What is Cloud Computing?

Please tell it fullyWhat is Cloud Computing?
Till now when we work, we generally store our resources in our comp's hard drive. Similarly companies store their resources in there server. Now this is a costly affair, mainly from companies point-of-view. As they need to continuously update %26amp; update their servers. Also, when the data is too huge one cannot store in one server, but multiple servers. This increases cost further. Also, when you buy a server it's a sink cost.



Now there are companies who are saying that they will store %26amp; allow companies data %26amp; resources from their own server. The company just have to pay for the use of resources. The way companies access the data in some other's server is through internet. This is the whole idea of cloud computing.



I work in software testing industry. We use cloud computing apps to test softwares. This reduces the cost %26amp; increase efficiency as we now getting the cutting edge technology at a very low cost. Please find the link below to know more about use of cloud computing is software testing industry. This is one industry which greatly benefited from the presence of cloud computing.

It essentially means that your PC is downgraded to a dumb terminal with only an Internet browser, and instead of doing things such as running a word processor locally and saving your document on your hard disk, or running your spreadsheet locally, or whatever, your computing applications are performed by one or more servers over the Internet, and your documents are saved out there also.



Netbooks are a step in that direction, with much less capability than other computing machines, he expectation being that you only need it to go online.



There are probably more exotic and sell-the-idea-related descriptions available, but that's pretty much it in a nutshell.What is Cloud Computing?
Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, as with the electricity grid.
