Cloud computing involves storing and accessing data and programs over the internet instead of on local hard drives, evolving from historical telecommunication practices. It offers advantages like reduced infrastructure and maintenance costs, increased computing power, and unlimited storage, while requiring constant high-speed internet and raising security concerns. The concept originated from the term used by telecom companies in the 1990s and gained scholarly attention in 1997.

2. What is Cloud Computing?
To storing and accessing data and
programs over the Internet instead of
your computer's hard drive.

5. History of Cloud Computing
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.
