What is cloud computing?

Actually you have been using cloud computing all the time, Dropbox and Google for exmple are cloud computing providers. So what does it mean? In simple terms cloud computing is the ability to use the power of other computers (located somewhere else) and their software via the internet. You do not need to own them, they are provided to you as a service. By utilising the cloud everything is ready for you, all the time, and you as a user don’t have to think about how it works. It is just there in the vast “cloud” that represents the internet.
