CLOUD COMPUTING

2. After the presentation….
What is cloud computing ?
Models & types
Uses
Advantages
Disadvantages
Future
And many more…..

3. When it's smarter to rent than to
buy…

5. And the answer is……
 Cloud computing is a model for enabling
ubiquitous, convenient, on-demand network access
to a shared pool of configurable computing
resources that can be rapidly provisioned and
released with minimal management effort or service
provider interaction.

6. In simple words….
Cloud computing means that instead
of all the computer hardware and software
you're using sitting on your desktop, or
somewhere inside your company's network,
it's provided for you as a service by another
company and accessed over the Internet.
 use application without installing and
access to all file in any computer through
internet.

7.  Query in Google.
 Email – mail client to hotmail.
 Google documents preparation.
 Social networks
 Health care
 Back up service
 Banking and financing.

8. Service models…
 Infrastructure as a service (IaaS)
- Network architects
 Platform as a service (PaaS)
- Application developers
 Software as a service (SaaS)
- End users

9. Infrastructure as a service(IaaS)…
 also known as hardware as a service.
 is a computing power that you can rent for a limited
period of time.
 allows existing applications to be run on a cloud
suppliers hardware.
 e.g. Web hosting – pay a monthly or a per mb/gb fee
to a hosting company.

10. Platform as a service(PaaS)…
is a platform for developers to write and create their
own SaaS i.e. applications.
 which means rapid development at low cost.
 E.g.: Salesforce.com, Windows Azure, Google app
engine etc.

11. Software as a service(SaaS)…
Just run it for me!
 also known as On-demand Service.
 is an application that can be accessed from anywhere
on the world as long as you can have an computer
with an Internet Connection.
 We can access this cloud hosted application without
any additional hardware or software.
 E.g. : G-mail, Yahoo mail, Hotmail etc..,

12. Cloud architecture

13. Deployment models…
a. Public cloud
 Services are rendered over a network that is
open for public use.
 Computing infrastructure is hosted by cloud
vendor at the vendors premises.
 can be shared by various organizations.
 E.g. : Amazon, Google, Microsoft, Sales force

14. Models cntd….
b. Private cloud
 The computing infrastructure is dedicated to a
particular organization and not shared with
other organizations.
 more expensive and more secure when
compare to public cloud.
 E.g. : HP data center, IBM, Sun, Oracle, 3tera

15. models cntd…
c. Hybrid cloud
Organizations may host critical applications on
private clouds.
 Where as relatively less security concerns on
public cloud.
 Usage of both public and private together is
called hybrid cloud.

16. models cntd…

17. Cloud storage…
All your files,
ready where you are
- Google drive-

18.  Several large Web companies are now exploiting the fact
that they have data storage capacity that can be hired out to
others.
 This is in contrast to local data storage, where data is
stored on the hard drive of a local desktop or a laptop.
 e.g. Amazon’s Elastic Compute Cloud (EC2) and Simple
Storage Solution (S3).

21. Advantages & disadvantages…
 pros
•Lower upfront costs and reduced
infrastructure costs.
•Easy to grow your applications.
•Instant software updates.
• Only pay for what you use.
• Overall environmental benefit (lower carbon
emissions) of many users efficiently sharing large
systems.

22. cons
•Higher ongoing operating costs.
• Greater dependency on service providers.
• What happens if your supplier suddenly decides
to stop supporting a product or system you've
come to depend on?
• Potential privacy and security risks of putting
valuable data on someone else's system in an
unknown location.
• Dependency on a reliable Internet connection.
• renting a fully furnished flat & purchasing one.
