How Uber Handles TRILLIONS of Transactions

[@CodingWithLewis]

Thank you for 600,000 subs! This is by far the most ambitious video we have made! Thanks so much for letting me do this as a job. What content would you like to see?

I heard that a great deal of Uber's success actually came down to their map feature. Apparently, the inspiration was from James Bond - specifically the movie Goldfinger, where James Bond has to track Goldfinger's car. He has a map feature on the dashboard of his Aston Martin, which shows his tracked target as dot that moves along. Psychology says that people don't like waiting very much, but if they know exactly how long they need to wait, they feel better doing so. Uber really found a gap in the market and went for it.

James Bond does it again

[@cocoasulphur]

@@CodingWithLewis And to think, James Bond never even went to Oovoo Javer

[@nonefvnfvnjnjnjevjenjvonej3384]

i mean really the reason they grew is because they were cheaper than cabs due to vc money and cabs used to scam people.

[@Sammysapphira]

This is really odd, nor is it particularly a genius insight. Uber didn't invent tracking on maps.

[@YoKKJoni]

theres the same trick with ppl and elevators.. if ppl complain about long waiting times.. just put a mirror in front of them . that will keep them busy until the elevator arrives

crazy animations

This is master piece, the story telling, the animation, the tech, the way you deliver, good job man 👏👏

[@nickcolleran9212]

I died at the beginning when you said “a Lyft from one place to another”. Even though it clearly wasn’t intentional it still made me giggle

[@normb9785]

Lewis you took this to the next level!!! Love the animation, SFX and the storytelling. This one really grabbed my attention

[@chiroyce]

oh my god i cant even begin to imagine how the code for this must've been, thousands or even millions of lines spread throughout thousands of services and systems all for a car ride 🤯

Huge respect to the engineers on Uber that made these possible. I can't even tell how scary migration from a database to another on PRODUCTION is. Thanks Lewis ❤.

@CodingWithLewis Nah you do all that while doin programmin. I can't even only do programming lmao. Even though I hate Python developers, you shall be the one I respect.

[@BangladeshiUser-k4w]

Thank you very much for this quality content. I've seen many videos on how big tech companies are scaling their projects. But there are no quality video on how to do it by yourself, or I couldn't find one. I'd like to request you to make a video on how you would scale a PHP project with MySQL database. That video might cover, how you would tune your MySQL config, php-fpm pool, nginx worker, linux itself for handling files, cache leverage, slave db etc. Overall preparing a project for being production ready to handle huge traffic with low latency. That would be a great video. If you make your mind to create such video, I can't wait to see it. Best wishes ❤

Liked the script, the pace, the tone, and the technical details. However as other have said, the animations were too much and made it sometimes hard to follow as they were too distracting. However, I appreciate the rest, and the time that went into it. Just subbed!

[@CDHDeveloper]

Very well done Lewis, even compared to your usual grand presentations.

[@timothynwanwene4378]

Can You explain how one backend and database can work seamlessly with web, mobile, and desktop applications, *React for web, Flutter for mobile apps, React Native for desktop, Django as the backend, and MongoDB as the database?

Was better to go and investigate what and how Uber make money, what profits declair and how much money they realy making, how they are enjoing to steal as much as they can from clients,customers,riders,drivers. IF YOU START DOING THIS I will help you❤

[@yassinesafraoui]

The animations are all fun and cool, but I think they're getting in the way of information transfer by oversimplifying concepts, use them carefully please, even though the more you add the cooler the video looks and the more views you'll get

[@heybropro175]

why did you pick uber specifically? just curious

[@knowledgeworld2233]

can you make a detailed video of the India UPI system

really informative

Skill issues and tech debt in a nutshell. Do you think VISA would have less transactions than Uber? They held up perfectly fine without a hiccup.

[@sumitrathod8062]

Can you how indian UPI system works

[@matheesha-ls]

I have ordered food from uber eats like 5 times now and about 3 times when placing the order the amount is held from my bank account but after delivered i will receive the funds back and will only charge the tip amount. It will try to charge the amount of the food after like 10 days even when there is no money in the bank account. But i deposit the amount of the order to my account so it will be charged later.
