The document discusses the definition and history of cloud computing. It notes that the term "cloud" originated from depictions of computer networks as stylized clouds in diagrams. The National Institute of Standards and Technology (NIST) provides a widely cited definition of cloud computing that describes its essential characteristics, service models, and deployment models. The document then discusses the benefits, drivers, inhibitors and taxonomy of cloud computing, as well as market trends and the declining cost of data storage over time.

Cloud in the Internet era ….
The origin of the term cloud computing is obscure, but it appears
to derive from the practice of using drawings of stylized clouds to
denote networks in diagrams of computing and communications
systems. The word cloud is used as a metaphor for the Internet,
based on the standardized use of a cloud-like shape to denote a
network on telephony schematics and later to depict the Internet
in computer network diagrams as an abstraction of the underlying
infrastructure it represents. The cloud symbol was used to
represent the Internet as early as 1994
