Hello Friends,
Do like and share the video and Subscribe(Press the Bell icon as well) to the channel to get all updates.

This is my thought process of designing a system like Uber. I hope this will help you gain some insights on a designing a system like this and also help you in answering interview question related to system design.
Do put in comment section any doubts that you want me to clarify.
Also let me know things that you liked and disliked about the video.

Let me know if you were asked some system design question in an interview and you got stuck, I will try to come up with a video for the same.

are u amit bharti ?

According to CAP theorem, system cannot be both consistent and highly available at the same time. We must choose one of the two. In non-functional requirements, the system can be eventual consistent.

The video is good, it is really good, but somewhere i feel the design is very synchronous that leads latency, like get booking for driver, that should be asynchronous with multiple listeners when the location of driver is changed , location service should cache and notify and put in booking pool

Thanks for that video, it was a good explanation. I just felt that the design missed a payment gateway service which is also an important aspect in the cab service, rest everything was perfect.

Hi which is best referral program software and coupon code software

Can we expect this type of design in a new grad system design interview ?

Good explanation.
Few doubts:
1) Can we employ clean up of NoSQL DB(old historical data) periodically to avoid overload ?
2.) Can you shed some light after booking a cab. Basically the journey till completion of trip.
Can we have a trip checker that keeps checking the distributed cache for the journey trial ?
3.) How rider can give rating for driver ? and how it is aggregated ?

When to use microservices and when to avoid it? Is there a pattern I can follow?

Hi Tech Granth,
In the video, you said we will keep the driver location in NoSQL DB, what would be the sharding key for cabs location data? To fetch fast their current location. The driver will be continuously moving after every 4-sec new location feed will come and the old location feed will be stale data.
Please help.

Superb

One thing can u clarify why u are implementing Kafka services here please eleborate I need more details

Hi - Location tracknig is needed for rider as well., a suggestion - so that the system can map the nearest available driver.

One more video request i have.
Design a shopping cart backend like of amazon scale.
Can you please make it ?

Can you make system design video on distributed logging system ?

Excellent tutorial 👍🏻 . Thanks for your efforts ☺️
