CLOUD COMPUTING?

•  “ Cloud” is actually a metaphor for the Internet. Cloud computing is a paradigm in which information is permanently stored in servers on the Internet.

AN INTRODUCTION TO CLOUD COMPUTING

• The cloud is a large group of interconnected computers . It allows companies to offer services to clients on a pay-by-use system. It allows companies to store data on a virtual server. It puts customer information and applications in a virtual “cloud” that can be accessed through the web. Customer can enjoy software applications and information storage at a low price.

THE TRADITIONAL MODEL

• Building and running applications complex, expensive and risky. Electricity needed to power the servers as well as the systems to keep them cool. Thus it is a pc centric New Model (Cloud Computing): Provides all the infrastructure needed to run applications over the Internet. That makes it document centric.

WHY CLOUD COMPUTING

•  Individual users connect to the cloud from their own personal computers or portable devices, over the Internet. To these individual users, the cloud is seen as a single application, device, or document. The hardware in the cloud (and the operating system that manages the hardware connections) is invisible.

Understanding Cloud Architecture:

•  It all starts with the front-end interface seen by individual users. This is how users select a task or service (either starting an application or opening a document). The user’s request then gets passed to the system management , which finds the correct resources and then calls the system’s appropriate provisioning services. These services carve out the necessary resources in the cloud, launch the appropriate web application, and either creates or opens the requested document.

 Key properties of cloud computing

• User-Centric:• Once as a user are connected to the cloud,

whatever is stored there- documents , messages, images , applications whatever-becomes authorized to the user access them. In addition, not only is the data, but one can also share it with others. In effect, any device that accesses your data in the cloud also becomes yours.

Task-Centric

• Instead of focusing on the application and what it can do, the focus is on what one need done and how the application can do it for us. Traditional applications— word processing , spreadsheets , email and so on—are becoming less important than the documents they create.

Powerful

• Connecting hundreds or thousands of computers together in a cloud creates a wealth of computing power impossible with a single desktop PC

Accessible:

•   Because data is stored in the cloud, users can instantly retrieve more information from multiple repositories. We are not limited to a single source of data, as we do with a desktop pc.

INTELLIGENT

• With all the various data stored on the computers in a cloud, data mining and analysis are necessary to access that information in an intelligent manner

Programmable

• Many of the tasks necessary with cloud computing must be automated . For example , to protect the integrity of the data, information stored on a single computer must be replicated on others computers in the cloud. If that one computer goes offline, the cloud’s programming automatically redistributes that computer’s data to a new computer in the cloud.

 The leader in cloud computing.

• GOOGLE: Google offers several services including e-mail and document creating applications.

• Google claims its services are 99.99% reliable.• Though users have experienced downtime.• Bugs and glitches always occur with new

technology

AMAZON

• Amazon offers companies data storage services. Companies only have to pay for the storage they use

• More and more companies are starting to trust cloud computing services and turn begin to store their data in the clouds.

• It appeals to companies because it eliminates time employees spend on maintaining this data and eliminates maintenance.

APPLICATION ON CLOUDING COMPUTING

•  PRACTICALLY LIMITLESS AND EASILY ACCESSIBLE.

• IT SAVES THE COST OF INFRASTRUCTURE AND HARDWARE MAINTAINANCE.

• IT PROVIDES THE ACCESS TO COMMERCIALY AVAILABLE APPLICATIONS.

BENEFITS OF CLOUDING COMPUTING

• REDUCED COST.• INCREASED STORAGE.• FLEXIBILITY.• HIGHLY AUTOMATED.• MORE MOBILITY.• ALLOWS IT TO SHIFT FOCUS.

RISK OF CLOUDING COMPUTING

• COMPLIANCE.• DATA MOBILITY.• PRIVACY. • SERVICE LEVELS.

Conclusion

• Companies have to pick and choose and be careful with what data they allow to be out there in a cloud. This service will provide new inventive ways to use computers and provide services.
