Slide 9: What is cloud computing?
In View:
Business
When it’s smarter to rent than to buy…..
Slide 11: What is cloud computing?
Techie’s View:
It offers the ability to access softwares or information that can be delivered on-demand, over the internet, without the need to store it locally……
Slide 12: An Introduction to Cloud Computing
The cloud is a large group of interconnected computers.

Slide 13: Why cloud computing?
Building and running applications complex, expensive, and risky.
•
The Traditional Model :
New Model (Cloud Computing):
•
Electricity needed to power the servers as well as the systems to keep them cool.
•
Provides all the infrastructure needed to run applications over the Internet.
Slide 14: Scalability

Slide 22: How Cloud Computing Works?
Can logically divides into 2 sections - Front End - Back End
Slide 23: Front End includes:
- the client computer - application required to access the cloud computing(Mediator) Back End includes: - computer networks, servers, and any data storage systems - practically, any computer program you can imagine from data processing to video games.
