How would you go about explaining cloud computing to someone at YouTube that doesn't have a technical background?

"The easiest way to understand the cloud is that it is just another computer, phone, or storage device which is located remotely. It is similar to your hard drive or USB drive, except you access it via the Internet instead of directly on your computer. The cloud can also host applications and execute them remotely. Again, this is similar to your computer, cell phone, or any other device you may use here at YouTube. Whenever you make a phone call, ask Google for information, or order something on Amazon, you are using the cloud."
