This document summarizes a colloquium presentation on cloud computing given by Vivek Kumar. It defines cloud computing as delivering computing services over the internet, including servers, storage, databases, and software. It describes the main types of cloud models as public, private, and hybrid clouds. It outlines the advantages of cloud computing such as scalability, flexibility, and reduced costs compared to maintaining physical infrastructure. It also notes some disadvantages like dependence on internet access and potential additional storage costs.

3. Introduction to Cloud Computing
Storage devices
Flash Drive(or Pen drive)
Hard disk
Memory Card, CDs, DVDs, etc.
Reasons to Data loss
Damaging of device.
Data or software corrupt.
Device or data stolen by someone.
SO WHAT THE SOLUTION????

5. What is cloud computing
? Cloud computing is the delivery of computing services –
servers , storage ,databases, networking , software and
more
over the internet.
 Provide self service on demands.

6. Classifications as service
 SaaS (software-as-a-service)
users can access various software applications on a pay-
per- use basis.(Ex..Google app , g-
mail,etc)
PaaS (platform-as-a-service)
provides a platform allowing customers to develop, run,
and manage applications without complexity .
(Ex..Google app engine , force.com, etc)
IaaS (infrastructure-as-a-service)
provides virtualized computing resources over the

7. Types of cloud model
 Public
 Private
 Hybrid

8. Public cloud
 A public cloud is one based on the
standard cloud
computing model , in which a service provider
makes
resources, such as applications and storage,
available to
the general public over the Internet. Public cloud
services may be free or offered on a pay-per-usage
model.
 Ex- Amazon, Google AppEngine , etc.

9. Private Cloud
 Private cloud is a type of cloud computing that delivers
similar advantages to public cloud, including scalability
and self-service, but through a proprietary architecture.
Unlike public clouds, which deliver services to multiple
organizations, a private cloud is dedicated to a single
organization.
 Ex- g-mail, facebook ,etc.

10. Hybrid Cloud
 Hybrid cloud is a mix of private cloud and
public cloud computing.
 Hybrid cloud gives flexibility .
 Used in businesses.

11. Cloud Storage
 Cloud storage is a service model in which data is
maintained,
managed, backed up and made available to user over a
network .
 Different from external storages devices.
 Stored data can access any where via internet.

13. Advantages
 Cloud computing do not need high quality equipment
for user, and it is very easy to use.
 Cloud is a large resource pool that you can buy on-
demand service.
 Reduce run time and response time.
 Provides secure data storage center.
 Storage availability and data protection.
 Back up & recovery data.

14. Disadvantages
 Data can not be access without internet.
 Having sufficient storage ,may have additional
charge.
 If you want to be able to manipulate your files
locally through multiple devices, you’ll need to
download the service on all devices.
 Slow transferring data.

15. Conclusion
 Cloud computing is changing the way IT
departments buy IT. Businesses have a
range of paths to the cloud, including
infrastructure, platforms and applications
that are available from cloud providers as
online services.
 Online access data and storage in any
where.
