What is Cloud Computing ?

Cloud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flowcharts and diagrams.

So what’s a definition for real people?
Cloud Computing = Web Applications


That’s all there is to it. If you’re using a web or internet-based application from a major provider like Google or Microsoft, you’re using cloud computing. Congrats!


Every web application that you’ve ever used, like Gmail, Google Calendar, Hotmail, SalesForce, Dropbox, and Google Docs, are based on “cloud computing”, because when you connect to one of these services, you’re really connecting to a massive pool of servers somewhere out there on the internet. The client doesn’t need to be a web browser, but that’s the direction everything is heading.
