1. CHANGING THE WAY IT WORKS

2. • “Cloud” is actually a metaphor for
the Internet.
• Cloud computing is a paradigm in
which information is permanently
stored in servers on the Internet.

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

4. 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……

5. • The cloud is a large group of
interconnected computers.
• It is a document-centric
concept not PC centric.

6. 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.

8. IaaS- Infrastructure as a Service
• The IaaS layer extends the virtualization layer
by providing the mechanisms to provision and
control the virtual machines in a utility computing
manner.
• The end user is able to control cost by knowing
exactly how much each virtual machine instance
costs per minute/hour.

9. PaaS- Platform as a Service
• Seeks to minimize the hassle and complexity
in deploying an application in the cloud.
• A programming platform is presented to the
end user, typically a developer at this point,
which leverages and API and programming
language.

10. SaaS- Software as a Service
• Simple way to get the application functionality
you need without incurring the cost of developing
that application.
• In this layer, even the platform has been
abstracted away from you as and end user.

11. PRACTICALLY LIMITLESS AND
EASILY ACCESSIBLE
IT SAVES THE COST OF
INFRASTRUCTURE AND HARDWARE

15. •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..
