CLOUD COMPUTING: The Next Big Thing

Cloud computing or computing in the cloud is now one of the latest happening trends in the business world and the “next big thing” after Web 2.0. According to a 2008 paper published by IEEE Internet Computing “Cloud Computing is a paradigm in which information is permanently stored in servers on the Internet and cached temporarily on clients that include desktops, entertainment centers, table computers, notebooks, wall computers, handhelds, sensors, monitors, etc.” In other words, we can say that this is about increasing an organization’s or user’s capability by using different applications from some external servers without investing much on its own infrastructure and maintenance of local servers. Rather the organization/user pays for raw computing power. Here the word “cloud” is used as a metaphor for internet.

The basic architecture of this cloud computing is a massive network of interconnected servers where the web applications reside. The user accessing these applications need not be aware of the physical location of the application’s computer. This not only reduces the cost of installing licensed software at the end user’s computer but also saves the cost associated with deploying, maintaining and upgrading of different business technologies.
