ABSTRACT

CLOUD COMPUTING

Cloud computing is Internet-based computing, whereby shared resources, software and

information are provided to computers and other devices on-demand, like a public utility. A

technical definition is "a computing capability that provides an abstraction between the

computing resource and its underlying technical architecture.

It is aparadigm shift following the shift from mainframe to client-serverthat preceded it in

the early '80s. Details are abstracted from the users who no longer have need of, expertise in, or

control over the technology infrastructure. (e.g., servers, storage, networks). Traditional businessapplications have always been very complicated and expensive. The amount and variety of

hardware and software required to run them are daunting. You need a whole team of experts to

install, configure, test, run, secure, and update them.

With cloud computing, you eliminate those headaches because youre not managing

hardware and software thats the responsibility of an experienced vendor like salesforce.com.

The shared infrastructure means it works like a utility: You only pay for what you need,

upgrades are automatic, and scaling up or down is easy. Cloud-based apps can be up and running

in days or weeks, and they cost less. With a cloud app, you just open a browser, log in, customize

the app, and start using it.

The latest innovations in cloud computing are making our business applications even more

mobile and collaborative, similar to popular consumer apps like Facebook and Twitter. As

consumers, we now expect that the information we care about will be pushed to us in real time,

and business applications in the cloud are heading in that direction as well. With Cloud 2,

keeping up with your work is as easy as keeping up with your personal life on Facebook.
