WHAT IS CLOUD COMPUTING ? An emerging computer paradigm where data and services reside inmassively scalable data centers in the cloud and can be accessed from

any connected devices over the internet

ITS ARCHITECTURE

FRONT END

It can be end user or client or any application (i.e. web browser etc.)

which is using cloud services.

It is the side at which the user of the computer or the client himself is

able to access. This involves the clients network or his computer and

the program or programs that he uses to access the database or the

servers that contain all the data

BACK END

It is the network of servers with any computer program and data storagesystem.

It is the cloud itself, which is the collection of all related information

saved in the servers that the client wishes to have access to.


8/21

These two ends of cloud computing architecture are connected through

a network, usually the Internet, toprovide remote access to all the users

of the cloud.

CLOUD COMPUTING INFRASTRUCTURE

MODELS


10/21

PUBLIC CLOUD

A service provider makes resources, such as applications andstorage, available to the general public over the Internet.

Public cloud services may be free or offered on a pay-per-usagemodel.

Examples of public clouds include Amazon Elastic Compute Cloud(EC2), IBM's Blue Cloud, Sun Cloud, Google App Engine and

Windows Azure Services Platform.


11/21

PRIVATE CLOUD

Computing architecture is dedicated to the customer and is not

shared with other organisations.

Private clouds are built for the exclusive use of one client, providing

the utmost control over data, security, and quality of service

They are expensive and are considered more secure than Public

Clouds.

Private clouds operate inside the firewall and are built upon

virtualization software such as VMware or Xen


12/21

HYBRID CLOUD

Hybrid clouds combine both public and private cloud models

Like the private model, a hybrid cloud lets an organization continue

to use their existing data center equipment and keep sensitive datasecured on the organization's own network.

like the public cloud, a hybrid model lets an organization takeadvantage of a cloud's almost unlimited scalability. It's a way tosolve some of the trust issues of the public cloud while getting the

public cloud's benefits.


13/21

COMMUNITYCLOUD

The cloud infrastructure is shared between the organizations of the

same community.

Like, all the government agencies in a city can share the same cloud

but not the non government agencies.

Examples of community cloud include Googles Gov Cloud.

ISSUES IN CLOUD COMPUTING

PRIVACY Because of using common platform, and shared data, some security

and user identification software has to be used.

Service provider has to make users data secure.

AVAILABILITY& PERFORMANCE

Your all data is online.

If you can not reach your data, you can not work .

Your service provider has to be accessible all time


19/21

UNAUTHORISED ACCESS

Data's must be accessible to right people

Rules regarding access to data.

Encryption.

PHUSICAL RISKS

Data can be physically destroyedby natural disasters.

Proper backup must be taken.

PHYSICAL SECURITY Service provider has to be aware of their worker

Data leakage must be prevent.


20/21

CONCLUSION

Its is a powerful new abstraction for large scale data processing systems

which is scalable, reliable, cut costs and available.

Have large self-managed server.

Its particularly valuable to small and medium businesses to obtain more

productivity without spending lots of money on in-house resources andtechnical equipment.

Every model of cloud computing allows organizations to use -- and payfor services which employees actually need.

With the right middleware, a cloud computing system could execute allthe programs a normal computer could run from generic word

processing software to customized computer programs designed for aspecific company .
