There are good chances you already came across the term “cloud computing” once or twice, even if you don’t completely grasp the meaning of the term. If that is the case, check out this article on Business Week titled How Cloud Computing Is Changing the World. It gives some good examples of how cloud computing is starting to shape the way companies do business, and individuals interact with IT. Here is a small quote:
The term “cloud computing” encompasses many areas of tech, including software as a service, a software distribution method pioneered by Salesforce.com about a decade ago. It also includes newer avenues such as hardware as a service, a way to order storage and server capacity on demand from Amazon and others. What all these cloud computing services have in common, though, is that they’re all delivered over the Internet, on demand, from massive data centers.
A pit-stop on the Wikipedia article for cloud computing can help also. This is probably one of the most important shifts that we will see on the coming years, so make sure to understand it.
