ABSTRACTION

- Use something without knowing what is going on inside.- Users are shielded from the details how something actually works.

An example of abstraction…

Key Steering wheel Gearshift Gas pedal Brakes

We seldom worry about the thousands of highly specialized parts that are combined to produce the car…!

Cloud !!

A Cloud depicts the Internet in computer network as an abstraction of the underlying infrastructure it represents.

Internet

hardware, software and internetworking infrastructure

INTERNETprovides

hardware,software and networking services to End Clients

A collection or groups of integrated and networked

THIRD-PARTY PROVIDER

Customers

• Cloud computing customers do not own the physical infrastructure.• They consume resources as a service.• The service is fully managed by the provider.• The consumer only needs a personal computer and Internet access.

Three layers to cloud computing…

application

platform

infrastructure

Companies use these layers differently based on what they offer.

You pay for them when you are using them, andYou pay for them when your not using them…

And the more you pay on their maintenance…

INSTANT !!

HOW DOES IT WORK ???

•No need of running heavy servers and maintaining them.

•Instead, run applications on a shared data centers.

•Just plug in to the shared data servers just like using a utility.

•Its fast to get started and costs less.

When using any application in the cloud, the client just needs to log in to his account; just like any other application and access his resources!!

CLOUD COMPUTING

Types of Clouds

•Public• Resources are dynamically provisioned on a self-service basis.• Provided by an off-site third-party provider who shares resources and

bills utility computing basis.•Private

• Capitalise on data security, corporate governance, and reliability concerns.

• Users "still have to buy, build, and manage clouds“• lacks the economic model that makes cloud computing such an

intriguing concept. •Hybrid

• A hybrid cloud environment consists of multiple internal and/or external providers.

CHALLENGES OF CLOUD COMPUTING

CONTROL OF OUR DATA IS TRANSFERRED TO THIRD PARTYBUSINESS FAILS IF SUPAILSPLIER GOES BANKRUPTCOMPETITOR CAN KNOW OUR BUSINESS EASILY AS DATA IS IN CLOUD

FINDINGS

Cloud Computing is a paradigm in which information is permanently stored in servers on the Internet.The future for cloud computing is bright. The big names in computers are throwing lots of resources into this.

FINDINGS

Platforms provide an on demand, always on, anywhere, anytime and any place, pay as used and as needed.The whole idea behind it is resizable computing power. When you need the power, it's there, but when you don't, you can scale back.

FINDINGS

CLOUD COMPUTING CAN BE USED AS MOBILE TREND IF INTERNET FACILITY BECOMES EASY

LATEST UPDATE

MICROSOFT MADE A CLOUD BASED OS…8TH MARCH 2010

CONCLUSION

HAS GOOD HARDWARE MANAGEMENTSECURITY IS ADVANTAGE AS WELL AS THREATMADE BUSINESS LIFE EASYHOWEVER NOT AVAILABLE TO ALL

CONCLUSION

USE OF IT DEPEND ON THE TYPE OF BUSINESS IS DONEFLEXIBLE IN TERMS OF DATA AVAILABILITY AND RESOURCE USABILITYHUGE DATA AVAILABILITY BUT MAINTENANCE IS A CHALLENGE

CONCLUSION

There are a lot of criticisms about the security in cloud computing.Some have said stored information in the cloud is safer than on premise, but others disagree.
