this seems like a video on "how Netflix works now", instead of designing a Netflix by yourself. will be more fun if you can start with something simple and then try to scale.
Agreed, it's better to underrated thought process behind each decision. Anyway, as always, amazing video.
appreciate the content, but imp part of system design is why you have to do it the way you did it and why something else wouldn't work.
That's what the title says :) There could be another video that can come up with the basic design and build upon it. The intent of the video itself is to showcase Netflix design. I myself want to know how Netflix works.

Thank you for this wonderful video. I work for an SVOD company and found this very informative and it even helped me understand our own system better!
Your depth in videos and breadth of content is absolutely amazing. Thanks! I really appreciate how clearly you explain things and make complicated systems look quite simple and logical. Please continue with this "starting from basics" approach, it's honestly one of the best on YT.
Also, do you have any good book recommendations for ramping up on system design? Like some book that points out a problem and gives a system design pattern to solve it? If there was like a "Elements of System Design" or something that'd be great.
Great work @Naren, Keep inspiring many more through these kind of real world theories !!
Wish you all the very best !!
Extensive research performed for this presentation. Pros & Cons, IFs and BUTs of most of the component of Sys Diag explained. He gives different options before selecting a solution. One needs to connect the dot and understand the bigger picture of how it's scaled. Thank you.
I went through only little part of netflix architecture through their engineering blog before. But thanks to you, now I have full overview of their systems. Also, please make video on Food Delivery app.
Thank you once again for putting information from several different sources into one place.
You have done fabulous job of describing the components of Netflix. It's comprehensive and your efforts are very visible, thank you so much for going the extra mile for others. I hope life rewards you for this!
He is Good😊
Really detailed video for each component. Keep up the good work.
Thanks for sharing this video. These video might touch many of the lives to get into there dream jobs
Nice video with almost all details. Great work!
Excellent.I really appreciate such a great work.It helped me a lot to understand how the system works. Expecting more videos.
Thanks for sharing the video. It was very helpful.
I think this is great. Loved it in the way you have componentized the entire architecture. Really helped me a lot to understand it. Also useful would be to focus a bit more on the different data models in the database. For example just on a high level how data is stored. I would not expect an in depth schema but something on the high level. Also useful would be to include the approximate bandwidth required for such a system. But in all this is great and I really liked it
He Is Great I love the way he address
Simple and detailed explanation :) I took multiple breaks in between the video to re-evaluate my understanding but your knowledge is really appreciable :)
I think most of the guys take multiple break. Even i took many.
Wow this is an amazing comprehensive overview! Thanks for your effort
Narendra, very thorough and great attention to detail in every aspect of design you explained. Kudos, great work!!
Quite enlightening with a lot of minute details for most of the components that fall under Netflix System, thanks a lot Narendra
Great video man! by far one of the most thorough vid on system design! Really appreciate your effort on this
Thank you, this helped me alot
This was awesome! Learned a lot
Very thorough and insightful. Thank you for making this.
Fantastic video explaining a streaming system design. Well done!
It would be nice to refresh this video in 2020. Thanks for great work!
It's really detailed video with very nice explanations. Thank you.
That was very interesting, excellent work. Thank you!
A great explanation for such a complicated system
24:05 i paused the video to see if dogs are barking in mt street !
8:50 also
very well structured video. very informative. thanks :)
Thank you for your tremendous effort. Detailed and well explained...
best netflix architecture video ever. Great job Narendra!
This is at Business Analyst and Architect level. Wow dude you absolutely nailed this.
Really appereciable.You are doing good for people.Thanks a lot for your efforts.
Very nice. Thanks for explaining module wise. This brings clarity.
Thank You, it is a very good video on streaming platform and covered many use cases.
One of the best explanations I would say.
Thanks for this great video! very deep into certain topics... very different. than other design videos on youtube
Dude you are a legend...
Thanks for the epic videos!
Thank you so much for sharing your knowledge.
unbelievably detailed. thank you
great work! excellent collection of videos. extremely informative
Gratitude my brother! I'm so glad for your inspiration to teach me and others!
bro awesome work done, thanks for that. keep up your good work going.. god bless you
this is freaking awesome thanks for vid man!
Thanks baby. I have been looking for system design interview questions. You made it simple.
baby :D ...
@@raviprakashagrawal9478 host -> #floored :D
lmao.
Narendra sir #sakhti pighalna nahi hai
very nicely described thank you!
Thank you Naren! Great explanations!
This is amazing! I didn't like certain parts but overall this is a fantastic video. Clearly shows how much effort in research, articulation, rehearsala, etc. must have gone in preparing this video.
He Is A Genius
It was the perfect video for me. I needed some information source that was suitable for the report I have to write for the University
you did very hard work, man. Thanks a lot.
Really appreciate the video. Nicely explained.
Good one! Nicely explained.
