Cloud computing architecture is combination of a front end platform, back end platform, a loud based delivery and network.

A cloud computing architecture consists of two parts - Front End and a Back End that connect to each other through a network, usually the Internet. The front end is the side the computer user or client, sees. The back end is the “cloud” section of the system.

Front End: The front end of the cloud computing system comprises of the client’s devices and some applications are needed for accessing the cloud computing system. All the cloud computing systems do not give the same interface to users.

Back End: Back end refers to some physical peripherals. In cloud computing, the back end is cloud itself which may encompass various computer machines, data storage systems and servers. Groups of these clouds make a whole cloud computing system.  

Theoretically, a cloud computing system can include practically any type of web application program such as video games to applications for data processing, software development and entertainment residing on its individual dedicated server for services. There are some set of rules, generally called as Protocols which are followed by this server and it uses a special type of software termed as Middleware that allow computers that are connected on networks to communicate with each other.
