Cloud computing is a simple technology that has been around for a while, and almost all of us have used it, without even knowing. In simple terms, cloud computing entails running computer/network applications that are on other people’s servers using a simple user interface or application format. In the olden days of networking, way before Google or Yahoo was born, companies ran e-mail as an application whose data was stored in-house. As such, all the files, documents, messages, and other things you currently use in e-mail were stored in a safe, dark room on the company’s premises. These sounds familiar because you were probably banned from visiting that room due to security reasons.

20th century, when companies like Google started showing up, the way e-mail was treated and utilized was revolutionized. It would have been a commercial bid to get more subscribers, but these companies chose to open their servers to store e-mail information for you, free of charge. However, to access that data, you have to use their applications like Gmail, Yahoo Mail, and so many others. Practically, this is what cloud computing is all about – using other people’s servers to run applications for your organization, remotely.
