1. What is Cloud Computing?

Cloud computing is an information technology paradigm that enables ubiquitous access to shared pools of configurable system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet.
Cloud Computing provides us a means by which we can access the applications as utilities, over the internet. It allows us to create, configure, and customize the business applications online. This tutorial will take you through a step-by-step approach while learning Cloud Computing concepts.

2. How Does Cloud Computing Work?

Cloud computing provides a simple way to access servers, storage, databases and a broad set of application services over the Internet. A Cloud services platform such as Amazon Web Services owns and maintains the network-connected hardware required for these application services, while you provision and use what you need via a web application.

3. Cloud Computing Technologies?

There are certain technologies that are working behind the cloud computing platforms making cloud computing flexible, reliable, usable. These technologies are listed below:

Virtualization

Service-Oriented Architecture (SOA)

Grid Computing

Utility Computing

3. Cloud Computing Architecture?
The Cloud Computing architecture comprises of many cloud components, each of them are loosely coupled. we can broadly divide the cloud architecture into two parts:

a. Front End
Front End refers to the client part of cloud computing system. It consist of interfaces and applications that are required to access the cloud computing platforms. Eg. Web Browser

b. Back End
Back End refers to the cloud itself. It consist 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.
