The price war highlights the difficulties of it technology and the escalation of power companies

Major paralysis, the power of the Web site can not withstand the pain

This round of http://www.aliyun.com/zixun/aggregation/7869.html "> Electric business War of the smoke has not dispersed, people seem to be still entangled in the electric company whether the real make concessions." However, for the electrical appliance companies, although the competition is fierce, but at one point there has been a lot of growth, that is the amount of user visits.

It is understood that in the electric business World War, the flow of Jingdong in the normal 3 times times, Suning easy to buy 10 times times, and Gome due to lower base, traffic is more than the usual ten times. Electric companies of course want to see a large increase in traffic, but for the background of the Electronic Business site system, the number of visits is a big test.

Last year Jing Dong 618, the site was once paralyzed, which led to a large number of consumption of the Beijing-East complaints. Jingdong CEO Liu had to announce a doubling of the server and extended promotional time. This year, through the purchase of servers and improved technology, Jing-dong successfully spent 618.

But in this round of electric business war, Suning was once unable to access the purchase. Obviously, for the sudden action initiated by Jingdong, Suning's easy to purchase has been challenged in the server.

According to industry sources, if a big promotion, in addition to the supply chain need to prepare several months in advance, in the background of the site also needs several months of adjustment to cope with the surge of traffic. If traffic grows several times overnight, few companies can handle it.

But Amazon, the star company of the power business, is rarely dragged down by servers that make it inaccessible. It can even take advantage of its own servers to provide technical support for other small and medium sized sites, although the service is sometimes less stable.

For Amazon, the solution to the site access, to ensure that users have a smooth purchase of the next single is not a problem. Amazon is more likely to make accurate recommendations through technology, allowing users to discover more of what they might need.

Of course, it may not be fair to compare domestic electricity with Amazon, but an undeniable fact is that domestic electric companies must begin to pay more attention to technology.

Ensure the stability of the site is the core

If we want to measure the impact of technology on the electricity quotient, there are three main aspects: reliability, Unit cost, and suitability for future development.

One of the most basic is reliability. Reliability refers to the proportion of the site can normally open, according to the domestic electric industry veteran Personage introduced, to the electric business website, this kind of stability generally to reach 99.99% just, "Now all in spelling the decimal point behind a few 9". Because now all major electric power website is doing open platform, then stability also contains its open platform business system stability.

At 618 last year, Jingdong had a big problem with reliability. Industry insiders believe that this is in fact the technology of Beijing east over the years accumulated problems of the outbreak.

It is understood that because of the large number of jingdong used. NET technology, and this technology is not suitable for any time need to expand and adjust the large web site. Open source Linux and Java may be more appropriate for large web sites.. NET for Microsoft all, use the words need to pay a certain authorization fee, and all kinds of adjustments are very dependent on Microsoft, Linux and Java is more suitable for expansion, and the site can be more autonomous adjustment.

In addition, in the recruitment of technical personnel, Java programmers now more, and. NET programmers are relatively few.

It is not easy to go from. NET to Java. A technician on the Web site says the shift is about changing the structure of some data, such as data on user history orders. "originally used in the. NET is a format, but in Java to use B format, this data format modification is cumbersome." And the people who are recruited are not necessarily directly available, they first have to familiarize themselves with the original system. ”

But if it doesn't change,. NET technology has been difficult to adapt to the rapid development of the Beijing-east demand, the only solution is to buy a better server, which increases the cost of pressure, but also not the Internet company practices, internet companies tend to use the general server, through the system to stimulate the largest server performance, Google (Weibo , and other international companies such as Amazon.

Domestic well-known technology blog Cool Shell founder, Chenhao, the operator of electric business, said that the purchase of more servers can solve some of the problems encountered, but the premise should also be designed to the system can be extended horizontally, otherwise, if the design of the system is too coupled, can not split the system into various subsystems and achieve the goal of horizontal expansion, I don't want to add the machine. In addition, the system architecture also to support the distribution, and according to their own business to do some asynchronous services, data partitioning, reduce business coupling and complexity, or even add a machine, the complexity of the business can not play the biggest role of the server.

An Jingdong technician said Jingdong in 2012 on the technology of the transformation of the core is "distributed and fault-tolerant", with a distributed solution to a single point can bring performance bottlenecks and potential problems, that is, the whole system does not exist single point, even a few computer room power, even if it is a certain machine or a few machines crashed, Has no effect on the user. This will better protect the user's smooth order and the background of warehousing, sorting, distribution, after-sale system can successfully complete the life cycle of each order

The most obvious phenomenon is that this year 618 Jingdong flow is 3 times times last year, but also faced with serious DDoS attacks, but the site did not appear any problems.

But this shift in Jingdong is not entirely dependent on technology. Earlier this year, Jing Dong introduced the original Oracle, Vice President Wang Yaqing as its first CTO. According to the industry, Wang Yaqing came to purchase a set of 100 million yuan from Oracle's system, some of the core technology has been upgraded.
