The history of cloud computing goes back to the early 1960s. Computer Scientist, John McCarthy, delivered a speech where he spoke about the possibility of someday having computing power and related applications that could be accessed remotely, similar to electricity, water, and other utilities. The idea was further discussed in Douglas Parkhill's 1966 book, "The Challenge of the Computer Utility." The idea of cloud computing became popular in the late 1960s, but did not become available until the early 2000s.

You can purchase cloud computing hardware from manufacturers like HP and IBM. VM Ware and AT&T also sell cloud computing hardware. PC World is another good place that has a guide and also recommends places to purchase this hardware.

The underlying concept of cloud computing dates back to the 1960s, when John McCarthy opined that "computation may someday be organized as a public utility." Rather than relying on its own hardware to manage IT needs, a business can utilize cloud based computing to access, organize, and secure digital content via entirely web-based software.

There is no sole inventor, it is a business model that utilizes many of the existing modern models, such as the internet, all in addition have no sole, proprietary inventor. Cloud Computing is considered to be an internet-based computing model. The ideology of outsourcing computer hardware has existed even since the 1960s, with John McCarthy who theorized of an eventual computing outsource model.

the present tense of 'compute' will be 'computing'
