China's "cloud computing Industry" is on the eve of the explosion

The IT industry has never lacked a hot concept, from SOA, sass to the current cloud computing, has become a hot spot.

China's cloud computing industry has been heavily supported by the NDRC and is on the eve of a massive outbreak. According to the White Paper on the development of China's cloud computing industry, China's cloud computing market will reach 60.678 billion yuan by 2012.

Looking internationally, e-commerce giant Amazon has launched a 199-dollar tablet, and Oracle, which insists that "only all-inclusive software companies can survive", has bought a high-end server for the Sun computer System (China) Limited (Sun), announcing the launch of a public cloud service, "cloud computing" The time seems to be really coming.

In order to get a deeper and more detailed understanding of cloud computing, "China News" special correspondent on cloud computing application and background of cloud computing operators-century interconnection technology strategy, the chief expert Dr. Li Zhijian interviewed.

"' Cloud ' is definitely the need of the green age, with the rapid development of the Internet and the ICT industry's power consumption accounted for the total proportion of global electricity consumption, the green value of cloud computing will become more and more obvious." "Li Zhijian the technical background and value of the cloud computing industry," he said.

The technical background of cloud computing is that the hardware performance is increasing CPU computing resources are increasingly wasted, the current information system, whether the backend server or the front-end terminal CPU utilization of about 20%, resulting in saving the user's IT investment to avoid idle waste and "change" the calculation model needs.

"For users, the change to avoid idle waste is to ' reuse hardware and system software ' through virtualization," Li Zhijian said. Users can use the ' rent ' rather than ' buy ' way of hardware such as software and servers, which is a value for reducing the input of users ' information construction and improving the efficiency of computing resources. ”

For many ordinary Internet users, the simplest understanding of cloud computing is the storage space on the server, which allows users to use the computing power and data stored on the server over a network connection. But the problem also comes with, your own data stored in other people's space, security how to guarantee?

On this issue, Li Zhijian said: "Users of the ' cloud security ' concerns are mainly psychological barriers, in the physical sense, the server in their own rooms and placed in the data center of the room there is no difference, and even professional data center of the physical risk is lower, such as more powerful anti-theft. As for the issue of user rights, in fact, as long as the Internet access, application software from the Internet to make a patch can also lead to the entire system remote control. Cloud computing security does not go beyond the traditional sense of computer security, of course, the "public cloud" and "private network" the difference between the need for further research and demonstration. ”

"In fact, Amazon's users already include many of the world's top 500 companies, and have signed the U.S. government's low security level application." Domestic users can start from the Non-core business applications, or from the low security level of the information system, and then gradually put the information system ' moved ' to the ' cloud '. Of course, the relevant government departments should also introduce measures to assess and certify the ' cloud services ' security level. "Li Zhijian suggested.

With the development of cloud computing in China, major service providers, including terminals, applications, platform services, and network infrastructure services, have also started the industrial chain layout for the cloud computing market. Although cloud computing in our country's business model is still relatively vague, but the future of cloud computing is worth looking forward to.

Since users can "reuse" background hardware and software resources, then cloud computing future terminal trend has become a matter of concern.

"Terminals will become more and more ' thin ', which means that the operating system's kernel and browser will be the most important part of the 600M CPU can be used effectively." Of course, different types of terminal usage patterns have different positioning, but the ' cloud ' value lies in ' multiple screens a cloud '. The state management of different types of terminals is already ripe, but ' cross-screen synchronization ' can only be realized in the era of cloud computing. "Li Zhijian said.

"We divide the cloud into a life cloud and a working cloud," Li Zhijian said, introducing the prospect of cloud computing applications. The cloud of life, Apple is a successful model, in short, entertainment first. The work cloud mainly refers to the corporate cloud and the government cloud, both of which have workflows in common. The role of the enterprise CIO will change, and the company will oversee the operation of the cloud through a quality assurance agreement, rather than managing it deployment operations within the enterprise as it is now. ”

Li Zhijian also mentions that many places have proposed the concept of "intelligent City", under which government public services such as education, medical care, transportation and urban management can be moved to the "cloud", especially the "Education cloud", which is a promising area for the government. As for the e-government part of the government, the government can first classify the content of the information in a confidential and open format, and then construct the "mixed cloud" setting, which is based on the management of user rights.
