I love this video explaining cloud computing; it uses a picture of a dog. So many people are confused and who can blame them with all the hype out there. Some companies say that everything on the Internet is cloud computing. At it’s basic level, cloud computing is any computing capability offered on-demand over the Internet. It can be a photo-sharing site or your AP system. Rather than building it yourself, you only pay for what you use. So using cloud computing is like paying for your electricity.
You use it, you pay. You don’t, you don’t pay.
