To storing and accessing data and programs
over the Internet instead of your computer's
hard drive.

Process of cloud computing

5. The origin of the term cloud computing is unclear.
The actual term "cloud" borrows from telephony. Telecommunications
companies, who until the 1990s primarily offered point-to-point data circuits, began
offering Virtual Private Network (VPN) services with a comparable quality of service
but at a much lower cost.
They used the cloud symbol to mark the point between the infrastructure that was the
responsibility of the provider, and where the user took over. Cloud computing extends
this boundary to cover servers as well as the network infrastructure. The first scholarly
use of the term “cloud computing” was in a 1997 lecture by Ramnath Chellappa.

6. Let's say your company required 13 physical systems to run your sites and
applications. With virtualization, you can take those 13 distinct systems and split them
up between two physical nodes. Obviously, this kind of environment saves on
infrastructure costs and minimizes the amount of actual hardware you would need to
meet your company's needs.

7. How Cloud Computing Work

8. How does Cloud Computing Work
Cloud computing is to apply traditional supercomputing, or high-performance
computing power, normally used by military and research facilities, to perform tens of
trillions of computations per second, in consumer-oriented applications such as
financial portfolios, to deliver personalized information, to provide data storage or to
power large, immersive computer games.
It seems that everyone with a computer spends a lot of time acquiring data and then
trying to find a way to store it.
•On the surface, cloud storage has several advantages over traditional data storage.
For example, if you store your data on a cloud storage system, you'll be able to get to
that data from any location that has Internet access. You wouldn't need to carry
around a physical storage device or use the same computer to save and retrieve your
information. With the right storage system, you could even allow other people to
access the data, turning a personal project into a collaborative effort.
