The document discusses cloud computing, defining it as a model relying on shared resources accessed via the internet, detailing three main service models: SaaS, PaaS, and IaaS, and their respective benefits and limitations. It also outlines four deployment models: public, private, community, and hybrid clouds. The document concludes that cloud computing is a rapidly evolving technology with significant advantages for users and organizations, despite challenges such as security and internet dependency.

2.  Introduction.
 Services Models of Cloud.
 Deployment Models of Cloud.
 Service Providers of Cloud.
 Benefits of Cloud Computing
 Limitations of Cloud
 Conclusion.

3. What is Cloud Computing?
 Cloud Computing is typically is type of computing
that relies on sharing computing resources rather
than having local servers or personal devices to
handle applications.
 Cloud Computing means "a type of Internet-based
computing," where different services to
organization's computers and devices provided
through the Internet.

4. Mainly cloud provides 3 Services.
 SaaS (Software as a service)
 PaaS (Platform as a Service)
 IaaS (Infrastructure as a Service)

5. It is sometimes referred to as "on-demand software”
 An application is hosted as a service to customers.
 Instead of installing and maintaining software, you
simply access it via the Internet.
 Application like Office, Messaging , CAD are
hosted.
Why SaaS ?
 Costs less money.
 Customization is easy.
 Multitenant Architecture

6.  Problems with SaaS:
 Organization that has a very specific
computational need might not be able to find
the application available through SaaS.

7.  PaaS vendors offer a development environment to
application developers.
 PaaS provides all of the facilities required to support
the complete life cycle of building and delivering web
applications and services entirely from the Internet.
 Why PaaS?
 Efficiently manage the application lifecycle.
 Cut coding time.
 Develop for multiple platforms—including mobile—
more easily.

8.  Data security.
 Customer captivity.

9.  IaaS Provides virtualized computing resources
over the Internet.
 IaaS Provides Full control of the computing
resources through administrative access to
VMs.
 Services like Virtual Storage, Load balancers
 , CPU cycles , Database .
WHY IaaS ?
 Cost saving.
 Pay as your requirement.
 Space & energy efficient .
 Portable.

10.  There are 4 Deployment Models of cloud
 Public Cloud.
 Private Cloud.
 Community clouds.
 Hybrid cloud.

11.  Public clouds are made available to the
general public by a service provider who
hosts the cloud infrastructure.

12.  Private cloud is cloud infrastructure dedicated
to a particular organization. Private clouds
allow businesses to host applications in the
cloud privately.

13.  Hybrid Clouds are a composition of two or
more clouds (private, community or public)
that remain unique entities but are bound
together offering the advantages of multiple
deployment models.

14.  A community cloud is a is a multi-tenant
cloud service model that is shared among
several or organizations and that is governed,
managed and secured commonly by all the
participating organizations or a third party
managed service provider.

15.  TOP SaaS providers :-
 Salesforce.com
 Accelops.
 Cloud9.
 Oracle's on demand

16.  Top PaaS Providers
 Amazon Web Services
 AT&T.
 Google.
 Windows Azure

17.  TOP IaaS Vendors
 HP.
 Amazon.
 IBM.
 AT&T.

18.  Flexibility.
 Disaster recovery.
 Automatic software updates.
 Capital-expenditure Free.
 Increased collaboration.
 Work from anywhere.
 Quick Deployment.

19.  Internet is backbone of computing.
 Cannot work in low internet.
 Security is big issue.
 Lack of support.
 Downtime.

20.  Cloud Computing is fast emerging
technology.
 Still in Beta so requires more development.
 Cloud computing is future of IT industry.
 It Provides tremendous benefits to customers
of all sizes: simple users, developers,
enterprises and all types of organizations.

