THE OVERVIEW OF CLOUD COMPUTING

Wikipedia thinks cloud computing is a computing model can dynamically scalable virtualized resources through the Internet service available to the users.

The "Cloud Computing White Paper(Summary)", pointed out that cloud computing is an Internet-based, public participate computing model, the computing resources are dynamic, scalable,virtualization, and available by services.

The development of cloud computing

The Architecture of cloud computing

The typical cloud computing mainly consists of three service models, respectively, IaaS, PaaS, SaaS, known as the three-tier architecture of cloud computing.

the Architecture of cloud computing

IaaS delivers to users the fundamental basis ofimplementation of the resources. The layer provides the virtualized computing resources, storage resources and network resources.

PaaS is for software developers, they can use these public resources to develop customized applications.

PaaS with the easy used interfaces, compatibility and scalability.

SaaS delivers to users' customized software. User nolonger need to locally installed software, the software is delivered by services; users only need to pay-as-demand.

THE CURRENT DEVELOPMENT OF CLOUD COMPUTING

The New York Times using Amazon EC2 service complete the originally planned 11 million articles and images change into PDF documents‘ work using less than $300 within 24 hours.

Cloud computing can help people realize the goal of reduce cost and improve efficiency.

The overseas current development of cloud computing

Currently, the Amazon,Google, Microsoft and other companies have their own cloud computing infrastructures and cloud platforms.1. Amazon AWS

2. Google Engine

3. Microsoft Azure

THE APPLICATION ANALYSIS OF CLOUD COMPUTING INTHE TELEVISION AND BROADCASTING FIELD

New competition patterns, commercial modes and technical support systems have been introduced into the television and broadcasting industry.

Cloud computing has broad application prospects in the television production and broadcasting, new media applications, the tri-networks integration and the nextgeneration of broadcasting television network(NGB).

The application of cloud computing in television program production

• At present, almost all the program productions have commonly used the HD format.

• A good management and make full use of the broadcasted program data again brings great social benefits and economic values.

• Each local TV stations now have already established the management system of the program files.

• But these systems are scattered layout,services single, not formed the centralization, large scale management and service pattern, and can't meet all types of end users' program needs.

• Cloud computing can through the transformation of the content resource management systems, constrnction the regional TV program content resource system,and gradually form more pieces of independent TV program content resources cloud media, the cloud media finally can interconnected with each other.

• Using cloud computing transform the process of TV program production can greatly improve the work efficiency, reduce the production cost, and build the core competitive power.

The application of cloud computing in new media

• Network TV can help the traditional media and new media integration.

• Network TV needs the client-port mode.• That mode will move more computing power from

the terminal to the net, as users increased the video business broadband also increased, the power of protocol conversion,format conversion and content storage capacity demand will increase sharply, and a way to solve it is using the cloud computing platform.

conclusion

Cloud computing will change the television and broadcasting industry business process.

cloud computing will provide the continuous development of television and broadcasting field to make new contributions.
