Thank you Yogita! Again another insightful video! I was thinking about the functional and non-functional requirements for a service like Youtube:
Functional Requirements:

-Watch a video
-Comment on a video
-Like the video
-Subscribe to channels
-Create Playlists
-Save video
-Post a video
-LiveStream options
-Display recommended videos or Trending videos

Non-functional requirements
-How many users to serve?
-How many people can participate in a LiveStream?
-How to handle multiple requests for most popular videos?
-Which technology to use to handle the requests or divert the request to server?
-Where and how to store the video data and in what format?
-How to extract the video data from the data store.
-Caching related to the most popular videos? Can be divided based upon country.

I was thinking GKCS was the best uptill now! But Yogita makes it very simple and easy to learn. I have been facing these questions from multiple companies but was not able to understand how to prepare for this. But yogita has one stop solution. Thanks a lot. And one request, please do a end to end interview process' video if possible. Thanks a ton, again!

[harisewak]

Excellent Yogita and Arpit! I hope you guys keep going :) I am an Android Engineer and using this course as a reference point to develop my understanding of System Design. Awaiting real world examples of capacity estimation!

[jerin]

Thank you for these amazing videos. Which online tools are popular to draw system design during interviews?

[Mohamed-ufjh]

Thanks, great job, to be continue ...

[abhisheknittala]

Exactly, this is the way to attack system design interviews.

[jayaramkollipara]

Can you make a video on all topics clubbed together. May be a standard system design interview question. I would like to know your thoughtprocess behind solving this.

[maidulislam]

This is funny, when you read SRS of Twitter like this
User should be able to post a tweet
User should be delete a tweet
etc.

[na]

What user can do that is functional and how it'll work is called non functional design

[RahulSharma-pmtt]

Good content! Just want to point out you don't need a job or have to work for some client to design a system, build your own product! Indians need to come out of job slavery mindset.
