26. The Cloud:
Rows and floes of angel hair
And ice cream castles in the air
And feather canyons ev'rywhere
-Joni Mitchell
The term "cloud" is used as a metaphor for the Internet, based on the
cloud drawing used in the past to represent the telephone network,
and later to depict the Internet in computer network diagrams as an
abstraction of the underlying infrastructure it represents.
Cloud computing provides 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.
