So imagine you have a dog and your dog’s
name is Frank it’s a strange dog name, but just go with
it.You and Frank are best pals. You are going walks together, Frank always walks faster, but still you really love Frank, a lot.You only have one photo of Frank though. This goofy shot, of Frank at his birthday party drooling on a cake. And because you love this weirdly named dog so much you are worried you might lose this photo, so you upload the photo, your favorite photo in one of your favorite photo websites like flickr, facebook, or picasa. And without even realizing it, you just started cloud computing. But what does that mean? When you put Franks photo online, you can picture a giant cloud coming down to vacuum up this photo off your laptop, then the photo of Frank lives up in the cloud until you need to look at it again. You log into Flickr or facebook, and theres frank. You can see him from whenever you want, from home, from work, even on your phone in case you start missing Frank during lunch break At first the cloud seems like magic,but its not. The photo of Frank isnt flying around in the sky. Franks photo actually lives in a secret warehouse, full of computers. These warehouses are called data servers or server farms and they are popping up all over the world just like crops. inside one of the computer warehouses there are rows and rows of refrigerator sized computer towers that are way more powerful than your
home computer. It’s hard to know exactly where your photo of Frank may be once its in the cloud Thats because it might be in a dozen of these warehouses, all at once. Frank may be chilling in Paris or
hanging out in India there is really no way to know for sure. You’d just have to trust the web company like google or microsoft . to keep Frank safe There are a bunch or reasons to do this. The first is that well you only have one photo of Frank. Its on your laptop and if that laptop breaks if an alien
comes to steal the data or your apartment melts when a volcano erupts, you are out of luck. no more Frank, no more memories. But when Frank is in the cloud, he’s stored in not just one place, but all over the place so you are less likely to lose him. You can also access Franks photo from anywhere. you can send the link to some other friend, so they can see Frank too. Thats just one of the many powers of cloud computing, and its not just you and Frank, entire businesses are running in the
cloud and there are plenty of reasons to be scared of the cloud too, but for now you decide to trust the cloud, as backup. If Franks happy, then you are happy.
