A number of key developments permitted the exponential growth of the cloud. The most recent evolution being the development of web 2.0(Term defined below). Furthermore, the Internet played a pivotal role in the gestation of the cloud; since the early days of the Internet limited personal bandwidth only recently has cloud computing become increasingly publicly accessible.
The ARPANET (Advanced Projects Agency Network) a government agency led by J.C.R Licklider in the late sixties introduced the idea of an intergalactic computing network.
Building on McCarthy’s theoriesLicklider furnished much of the early funding and research that can be credited to modern cloud computing. His notions included the idea that everyone in the world will be connected with the accessibility to programs and data at any site remotely.
As a result of the time-share based theory John McCarthy organized multiple PD-1 projects. Of which rooted the nascent of Modern day cloud computing. In the result of the later PD1 project was the first time-share based system on display terminals, used until 1970.
In 1961 John McCarthy, a Professor originally at MIT later Stanford,first suggested the notion of cloud computing in a time-share based computing model.
In his theory he outlined the basis of the modern cloud model. Intended initially as an operating system allowing a user of a computer to interact as if it were in sole control of a computer, not limited to the machine that the current operating system is running on.
Prior to the concept of cloud computing, the information technology landscape looked vastly different from that of the modern IBM, HP and the likes.
Massive supercomputers and mainframes were utilized to create single CPUs in order to aptly process data and information for habitual tasks. Costing millions of dollars and requiring enormous amounts of power. Cloud computing research both directly and indirectly changed the face of information technology completely.
