Cloud Computing - delivering hosted services over the Internet. Cloud computing is getting IT services, such as email, customer relationship management or web conferencing, over the internet.Instead of buying hardware and software up front, you pay a monthly charge based on the number of users.In simple words,when you type a query into Google, the computer does nothing with regards to answer, it's just a messenger. The words you type are sent over the Net to one of Google's numerous clustered PCs, which find your results and send them promptly back to you. The real work in finding your answers might be done by a computer sitting in California, Dublin, Tokyo, or Beijing!!Preparing documents over the Net is a newer example of cloud computing. Simply log on to a web-based service such as Google Documents and you can create a document, spreadsheet or presentation. Instead of typing your words into a program like Microsoft Word or OpenOffice, running on your computer, you're using similar software running on a PC at one of Google's world-wide data centers. Like an email draft, the document you produce is stored remotely, on a Web server, so you can access it from any Internet-connected computer, anywhere in the world, any time you like!!. Using a Web-based service like this means you're "outsourcing" some of your computing needs to a company such as Google: they pay the cost of developing the software and keeping it up-to-date and they earn back the money to do this through advertising and other paid-for services.Cloud Computing - delivering hosted services over the Internet.
