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.
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
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 🤯
I'm not gonna lie... I've been vaguely interested in programming for years, but I never felt that interested to the backend side of things. This video changed that. Great quality, and great for a visual learner. Thank you 🙏!
one thing for sure is that Uber knows how to name technical stuff. Because Shadow writer is so cool. And your animations are on point to illustrate that. 7:48
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!
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 ❤.
@@nonefvnfvnjnjnjevjenjvonej3384 On paper yes, it's a pretty 'small' amount. But look inside, you're handling sensitive user data, and BILLIONS of users' credentials can be affected with some mistakes. These migrations must be taken seriously even though it's a 'small' amount.
Amazing video and explanation. The ledger system is actually a great idea even for caching and keeping transactions data updated since we would only need to update calculations in a forward method vs traditional updates would cause a cache invalidation. Append only speeds up reusing older caches for new values a lot easier.
Have watched your videos for such a long time. Somehow, I wasn't subscribed?! Sorted that. Also - one of the best videos you've ever made. Great animations and interesting topic. Nailed it!
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 ❤
@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.
Great video I love your channel Lewis. Thank you for the awesome content. Years ago I got to experience “upsizing“ an Access database to SQL Server. Good times.
Their innovative solutions are really paving the way for seamless transactions at this scale. It's impressive how they’re staying ahead of the curve with real-time processing and security. Major respect to the tech team making it all happen behind the scenes! 🔥👏
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?
In large-scale applications, you rarely hit the actual database directly due to the massive volume of data. Instead, they use technologies like Kafka to stream data, and often employ distributed databases because a single database cannot handle the load.
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
There’s something I feel I need to add here, especially that newer devs should know. Architectures and ideas like these were not made and perfected by a single person. Great things are built by teams. You should focus on becoming good of course, but complicated things like these go through several iterations both in the idea stage and development stage. It’s done by several developers in different ranges of skill level working together. Don’t try to become all knowing, no one is :)
7:11 to synronize two same table at deffrent database i think uber come with expesive approch, why not if once the asynronuse process fail he put that data somewhere and assign some worker to check to there if there data in there they just retry to insert it to the new database, ofcors this is not complete what if otherwise happend so old database need same mekanizm to ensure two database have the data
@@CodingWithLewis the question is actually this is best practice? If you have specific requirement that does not exist yet it might be worthy but if that already exist idk.
this makes me think if uber struggled to transfer their databases, how do these big international banks do it? Where money is their biggest concern, Ive had many times where funds are missing from my bank account, only for me to call the bank to figure it out.
The simple answer just never ever migrate to another database, migrate database cost lot of effort and thought and last but not least headache, specially if you have really big data like bank companys, if money lose happened like you deposited money to your bank account and they money does not come in to your account the developer will check on your ledger this is the history like evey changes on your balance will store in here. Fun fact this video is all bout ladger 😅😂

James Bond does it again
@@CodingWithLewis And to think, James Bond never even went to Oovoo Javer
i mean really the reason they grew is because they were cheaper than cabs due to vc money and cabs used to scam people.
This is really odd, nor is it particularly a genius insight. Uber didn't invent tracking on maps.
theres the same trick with ppl and elevators..

the worst part is not no of lines but the flow of the functions and their calls
This is master piece, the story telling, the animation, the tech, the way you deliver, good job man 👏👏
My favourite scene was the one about migrating data from DynamoDB to the new LedgerStore database. It was so fascinating to watch. Great work Lewis!
crazy animations
That's the goal
That can't really be it...can it?

Dude, this video is amazing not only from a storytelling POV but also the in-depth detail! Your animation / video editor killed it!

As backend engineer, I truly love this video.
Legit

Babe wake up, Lewis just cooked
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
I had to move from PHP to node+express. That was a violent transition.
But now feels peaceful
This is the one of the most informative and useful information you have shared. Thanks.
I learned more from this video than from many college lectures.

Very well done Lewis, even compared to your usual grand presentations.
This was very enjoyable to watch! Subbed for sure!!

Great video❤.
And the quality and animations are awesome, can we get a video of this animation workflow sometime. Would love to see it.
very good topic and well done. uber is a an impressive company, it’s very difficult to operate in a tough competitive industry. i wish them the best.
Your animations are golden!!! A new subscriber found in me!!!
If you could make these level of animations for data videos, I’ll definitely appreciate
nice traditional design

As an Uber driver The example of $18 going to the driver and $2 to Uber really hurts my gut! These day $7-8 goes to driver and $13-12 goes to Uber

I wonder how big that data would be 🗿☠️

0:43 "Hundreds of billions worth of money" sounds so goofy.
Why?
@@Jykobe491 idk, "hundreds of billions of dollars" or whatever sounds better, but saying "worth of money" doesn't sound right

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.
Underrated account
editing crazy wit this one

Can't imagine building your own database solution from scratch
When you have all that investors money, you build everything from scratch
