Beyond "virtual Beauty"--Analysis of cloud computing practice

Guide: With the fourth session of the cloud Computing conference curtain, three days too many wonderful innovation and sharing impact on us, CSDN will be a wonderful share of the instructor after finishing processing to provide readers. Today brings is the Chinese Electronic Society cloud computing Expert committee chairman, Chinese Academy of Engineering academician Li DEII in the Cloud Computing Conference keynote speech, CSDN collation as follows:

Cloud computing is maturing and big data is growing

After the understanding of cloud computing, has become the main theme of the current information and communication industry. We can use Wikipedia to take a look at the current understanding of three important technical concepts. One is the grid computing that has been confusing with cloud computing, and one of the big data that's developing, and let's take a look at Wikipedia's access to grid computing terms, the term "cloud computing" and big data, and see how the world is concerned. Grid computing in the April 2008, the focus of human attention reached 69,573 times. Cloud computing reached its highest hits 751,383 times in December 2011. Large data has not been reflected in the number of views, because it has just arisen, so we have to change the ordinate measure. Big data is being developed, reaching 58,888 times in March 2012, which means that the world's focus on these three important concepts is our group behavior. This group behavior if we use a famous consulting firm Gartner in the 2011 curve to prove it, he called some technologies mature technology, some technology is expected to mature technology, is considered to be 2-5 years of technology can be used. While big data is on the rise, cloud computing is booming, and grid computing is no longer in sight. This technology, from the rise to the boom to maturity, can be expressed in terms of objective rules, which support my title, from the rise to the boom.

Why mention Big Data? Let's take a look at the changes in the amount of data that the world's human perception of matter and energy has created. In the 1993, a lot of information is in the virtual state of existence, that is, the mass of human information or simulation has not been digitized. By 2000, the digital component gradually increased. By 2007, almost 90% of human information was digitized. In this case, large numbers appear. Big data in English, this level tells us a knowledge, he said is the PB era of data, PB era of science, so we need to understand the relationship between large data and cloud computing. We are all more familiar with the database or data warehouse technology, we have used a very long time database, data Warehouse in front of large data to meet what challenges? We can take a look. First, we look at the amount of data, in general, the database or data warehouse in gigabytes, or to TB level, and large data is in the TB or PB level, which is the difference in data volume. Strictly speaking, this quantity is not the root of the problem. More importantly, when we put all the information into the Data warehouse, the data requirements are relatively high quality, relatively clean data. The data we encounter in real life, most of them are noisy chaotic state, placed in the database is difficult to mature.

In the database and data Warehouse, our data model has a very strong structure, there is a data on the number of support, and large data is often unstructured, large data people often focus on video, sound, picture data, rather than pure data. If we put the data in the database, we need a data pool, so we need the top-level design when we study data management. And now we can't dig a pool to put data in, we are faced with a huge amount of data, we are faced with is to fish in the sea. In database technology, we are faced with a transaction operation, if it is a TB of data, it takes about 50 hours to do a transaction to complete, this technology is relatively heavy trading. In the big data age, we are more concerned with the interaction between people and data. For the database, we often want to get a thousand-person, more ideal point of identification, and for large data, we often need an uncertain point, a satisfactory point, which is to the traditional database technology challenges.

In this case, operators focus on cloud computing, starting to focus on data center of the large processing problems, whether it is the Mail Service center, Customer Relationship Management Center, Computing capacity Leasing Center, Search service Center, data Management Center, streaming media service center, Location Service center, Must seriously consider the problem of large data processing in a given service environment.

"We" are smarter than "me."

In the era of cloud computing, there are new challenges to the way we develop software, and we once knew that a large software company such as Microsoft, in the context of the Internet, especially the social network, has been developed with a community and society. For example, the top cooed is such a community, the backbone of the community can reach 400,000, even if a company like Microsoft, the programmer reached more than million already very difficult to maintain, a 400,000 of people's software development community told us that such a community will be a society, not a company. Future software development, in addition to the company, there is a small audience, but in this small audience can have hundreds of thousands of of developers. Top cooed works in three areas of the world's software development community. First, the software fragmentation, software coding competition, mutual Evaluation Code, System evaluation, which accounted for the top cooed community One-third of the workload. If there are many programs in life that need to be developed, we can put this development task in the form of outsourcing to the community, so that people in the community to submit the results of the bidding, in the completion of the part-time development process, our software developers, the corresponding remuneration, there are many software development engineers will not work in the company, It's a part-time job in the community. I met a student at Zhejiang University who worked as a part-time developer for top cooed, not only to feed himself but also to feed his parents. This development community, but also for companies to find talent, become a very important source of talent. Headhunters in such a community, show the status of various enterprises, staff recruitment. Therefore, cloud computing makes software as a platform for the development of more group, socialization, the formation of new development agencies.

Crowdsourcing concept, after the birth of the Internet has infiltrated all aspects of society, so that everyone can be software developers, editors, creators, journalists. So, cloud computing tells us a truth that in cloud computing forms a wide variety of societies, small audiences or masses of small audiences, and the deep cooperation between them gives us the truth that "we" are smarter than "I". Cloud computing in China, has gone through the concept of sober, operation Blurred, eight, foggy a distance. However, more and more consensus has been reached, the country has been listed as a strategic emerging industry, embarked on the application of cloud computing road. Therefore, our third China Cloud computing conference is to demonstrate the leading innovation practice as a slogan.

What is the consensus of the people? It and information service can realize socialization, intensification and specialization, the network becomes rich, the edge becomes simple, the terminal product is rich and diverse, the interaction is more intelligent. In the future, the departments will no longer need to build their own specialized information systems, so that information services become the public infrastructure of society. At this point, there is no different sound.

Cloud computing has made a big difference in our emerging-industry chain, the product-centric division of the industrial chain into a service-centric stakeholder mutual infiltration, mutual infiltration, frequent interaction, consultation and win, Huawei publicly proposed to "be happy to be integrated", they are consistent with the trend.

Cloud computing will once separated microelectronics, computers, communications, software, home appliances and other products into the three major sectors. In the early days, these sections were still distant, but the structures came together with a wide variety of data centers, computing centres, service centers, and heterogeneous, overlapping, cascading networks and diverse devices. Once computer computer products, communications, telephone, exchange, and then slowly computer to engage in personal computers, communications industry to engage in mobile phones, so that the gap between notes more and more small, now people find personalized, intelligent, portable equipment to become the technology of the masses, which led to today's three major plates, the first plate is the end equipment , there are very, very many devices, and the domestic cloud TV puts the operating system and WiFi on TV. The second part is the network and network operators, the third is the data center, computing centers and service centers, cloud computing has led to a new pattern of our industrial chain. That is, cloud computing has become the main melody of ICT industry, no longer wavering, no doubt.
