Cloud computing has been around for several years. It's called cloud computing because the data and applications exist on a "cloud" of Web servers that may be anywhere in the world.
Cloud Computing Architecture (How the Cloud is structured)
Think of the cloud as being divided into two sections: the front end and the back end. They connect to each other through a network, usually the Internet.
The front end is the side we as computer users, or clients, see. The front end includes the client's computer (or computer network) and the application required to access the cloud computing system. Those applications can be your browsers (Firefox, Chrome, Internet Explorer) or unique applications developed just to get to the cloud.
The back end is the "cloud" section of the system. It's made up of the various computers, servers and data storage systems needed to provide the "cloud" of computing services. In
theory, a cloud computing system could include practically any computer
program you can imagine, from data processing to video games. Usually,
each application will have its own dedicated server.
