Cloud Computing Notes for ”Front End and Back End Architecture” Complete Notes for Chapter 3 of Cloud Computing for B.Tech and Diploma Classes

Front End and Back End Architecture

Cloud Computing architecture comprises of many cloud components, which are loosely coupled. We can broadly divide the cloud architecture into two parts:

Front End

Back End


Each of the ends is connected through a network, usually Internet. The following diagram shows the graphical view of cloud computing architecture:

Cloud Computing Architecture

Front End

The 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, Example – Web Browser.


Back End

The 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.


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 middle ware, which help the connected devices to communicate with each other.
