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 internet. (Ex.. AWS, Windows Azure , etc)

Types of cloud model

PublicPrivateHybrid

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.

ConclusionCloud 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.
