2. CLOUD COMPUTING?
• “ 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. AN INTRODUCTION TO CLOUD
COMPUTING
• The cloud is a large group of interconnected
computers . It allows companies to offer
services to clients on a pay-by-use system. It
allows companies to store data on a virtual
server. It puts customer information and
applications in a virtual “cloud” that can be
accessed through the web. Customer can
enjoy software applications and information
storage at a low price.

4. 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. Thus it is a pc
centric New Model (Cloud Computing):
Provides all the infrastructure needed to run
applications over the Internet. That makes it
document centric.

5. WHY CLOUD COMPUTING
• Individual users connect to the cloud from
their own personal computers or portable
devices, over the Internet. To these individual
users, the cloud is seen as a single
application, device, or document. The
hardware in the cloud (and the operating
system that manages the hardware
connections) is invisible.

6. Understanding Cloud Architecture:
• It all starts with the front-end interface seen by
individual users. This is how users select a task or
service (either starting an application or opening
a document). The user’s request then gets passed
to the system management , which finds the
correct resources and then calls the system’s
appropriate provisioning services. These services
carve out the necessary resources in the
cloud, launch the appropriate web
application, and either creates or opens the
requested document.

7. Key properties of cloud computing
• User-Centric:
• Once as a user are connected to the
cloud, whatever is stored there- documents
, messages, images , applications whateverbecomes authorized to the user access them.
In addition, not only is the data, but one can
also share it with others. In effect, any device
that accesses your data in the cloud also
becomes yours.

8. Task-Centric
• Instead of focusing on the application and
what it can do, the focus is on what one need
done and how the application can do it for us.
Traditional applications— word processing
, spreadsheets , email and so on—are
becoming less important than the documents
they create.

9. Powerful
• Connecting hundreds or thousands of
computers together in a cloud creates a
wealth of computing power impossible with a
single desktop PC

10. Accessible:
• Because data is stored in the cloud, users can
instantly retrieve more information from
multiple repositories. We are not limited to a
single source of data, as we do with a desktop
pc.

11. INTELLIGENT
• With all the various data stored on the
computers in a cloud, data mining and analysis
are necessary to access that information in an
intelligent manner

12. Programmable
• Many of the tasks necessary with cloud
computing must be automated . For example
, to protect the integrity of the
data, information stored on a single computer
must be replicated on others computers in the
cloud. If that one computer goes offline, the
cloud’s programming automatically
redistributes that computer’s data to a new
computer in the cloud.

13. The leader in cloud computing.
• GOOGLE: Google offers several services
including e-mail and document creating
applications.
• Google claims its services are 99.99% reliable.
• Though users have experienced downtime.
• Bugs and glitches always occur with new
technology

14. AMAZON
• Amazon offers companies data storage services.
Companies only have to pay for the storage they use
• More and more companies are starting to trust cloud
computing services and turn begin to store their data
in the clouds.
• It appeals to companies because it eliminates time
employees spend on maintaining this data and
eliminates maintenance.

15. APPLICATION ON CLOUDING
COMPUTING
• PRACTICALLY LIMITLESS AND EASILY
ACCESSIBLE.
• IT SAVES THE COST OF INFRASTRUCTURE AND
HARDWARE MAINTAINANCE.
• IT PROVIDES THE ACCESS TO COMMERCIALY
AVAILABLE APPLICATIONS.

16. BENEFITS OF CLOUDING COMPUTING
•
•
•
•
•
•
REDUCED COST.
INCREASED STORAGE.
FLEXIBILITY.
HIGHLY AUTOMATED.
MORE MOBILITY.
ALLOWS IT TO SHIFT FOCUS.

17. RISK OF CLOUDING COMPUTING
•
•
•
•
COMPLIANCE.
DATA MOBILITY.
PRIVACY.
SERVICE LEVELS.

18. Conclusion
• Companies have to pick and choose and be
careful with what data they allow to be out
there in a cloud. This service will provide new
inventive ways to use computers and provide
services.
