Cloud Computing - Architecture

T he Cloud Computing architecture comprises of many cloud components, each of them are loosely coupled. We can broadly divide the cloud architecture into two parts:
  • Front End
  • Back End
Each of the ends are connected through a network, usually via Internet. The following diagram shows the graphical view of cloud computing architecture:


Front End refers to the client part of cloud computing system. It consists of interfaces and applications that are required to access the cloud computing platforms, e.g., Web Browser.


Back End refers to the cloud itself. It consists of all the resources required to provide cloud computing services. It comprises of huge data storage, virtual machines, security mechanism, services, deployment models, servers, etc.

Important Points
  • It is the responsibility of the back end to provide built-in security mechanism, traffic control and protocols.
  • The server employs certain protocols, known as middleware, helps the connected devices to communicate with each other.
