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????

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.

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

Types of cloud model
 Public
 Private
 Hybrid

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.

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.

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

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.

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.

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.

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.
