What is CLOUD COMPUTING ??

Cloud computing means storing and accessing data and programs
over the Internet instead of your computer’s hard drive. The
cloud is just a metaphor for the Internet. It goes back to the
days of flowcharts and presentations that would represent the
gigantic server-farm infrastructure of the Internet as nothing
but a puffy, white cumulonimbus cloud, accepting connections
and doling out information as it floats.

Cloud computing, often referred to as simply “the cloud,” is
the delivery of on-demand computing resources—everything from
applications to data centres—over the Internet on a pay-for use basis.

Business applications are moving to the cloud. It’s not just a
fad—the shift from traditional software models to the Internet
has steadily gained momentum over the last 10 years. Looking
ahead, the next decade of cloud computing promises new ways to
collaborate everywhere, through mobile devices.

 CLOUD COMPUTING

  Software as a service (SaaS)

Cloud-based applications—or software as a service (SaaS)—run on
distant computers “in the cloud” that are owned and operated by
others and that connect to users’ computers via the Internet
and, usually, a web browser.

  Platform as a service (PaaS)

Platform as a service provides a cloud-based environment with
everything required to support the complete lifecycle of
building and delivering web-based (cloud) applications—without
the cost and complexity of buying and managing the underlying
hardware, software, provisioning and hosting.

  Infrastructure as a service (IaaS)

Infrastructure as a service provides companies with computing
resources including servers, networking, storage, and data
centre space on a pay-per-use basis.

   EXAMPLE

Most of us use cloud computing all day long without realizing it. When you sit at your PC and type a query into Google, the computer on your desk isn’t playing much part in finding the answers you need: it’s no more than a messenger. The words you type are swiftly shuttled over the Net to one of Google’s hundreds of thousands of clustered PCs, which dig out your results and send them promptly back to you. When you do a Google search, the real work in finding your answers might be done by a computer sitting in California, Dublin, Tokyo, or Beijing; you don’t know—and most likely you don’t care!

Thank You 🙂
