The last few days of "Singles Day" Curtain, technical summary and the debut

Weibo, @IT program apes released such a long microblog, to see the various technical personnel to support the shopping carnival's IT architecture and operation dimension discussion. And in the American Programmer's Forum, it seems that hackers have only known China for the first time, as well as a magical company called Taobao. (to a large extent, this is because they are too unfamiliar with China.) )

What do the peers think? Today (November 14) noon, Jingdong Mall senior vice President Lee issued a micro-blog said: "Taobao technology is being deified."

followed by the technical director of Clove Garden, formerly in Alibaba work Feng Dahui "Spit Trough":

Jing Dong's friends said Taobao technology by myth, there is a myth? What I see is to do a part of the speech, and the various departments are still reflection and improvement. Ali Technology today's results, or from the attention of technical personnel. In contrast to Jingdong? Where is the technician's position?

Many people know that although Liu is a sociology major, he learns to write code in his spare time. He set up the IT architecture at the beginning of Jing Dong. Ma Yun, on the technology is not a Greek. So, why is half the technical origin of the Liu, in these years of development how to let technology become the bottleneck of Beijing East?

The expert sees the doorway.

A problem that was known in August last year (2011). Below, a lot of people in the industry on the Beijing-East technical status and reasons ("Why Jing Dong is still in use.") NET architecture? ") has been discussed. Several a similar view is: Liu understand technology, but the lack of a real technical foresight of the CTO to strengthen the technical perspective of Liu, so jingdong in the rapid development of the way to use it the first set of architecture, the results all the way bungled.

Tian Product Network CEO Big Bear said:

Lao Liu said his technical background, but I actually turned over the old Liu's own resume is probably just 10 years ago did some financial system and small enterprise application system, after the Internet technology and high concurrent flow under the application environment, I believe that Lao Liu has been very unfamiliar. His own thought of "Understanding technology", I think is precisely the development of Jingdong technology has not been the biggest obstacle to progress. Also led to the capital of Beijing and east of the main reason for the investment logistics. On the online technical capabilities and Web site support structure, the Beijing east to fill the homework is too much.

The latest news is that Beijing east recently in the fierce Recruit technology research and development of Daniel, presumably to switch to Java architecture. With such a large amount of traffic, it should have been done by 2010, and it's too late to do so.

Feng Dahui also spoke under this question,

First of all, language is not the most critical, I believe that with. NET, with Php/java, can develop a very cattle site. But the difference between the person who uses the language and the technical team that makes it is too big.

It is said that Jingdong Lao Liu was the earliest to write code, it is estimated that the use of Microsoft's technology to write things. The first engineers were also expected to work with Microsoft technology, and these people as the company's strength, gradually someone to take power, which formed a situation? The discourse power belongs to the people of Microsoft System. Even if someone wants to use other technical system to do something, it has to face a lot of resistance. "Habit" is difficult for a team to change, unless pushed down from the top, but this is too risky. Plus to keep up with the pace of rapid development, then keep running. See that electric bike on the curb? Very flexible, fast enough to run to 40, but really dangerous.

In other words, Jing dong activities are very embarrassed, is the ability of operation, architecture design, the level of the underlying data is not enough. In fact, trading volume and not many pens, compared to some pure trading site is too bad. A few years ago with the people of Jingdong exchange once, found that the consciousness and technical reserve is really and their reputation does not match.

In the final analysis, Beijing East has been developing too fast in the last three or four years. The original technical framework has not been able to match the current development, business development is more than expected and technical planning, and in the high-speed road to change tires not overnight.

In a report on Liu by Patrick, a journalist at Businessweek, he wrote about how Liu and Lee suffered technical distress at the end of the 2011 book Sale:

Jingdong's first IT system was developed by Liu, and by 2008 it was not enough. Jing Dong Senior vice president Lee with more than 10 young people even dozen 3 months of the floor, sleeping three or four hours a day, redo the system. The system is designed to be a daily average of 100,000, at which point the average daily order was only 5000. 100,000 alone is a terrific number in their eyes. November 1, 2008, the new system online, daily orders immediately rushed to 10,000 single. The 2011 peak was 500,000 single, exceeding the design of the system. Lee again to make the structure adjustment, according to the plan will be completed in 2012 Spring Festival. However, November 1, 2011 Book time limit 3 hours of promotion, many users will buy the book in advance into the shopping cart, when the event to submit an order. such as flood discharge, instantaneous flow, to 100,000 single seconds, the system can not distinguish the book inventory, the user will not be able to continue to brush inventory, the system has been paralyzed. Liu has two knives and two cups of tea on his desk, please be responsible for the IT front-end Lee, the vice president of the IT backend Jiang Haidong tea. The main responsibility of the Lee outside business, escaped a robbery. When he returned to Beijing, he went to Liu Place to Lingzui. June 2012, Jiang Haidong quit.

"We have a fast-growing desire for business, but technology is the bottleneck," Lee said. "I am the equivalent of changing tires for a speeding car, which is my biggest challenge." "At the end of April 2012, the new system on the line, design capacity is 10 million single, Lee estimated 3 years without problems." When he went to Jingdong in 2008, there were only 20 people in the IT department, and now there are more than 1800 people, who will expand to 2800 by the end of the year. 2012 Beijing East in the IT research and development, server and so on cost is 1 billion yuan.

January 31, 2012, Jingdong Mall Weibo announced that the original Oracle Global Vice President Wang Yaqing joined Jingdong Mall, became the first CTO (Chief Technology Officer). According to the Beijing-east side, Wang Yaqing will promote the integration of IT technology with the existing industrial sector, through the integration of existing technologies and platforms to establish a unified technology direction and data structure to improve the stability of the overall architecture. This means starting from the Liu start-up period. NET architecture, to formally turn to Java.
