The cloud is simply a server that is somewhere in the world. The purpose is to give folks a place to store stuff so they can access it anywhere (but you have to have internet connections) and so they don't need a big hard drive. DH had a bad experience -- he was storing pictures on a web site (what we used to call the cloud) and the site closed down and we could not get out pictures. I prefer to keep everything locally --you can get a big thumb drive that works well for storing pictures (I do it all the time).
