Computing Evolution

Now40’s 70’s 80’s

•Mobility explosion

•Collaboration

•High level of interconexion between users

•Web platform growing

•Pressure over companies data centre.

• The cloud is a large group of interconnected computers.

• It is a document-centric concept not PC centric.

In Business View:When it’s smarter to rent than to buy…..

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……

The Traditional Model :

• Building and running applications complex, expensive, and risky.

• Electricity needed to power the servers as well as the systems to keep them cool.

New Model (Cloud Computing):

• Provides all the infrastructure needed to run applications over the Internet.

• Can logically divides into 2 sections - Front End - Back End

How does Cloud Computing work?

Back End includes: - computer networks, servers, and any data storage

systems - practically, any computer program you can

imagine from data processing to video games. - Control node is also called as Central Server

•Cloud computing is still struggling in its infancy with negative and positive Comments.

•Academia is bit slower to react.

•Its security deficiencies and benefits need to be carefully weighed before making a decision to implement it..
