今天這篇文章探討的是 Uber 內部的架構以及系統設計。
Uber 最初是使用 Python 作為開發語言,並且基於 monolithic 的架構來開發前後端。 2014 之後,Uber 將架構給轉移到 service-oriented 的架構。
Uber 的業務(Taxi,Eats)基本上是一種 Demand <---> Supply 邏輯的業務,以叫車服務就是如何將叫車的使用者與開車的司機給媒合。基於業務可以分類出系統需要兩個服務,分別是
Deman 服務以及 Supply 服務。
這兩個服務會串接系統內的 DISCO(Dispatch Optimization), 該服務基於 Map&Location 等資料來進行處理,但是這兩種資料搭配經緯度要處理實在麻煩,因此該服務使用 Google S2 函式庫來處理。
文章中介紹非常多 DISCO 如何處理地點相關的資料,如何有效率地幫司機跟使用者給媒合,有興趣的可以
點選原文閱讀。
除了媒合系統外,文章中還介紹了如何處理 Payment fraud 這類型的問題,全文非常長,有興趣的可以細讀
而這邊列出文章提到的各種專案
1. PostgreSQL -> MySQL (文章中有另外一篇連結探討為什麼轉移)
2. RDBMS/HDFS
3. KAFKA

Yandex is Russia's biggest tech company
Founded in 1997 or 23 years ago by a businessman named Arkady Volozh
Yandex stands for Yet Another Indexer
Because the first business of the company is to make a search website.
In the global Search Engine market, Google is undoubtedly leading up to 92 % while Yandex has 5 % user with a 0.5 % share.
But within the Russian country
Yandex can rule the market share at 58 % to be regarded as Russian Google.
However, this is only part of the Yandex Kingdom because of 70 different types of internet-related businesses.
Let's see some interesting examples.
Yandex. Direct Online Advertising Business is like Google Ads. 61 % Russian market share.
Yandex. Market platform to buy products online like Amazon. Currently, there are 19 million users per month.
Yandex. Taxi platform called Uber, but embraced 60 % of domestic users until the end of 2018, Uber competitors have to sell Russian affairs for 36.6 % of Yandex's shareholders. Taxi instead.
Yandex. Eats food delivery service and Yandex Lavka, the new generation's popular grocery delivery service.
Resulting in quarter 1 2020 Transport business group grew 49 % compared to the same period last year.
Yandex. Music platform listening online like Spotify and Yandex. Video platform. Video watching online. Like YouTube. Latest. Total members of 4.3 million accounts.
There are also many other businesses like
Yandex. Flight Platform to book airfare
Yandex. Messenger Chat Apps
Yandex. Disk storage services on cloud
Yandex. Money Payment System and Online Banking
Alisa Smart Assistant like Amazon Alexa
Even during the COVID-19 incident Russia was one of the severe outbreak centers, the company developed a free virus detection kit to the public.
By the proportion of the company's income every 100 baht.
64 baht from advertisement fee
24 baht from car and delivery business.
12 baht from other businesses such as subscription fee, entertainment media.
If you ask what is the reason Yandex has succeeded in occupying online space?
The answer should be not hesitating to grab opportunities in hand.
The company's strategy is to analyze which businesses have potential and foreigners are starting to market. But it doesn't meet local people. Yandex will compete with simple service models and consistent with consumer behavior.
Because the company has a great advantage that it can design platforms to support the usage of Russian language properly and more accurately.
Improving Yandex's performance continuously following the development of internet technology.
But it's undeniable that the weakness of rubble currency from Russia's case of economic sanctions since mid 2014's after Ukraine Crimea land annexation to be part of itself. Assembled with the Expanding businesses, affecting fairly corporate profits.
Year 2013 (1 rubles equals 1.01 baht)
Income 39,900 million baht
Profit of 13,600 million baht.
Year 2017 (1 rubles equals 0.55 baht)
Income 52,000 million baht
Profit of 4,800 million baht.
Year 2018 (1 rubles equals 0.47 baht)
Income 60,000 million baht
Profit of 20,800 million baht.
This year, there is extra profit from separating Yandex business. Market venture out with another company
Year 2019 (1 rubles equals 0.49 baht)
Income 86,000 million baht
Profit of 5,500 million baht.
Yandex is listed on the NASDAQ stock exchange in the USA. Now it's worth 420,000 million baht.
And it is evaluated that Mr Arkady Volozh, who is founder and CEO has private property up to 42,000 million baht.
However, sometimes business-related to a lot of data is often troubled because government concerns about the security of important data that could slip into the hands of dissent countries.
Yandex was recently ordered to restructure the company without a single shareholder over 10 % and limit total expat shareholders to 50 %
Yandex story makes us know
In many countries, strong foreign brands often scare local business owners and dare to do anything.
But really, what those companies can fight with us is understanding the unique characteristics of domestic consumers.
So if you keep opening the door to opportunities.
At the end we may succeed.
Like the case of Yandex that has become everything in Russian life..
