthy The great idea remained in history pages util it was put in application by In 1999, used a simple website to deliver its enterprise applications to users. Then these applications were delivered over the internet to both mainstream and specialist software that got huge benefits and advantages from these services. Taking an inspiration from this more and more companies shifted their data to cloud servers, but the rate of acceptance was a bit unsatisfactory. The history of cloud computing saw competition only when Amazon started its cloud-based Amazon Web services during 2002 via the Amazon Mechanical Turk, which included human intelligence, computation and storage etc. But, individuals and small companies were not able to take advantages from these applications and Elastic Compute Cloud was launched by Amazon in 2006. This service was completely commercial and anybody can use it as web service. When this service got publicity people started to rent computer because they were able to operate different computer applications. Today sites like Foursquare, HuffingtonPost are hosted on Amazon’s cloud server. How Microsoft could stand watching other companies making long chain of small enterprises and individuals. On October 27, 2008 it prepared to compete with other competitors in cloud computing promotion through Azure Services Platform. Microsoft data centers were established to scale, host and build web applications through the Windows Azure Platform, which made history for Microsoft cloud computing services, which were appreciated on large scale. In 2009, another milestone in the history of cloud computing came when Google plunged into the market to provide enterprises applications based on the browser. Google services like Gmail have text editor, presentations, pdf reader and others to create, read and save files online. Google Apps are entirely based on cloud computing structure. The Google Chrome browser saves all its data to remote cloud server than user computer. 1.2 Definition of Cloud Computing

Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a leased or otherwise metered service over the Internet. Cloud computing is also a marketing term for technologies that provide computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. A parallel to this concept can be drawn with the electricity grid, wherein end-users consume power without needing to understand...
