Experts have said the future of the internet belongs to the cloud

Cloud computing is the 4th quarter of 2007, the emergence of a term. The definition and connotation of it are different, we can find at least 100 kinds of statements on the Internet, but there is no accepted definition. This paper tries to synthesize the advantages of each family, and proposes the definition and characteristics of cloud computing. The requirement for this definition is to capture the nature of cloud computing in the most refined language, to cover today's popular typical cloud computing solutions (including Google Cloud computing, Amazon Cloud computing, Salesforce cloud computing, cloud security, etc.), but to differentiate other relevant concepts such as Grid computing, Parallel computation, etc.).

Definition: Cloud computing (Cloud Computing) is a new business computing model. It distributes computing tasks on a large pool of computer-made resources, enabling various application systems to acquire computational power, storage space and various software services as needed.

This resource pool is called the cloud. The cloud is a virtual computing resource that can be maintained and managed, typically for some large server clusters, including compute servers, storage servers, broadband resources, and so on. Cloud computing centralizes all computing resources and is automatically managed by software without human involvement. This allows application providers to be more focused on their business, in favor of innovation and lower costs, without having to worry about tedious details.

One analogy: It's like switching from an old single generator to a centralized power supply model. It means that computing power can also be used as a commodity circulation, like gas, water and electricity, easy to use, low-cost. The biggest difference is that it is transmitted over the Internet.

Cloud computing is the development of parallel Computing (Parallel Computing), distributed Computing (distributed Computing) and Grid computing (grid Computing), or the business implementation of these computer science concepts. Cloud computing is the result of a hybrid evolution of virtualization (Virtualization), Utility Computing (Utility Computing), IaaS (infrastructure as a service), PaaS (Platform-as-service), SaaS (software, services), and so on.

Cloud computing is now widely discussed as the Internet hotspot, many internet giants have announced that they will come up with their own cloud products, experts have also said that the future of the internet belongs to the cloud. With China's strategic emphasis on cutting-edge science and hot subjects, China Electronic Society cloud computing Expert Committee was born.

At the founding meeting of the Cloud Computing Expert Committee, Mr. Li Deii, Vice chairman of China Academy of Engineering, IBM Greater China Chief Technology President Ye Tianjong, director of the Department of Higher Education, Zhang, Mr. Huang, director of China Mobile Research Institute, has published his views on cloud computing.

The following are the main points of the press

Li Deii Academician: Convergence and integration is the future

As the chairman of the cloud Computing conference, academician Li DEII that China is not lack of academic criticism, the lack of academic commentary, communication too little lead to the collision and convergence of wisdom. Cloud computing is the integration of the resources of the entire Internet, but we should not regard it as a gimmick, but should see what the cloud means.

Academician Li said that the Internet has 500 million IP addresses, 1.17 billion users, 109 million clear web sites, 29.7 billion web pages, and an average of 5 pages per person, and that in 06, 16.1 billion of the world's information was created as a boon, more than the sum of information over the past thousands of years.

This makes any personal computer seem insignificant compared to the resources of the entire Internet. On the Internet, the calculation and distribution of resources are also put on the agenda. This is the background of cloud computing coming.

Li Deii that the best aspect of cloud computing is flexibility, personalization, multiple, simple applications and services. And for the speculation cold sell, the concept of hot, market cold situation, said Lee, this is just everyone still hesitate, we can not tell whether cloud computing is the concept of speculation or the future trend.

And if you can't tell the story, you can look at history. It is historically rare for all large companies to announce a march into the same concept and project. From the point of view of software engineering, academician Li believes that the future software design needs to be based on the network node, based on the cloud computing fusion to develop. The sharing, circulation and change of information resources need us to study and discuss. "The essence of life is in the form of matter, not in the matter itself," Langton, a member of the Li, quoted Chris as saying. The same is true for information resources.

After briefly introducing the rise of cloud computing, Li Deii that cloud computing should have four features. The first feature is virtualization, the second is multiple granularity and multi-scale--the flexibility to face demand. The third is uncertainty, which was previously said to be fuzzy calculation and so on. The fourth feature is soft computing, saying how to let the network understand some quantitative, qualitative conversion-such as some approximate quantifiers.

In addition, academician Li also talked about three representations of cloud computing model, and discussed the cloud computing model can effectively solve the complex problems of Internet cloud evolution, cloud control, cloud inference and soft computing.