Very nice explanation. Thank you very much😀
Thanks for the informative videos!! Question, do you do private consulting?
Nice one in the era of 'system design interview preparation' videos, where, they explain cache is to save a DB call and cache can save DB call and further explain that you can save a DB call by reading from Cache and go really deep, cache can save time by providing response quicker 🤪
Good job. Keep up the good work.
I appreciate your research. Keep it up
Great job! Thank you so much
This is a great video. Thank you!
Nice video. But i would have expected a simple and scalable custom design, that can help us understand how we can tackle/handle this thing on our own instead of knowing how they actually do it.Please do one video on designing netflix basic design from scratch. Thank you.
Very detailed and well explained
Thank you so much for your work, amazing job 🙏💪😌
Superb explanation..
Gr8 efforts..
Thanks a lot
ENJOYED it ,Well done
Great work. Thank you, please, continue with it.
You are amazing ! Thanks a ton ! cheers :)
Thanks , this was really helpful
These are all great videos. Thanks for sharing. BTW, is this design - how you think should be ? or how it is actually ?
I asked the same question... I think he is just speculating. This is proprietary information.
Very important to learn how to think through while building such systems..... that's where we pass on the actual knowledge so that ppl can learn the thought process rather than memorizing their implementation. Please focus on such a style of presenting these systems.
Great video! Nicely explained
In addition to that Netflix uses HLS which is a technique of adaptive streaming a m3u8 file decides which chunk to send next according to bandwidth of internet the video you watch is not a mp4 its actually a .ts chunk which the player display you hence its a technique to secure the video too
This was very interesting; I have learned a lot. Thank you sir.
Very good explanation, thank you sir.
I have a question :
1. What is the flow to capture "last timestamp of content viewed" ? What could be the service level API calls and DB backing this feature.
Thanks , highly effective space for learning System design
great video. I have one question. does AWS have global load balancer? if not, can you tell us what kind of load balancer they have created .. do they create one in every region? Also, from mysql database point of view and EC2 clusters, how do they handle global replication of data?
Great explanation. learned a lot. 👏👏
Nice video.. One thing I am still confused. If a new video is uploaded to Netflix , then it would chunk and process it to save it in almost 1200 files. Now , where are these files stored ? In Cassandra ? Also, do these files existing in EV Cache ( LRU eviction policy ) ?
Can we put these files in CDN as well for quicker access ?
Another great session! Study vidoes like this and then practice at Meetapro with mock interviews will help you land multiple offers.
Very good explanation of each component. Thanks a lot. However, I would highly recommend after all the individual components explanation the end-to-end flow in the architecture diagram on the home page request of what happens and click on the movie to watch how the request flows what components are involved.
It's like a summary of the total design in 1 or 2 minutes. Keep up the good work.
Feel free to go and have it done. And don't forget to shoot video afterwards.
Very useful Narendra. Thank you so much!
this is very good system design topic and i have one simple question, why are we saving the data on Amazon S3 and then transferred to Open Connect servers ? i mean after conversion of the content can we directly store on the OC ?
Your content is really amazing. Keep it up! Maybe make a video on designing instagram next :)
@Ryan Bridges Thanks and sure
Very interesting. Thank you very much.
Yeah seriously, the best explanation!.
Great explanation dear ....Thanks
How can the 2 screens or 4 screens strategy of netflix be implemented?
Good question..
thanks for the video!
Thank you for ur great work! We thank you a lot!
Thanks for kind words!! :)
@@TechDummiesNarendraL of course we should thank you, we didn't pay anything and we learn a lot from you. There has no reason to complain 😊
you are unmatchable !!
Great Videos Sir .
How about adding capacity planning? Session was wonderful and informative
Just another kudos for interesting video. What do you thinks about their use of Cassandra? Why it but not just another instance of ElasticSearch?
This was excellent !
very detailed explanation going component by component, however, I feel some of your delivery of sys design concepts still need polishing.
Very well explained👍
Thanks for good info.Please could you provide more details if request flows from UI to back end,that will give more clarity
Im Really very confused. When you defined open connect . I was honestly expecting you to use the AWS managed CDN network CloudFront. As they both use edge locations and Which has streaming possibility, if you use Elastic Transcoder to turn high quality Videos to HLS (HTTP Live Streaming) format and a CloudFront Distribution with a download option to Stream it from S3 its a better option. Or so I thought? I have an interview at amazon coming soon if you could answer this I would really appreciate it!
Yes that would be an acceptable way to transcode and stream content. However he is defining how Netflix does it which is using their own CDN system.
I think probably already invested into open connect, so after moving to AWS didn't want just to throw them to trash but reuse it.
Amazon Prime uses CloudFront, NetFlix use a propriertory CDN
Great video. Can you do a video that looks at payments and what the architecture looks like?
THANK YOU, RESPECT
