“Cloud computing is a style of computing where massively
scalable IT-related capabilities are provided as a service
across the Internet to multiple external customers”
“Cloud computing: A pool of abstracted, highly scalable, and
managed infrastructure capable of hosting end-customer
applications and billed by consumption”
“Cloud computing is Web-based processing, whereby shared
resources, software, and information are provided to computers and
other devices (such as smart phones) on demand over the Internet.”

History
when John McCarthy wrote that “computation may someday be
organized as a public utility.” Then, grid computing, a concept that
originated in the early 1990s as an idea for making computer power as
easy to access as an electric power grid also contributed to cloud
computing.
The general idea behind the technology dates back to the 1960s,

One of the first movers in cloud computing was Salesforce.com,
which in 1999 introduced the concept of delivering enterprise
applications via a simple website.
In 2002 Amazon started Amazon Web Services, providing
services like storage, computation and even human intelligence.
The year 2006 also saw the introduction of Amazon’s Elastic Compute cloud (EC2) as a commercial
web service that allowed small companies and individuals to rent computers on which to run their
own computer applications.

Virtualization
In hardware virtualization, the host machine is the actual machine on which
the virtualization takes place, and the guest machine is the virtual machine.
The words host and guest are used to distinguish the software that runs on
the actual machine from the software that runs on the virtual machine. The
software or firmware that creates a virtual machine on the host hardware is
called a hypervisor or Virtual Machine Manager.

Virtualization
Desktop virtualization (sometimes called client virtualization) is a concept
which separates a personal computer desktop environment from a
physical machine using the client–server model of computing.
