Dawning Nie Hua: promoting data fusion

To be located in Beijing, outside the five ring Zhongguancun Software Park, the Dawn building, here away from the urban area, due to the time of work, the park is only occasionally a vehicle passing by, see the most is the security guard at the entrance of each company. See Nie Hua is in his office on the five floor of the building, right here we talked about the dawn and cloud computing.

Cloud computing is not a bubble

CSDN: What do you think of the domestic cloud computing market?

Nie Hua: It technology is what we call a popular technology, it is not like physical chemistry of this basic subject research, it concentrated in the hands of a few people, can do very profound theoretical research. After the popularity of cloud computing technology, although seemingly very simple, but it needs the background of a huge technical system to support. The simpler the performance, the more you need an invisible hidden technical system to support it. Speaking of cloud computing is easy, I believe many officials now say cloud computing is very theoretical and theoretical level. But in fact to operate and support cloud computing, or to have a strong technical background in the industry to support the company.

CSDN: There is a view that cloud computing has too many bubbles, what do you think?

Nie Hua: From the market concern, cloud computing is not the pinnacle of brilliance, began to go down, this is also fully in line with the hot attention curve, from the early rise to the peak, gradually some doubt, leading to its fall. No matter how you query cloud computing, you will find that the United States IBM, HP so many large enterprises are pushing cloud computing, our entire computer industry or industry experts are talking about cloud computing, it is not a pure bubble, or purely conceptual. If a purely conceptual, maybe a scientist talk, a team talk, a business talk, but if the world is talking, it still has a certain consensus.

Dawn Drives Data Fusion

CSDN: What bottlenecks does domestic cloud computing need to break?

Nie Hua: The most perfect thing about China is the Top-down vertical system. For example, when we talk about urban cloud computing, why do we need data fusion? In a city, you will find that the police population data is vertical, family planning data, education data, social security data is vertical. But if these data are not fused, the overall effect on a city is much smaller.

China now has a big problem is that a common people in access to information services, access to information services in the industry is now increasingly convenient, access to cross-sectoral information services is now increasingly difficult. For example, Beijing needs to assess whether you are eligible to buy a license plate, and you will find that information is circulated between departments for one weeks.

One of the successful voter registration cases in Yichang, which includes not only the household registration, but also the floating population, is not entirely based on the household registration, and this information cannot be transferred from the Public Security bank. Screening voter registration, many cities generally take 30 days, we registered in Yichang only two days. Why only two days? Because through the registration of the population and the floating Population Data association, to achieve all-round management, but also the use of information tools, grid in front of the effective real-time capture of data, which is what I call cloud computing and information, or we bring you a value.

For example, it can be estimated that a school should check how many age-appropriate children are enrolled in the vicinity. In fact, we socialized management to a certain extent, each department through the information to make the right judgments. How many people are there in my physical administrative area, how many children are in my neighborhood, and our ID numbers contain age information. Even those who are in the population and which are going out with their parents is the value of information fusion.

CSDN: What is the value of dawning in data fusion?

Nie Hua: Data fusion involves the government's information resources, the dawn is a very suitable manufacturer. Because of these resources, some information is confidential, to be managed according to the national Secrecy law, some information is sensitive, is to be protected according to the level, according to various protection means to deal with, and the data ownership or Government management department. Foreign companies do not have this ability, because he involves sensitive data, confidential data processing, from information security, national security is very important. Lack of technical capacity of enterprises can not do, small enterprises if you can not get a government trust, do not dare to give the data to you to deal with, he can not do.

Cloud computing security is a challenge

CSDN: How to ensure data security?

Nie Hua: Cloud computing poses a huge security challenge, a proposition that everyone recognizes. Without cloud computing, security issues are not so prominent, why not so prominent? First, the data is small and easy to protect; second, the data is relatively closed, closed and easily protected. But after the advent of cloud computing, the first requirement is a large concentration of data. Second, the integration of data to form a strong support. Third, the application of the pull, you will find that the past want to do things you can do, with the internet of things, after the acquisition end to strengthen the data explosion rapidly. A lot of data, single data is not sensitive data. For example, collect 20 person's ID number, this is not sensitive; We usually exchange business cards, collect 100 people's business cards are not sensitive. But if all the business cards in the city are collected together, the identity card numbers of everyone in the city will become a sensitive information. Because this information can be associated with a lot of related things, this is the challenge of cloud computing.

When the data is large and the data is blended with each other, security issues arise. A battery in a power plant, its safety is easy to control. But when the entire American grid was linked together, a small accident could cause a blackout in most of the United States, which is also the spillover effect of cloud computing, which we call cloud computing security. Because of the full association, the boundaries are unclear and protection becomes more difficult. Now there is no absolute security, first of all, we rely on the laws, regulations, we have a computer information system security rating protection, evaluation, the establishment of a secret personnel management. This is where security comes from systems, from management, and from your trust in people. Security issues, professional things have to be given to professional people to do to be safe.

Cloud computing and green energy conservation

CSDN: How to make cloud computing greener and more energy efficient?

Nie Hua: Energy-saving now has two challenges, the first challenge, as our data center design is more and more large, hope to accommodate more equipment in a certain space, this will solve the problem of how the heat from the local dispersed; The second challenge is that the high Performance Computing data center is extremely bloated, Now a 1000 times-fold power explosion in a data center is a very real problem. How to deal with these problems less energy, or less energy consumption. We have a lot of software technology, hardware technology to improve efficiency, the Ministry of Science and Technology will immediately reply to the issue of Cloud server, I am also a project leader, which will propose an indicator: under the same processing capacity, 2015 than the current general server energy consumption reduced by 90%.

We have done research, a packet on the internet to let the CPU to deal with, at least two copies of memory inside, the CPU will be a lot of interrupts. Like this kind of thing, to a certain extent, is how to solve, that's how we're going to solve a same data processing, the same Internet response processing, how to reduce through a good architecture, through a lot of invalid parts of a reduction, through some efficient parts, through some technology to reduce intermediate, how less heat, This is a direction.

The second direction is how to let out the heat and cool it in a natural way. For example, many cities in the winter is the natural heat, some local water resources, some places have other resources, how to make full use of natural resources to solve the heat dissipation of data, can be less consumption. Of course, it is now facing a very serious problem, cost problem.
