Three battles behind the double 11: high concurrency, illegal production and logistics

Time:2020-7-30

Scene Description: Double eleven, a crazy social phenomenon, has entered its eleventh year. Numerous consumers are busy buying and buying, but in the eyes of businesses, in addition to ensuring that everyone can enjoy the benefits of the double 11, there are three wars waiting for them.

Key words: Double eleven high concurrent black industry intelligent logistics

It’s another double day of the year.

Numerous social issues have been discussed, such as consumption upgrading, delicacy and poverty, consumer loans, live online celebrities, bringing goods to talent, rejuvenation of domestic products, etc. the whole double 11 has become a major event in which all sectors of the society actively participate.

This consumption carnival with the participation of the whole people has become a special social phenomenon after ten years. And behind the huge consumption carnival, there are many silent contests.

Transaction data or water injection, high concurrent water

According to the report of tmall, this year’s consumption level and the speed of goods grabbing have broken new records. But soon, some netizens on the microblog said that the final sales of 268.4 billion yuan of the whole station were obviously flooded.

The netizen fitted the sales data of double 11 for ten consecutive years from 2009 to 2019, and got the result that the actual production data is almost perfectly distributed on the cubic regression curve, and the fitting degree is more than 99.94%, almost 1.
The data is too perfect, so he asserts that in order to attract the shopping enthusiasm of double 11, Ali has artificially modified the sales data, and there is a false fact.

Tmall also quickly made an official explanation and accused the netizen of being too arbitrary.

  • Tmall refutes rumors of data fraud on Weibo

Other netizens will no longer delve into this incident, after all, these figures are not important to ordinary people. The same is true for the Internet circle. The business model and technology created by e-commerce platforms together are worth exploring in detail.

At this year’s VLDB 2019 conference, Li Feifei mentioned in his “cloud native database systems at Alibaba: opportunities and challenges” that Alibaba announced at double 11:00 in 2018, the instantaneous traffic of Alibaba database background reached a record high.

“At the moment of double 11:00, the transaction volume of Taobao’s whole network rapidly jumped from thousands of transactions per second to 490000 transactions per second, an increase of 122 times, while the back-end database needs to bear 70 million visits per second. “

This year’s order peak set a new world record of 544000 transactions / second.

In order to cope with this kind of concurrency and successfully complete the payment process, whether it is Alibaba, Jingdong, Netease or other e-commerce platforms, they have to develop their own databases, conduct full link pressure testing in advance, and work overtime as if they were facing a big enemy.

The server of e-commerce platform should bear the data pressure from the instant eruption.

Therefore, in the eyes of engineers, from the first second of double 11, it has directly evolved into a war between consumption limit and technology limit.

Double 11: also the carnival of black production

Each time in the consumer shopping carnival, but also the online shopping platform is the most affected by the black industry moment.

The common specific means of profit include: embedding software to secretly deduct phone charges, maodang maliciously weeping wool, malicious push advertising traffic cashing, mobile app distribution of malicious software, mobile phone Trojan horse brush, blackmail virus attack, DDoS attack, etc.

For example, during the 618 period of tmall not long ago, similar systems successfully intercepted 50.2 billion malicious attacks in 18 days.

  • The output value of the entire Internet security industry is only 50 billion yuan, but the black ash industry has taken more than 200 billion yuan

Experts in the industry estimate that only Chinese mainland has 2 million employees in the network black industry, most of whom are young people who are 16-28 years old and lack legal knowledge. In the whole country, at least 200 billion assets will be collected by illegal property every year.

At present, the e-commerce platform can achieve that the system has completed hundreds of security detection and technical protection within 0.01 seconds of consumers placing an order, which can effectively combat the invasion of black ash products.

The system covers hundreds of business scenarios, such as fake goods identification and prevention, commodity compliance audit, business environment management, malicious flow cleaning, intelligent logistics, new retail security and so on. It can realize automatic decision-making, intelligent confrontation, real-time processing, and accurately identify the black ash production behavior.

  • Algorithm used in Ali strike single risk control system

But the road is one foot high, the devil is ten feet high. In the face of huge interests, some gangs have gradually formed cross-border crimes, using new technologies such as artificial intelligence to commit crimes and evade attacks.

For risk control and early warning, new technology is not omnipotent in the network battlefield of black industry struggle, but it is absolutely impossible without new technology.

Man machine war of express delivery

In addition to ensuring the safety of online shopping and the issuance of preferential subsidies, a large number of logistics orders after the rush purchase have become a “nightmare” for the express industry.

  • The workers are dealing with the stacked packages

According to the industry forecast, it is estimated that the maximum daily handling capacity of logistics will exceed 500 million pieces during the double 11 period, which is a great challenge for logistics.

In the actual situation, the automatic express sorting robot, as early as 2017, has gradually become the main force in picking goods on the double 11 battlefield.

  • The blue automatic picking robot can easily hold up the shelves

In the intelligent warehouse, the automatic sorting robots like small boxes have built-in AI systems. They can automatically identify packages, then hold up goods or shelves, and deliver them orderly to the designated location according to the appropriate path of automatic planning.

The most important thing is that hundreds of AGV robots can work coordinately, do not interfere with each other, and can automatically find the way to charge.

  • Robots send small packages to different storage locations

According to the introduction, these smart robots are mainly responsible for sorting, moving and packaging goods. They will take the order box to the designated area of the shelf to pick, move the shelf and find the order box to load. Then cooperate with the staff to complete the delivery of the package.

Maybe the 9.9 parcels of baby you snatched were transported by these robots which cost hundreds of millions of dollars.

The use of robots can greatly improve the efficiency. In general, using robots to sort in a smart warehouse can save about half of the labor for express delivery companies.

Behind consumption: the cause of desire and the result of Technology

Whether you chop your hands happily and regretfully, or whether you are calm and indifferent, the data show that the whole society is being promoted by the double 11.

Throughout the double 11, consumers chose from the shopping cart, hesitated and fought against the shopping desire; the front and rear engineers of the e-commerce platform fought against the national consumer impulse, the servers and millions of mobile phones; the global underworld gangsters and e-commerce security teams fought back and forth in guerrilla warfare.

These unique phenomena also promote the birth and development of more technologies indirectly or directly. I don’t know what surprises and fright will be brought to the whole society in the future.

But in these wars, there are no permanent winners or losers.

Summary of import and export usage in JavaScript

import import 和 require 的区别 import 和js的发展历史息息相关,历史上 js没有模块(module)体系,无法将一个大程序拆分成互相依赖的小文件,再用简单的方法拼装起来。这对开发大型工程非常不方便。在 ES6 之前,社区制定了一些模块加载方案,最主要的有 CommonJS 和 AMD 两种。前者用于服务器,后者用于浏览器。ES6 在语言标准的层面上,实现了模块功能,而且实现得相当简单,完全可以取代 CommonJS 和 AMD 规范,成为浏览器和服务器通用的模块解决方案。也就是我们常见的 require 方法。 比如 `let { stat, exists, readFile } = require(‘fs’);` 。ES6 在语言标准的层面上,实现了模块功能。ES6 模块不是对象,而是通过export命令显式指定输出的代码,再通过import命令输入。 import 的几种用法: 1. import defaultName from ‘modules.js’; 2. import { export } from ‘modules’; 3. import { export as ex1 } from […]
