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!
@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.
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!
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.
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.
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 ❤
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
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.
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.
I clicked on this vidéo to understand how to manage big data, like trillions for example. Well at 11:40 you start talking about it but you never really explained how to handle such a huge amount of index, I'ld have like some stuff about load-balancing, and other tech used :( . Except from that the quality of the video is great and it's a good introduction to big data management.
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 :)
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! 🔥👏

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..
if ppl complain about long waiting times.. just put a mirror in front of them . that will keep them busy until the elevator arrives
As backend engineer, I truly love this video.
Legit

the worst part is not no of lines but the flow of the functions and their calls

Thank you 🙏!
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!
This is master piece, the story telling, the animation, the tech, the way you deliver, good job man 👏👏
Dude, this video is amazing not only from a storytelling POV but also the in-depth detail! Your animation / video editor killed it!
This is the first ever video I’m watching from your channel and man …. The production quality blew me away .. good job man. Subscribed🎉
Lewis you took this to the next level!!! Love the animation, SFX and the storytelling. This one really grabbed my attention
I had to move from PHP to node+express. That was a violent transition.
But now feels peaceful
Brilliant work by the Uber Engineers because when you deal with Uber data volumes you're in your own league

This video was on a whole new level!!! I can’t believe that you improved so much!!
Babe wake up, Lewis just cooked
I learned more from this video than from many college lectures.
This editing style is the best I think I've seen in my life
Yes, thanks to Uber for donating their process.
Great video. Deserving of the animations.
This is the one of the most informative and useful information you have shared. Thanks.
Fun fact: public blockchain are triple entry ledgers.
6:47 Holy Sh*t! The quality of these videos is going crazy!
The animations are really sick, so well made for someone who has just intermediary knowledge in dbs this is super helpful...
The Animations Are really cool on this one dude
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
This is amazing. It’s tru, we take it for granted. What an amazing approach ❤
Story telling and animation is amazing 🙌
I love it when you say: The Shadow Writer
Educating, Engaging and Entertaining :) Great work mate!
i totally enjoy your engineering analysis videos💯
I took voluntarily took two accounting courses in college and never regretted it!

The narration was so interesting. I read the article once but was not really able to grab it
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
Of course a company no one has ever heard of will give the Uber system design as an interview question
Another great video keep going man!
This video felt very hypnotic to watch
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
Great video❤.
And the quality and animations are awesome, can we get a video of this animation workflow sometime. Would love to see it.
Great stuff, man. Awesome!

Time to give your video editor a raise
the fact, migrating big database in production is so challenging.
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.
great video, thanks man!
Underrated account
Who in the world does your animations?? Fire 🔥🔥🔥🔥
nice traditional design
the challenge lies in the creating a system which is consistent and efficient.

@@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.
What site do you use for ai video animation/characters creation or it's made from scratch in Adobe AE.
