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.
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.

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.
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.
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 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
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!
Simple and detailed explanation :) I took multiple breaks in between the video to re-evaluate my understanding but your knowledge is really appreciable :)
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.
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.
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
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 🤪
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.
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.
00:00 Netflix's system design involves Open Connect and AWS cloud with three main components. 07:15 Netflix uses transcoding to optimize video for different devices and network speeds. 14:10 Advantages of using a gateway service and Hystrix for microservices 20:19 Netflix uses micro service architecture to power its API needs 26:09 Netflix uses caching layer and two types of databases for high throughput and low latency. 32:12 Netflix uses various technologies for data processing and analysis 38:29 Netflix uses personalization and recommendation algorithms to retain users. 44:46 Netflix's Open Connect server is designed for high availability and saves bandwidth. Crafted by Merlin AI.
Great video!!!..Good insights of the architecture. However this explains the actual architecture built by NETFLIX. A step by step approach of how the complex requirements are broken down to designing application by, may be selecting a suitable technology stack or algorithm that can be used is what actually expected in system design interview. That would help people for gaining insights in designing similar applications.
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.
Thx for sharing and in-depth analysis. One criticism though, I think at 10.51 it went little side ways. You talked about splitting the video to parallel process the upload but subsequent seconds it went straight to transcoded format. I do think 1. Split the video for concurrent upload & merge 2. S3 triggers transcoding
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?
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 ?
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 ?
Excellent way of explanation into step by step instead of showing all at a moment. Really useful to gain more knowledge base. Keep it up. Go ahead....!!
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.

Great work @Naren, Keep inspiring many more through these kind of real world theories !!
Wish you all the very best !!

Thank you once again for putting information from several different sources into one place.
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

He is Good😊
Great video man! by far one of the most thorough vid on system design! Really appreciate your effort on this
Quite enlightening with a lot of minute details for most of the components that fall under Netflix System, thanks a lot Narendra
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.
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.
Narendra, very thorough and great attention to detail in every aspect of design you explained. Kudos, great work!!
Wow this is an amazing comprehensive overview! Thanks for your effort
Thanks for sharing the video. It was very helpful.
Fantastic video explaining a streaming system design. Well done!
It would be nice to refresh this video in 2020. Thanks for great work!
best netflix architecture video ever. Great job Narendra!
Very thorough and insightful. Thank you for making this.
That was very interesting, excellent work. Thank you!
It's really detailed video with very nice explanations. Thank you.
A great explanation for such a complicated system
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
Thanks for this great video! very deep into certain topics... very different. than other design videos on youtube
Thank you for your tremendous effort. Detailed and well explained...
This is at Business Analyst and Architect level. Wow dude you absolutely nailed this.
This was awesome! Learned a lot
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.
very well structured video. very informative. thanks :)
Gratitude my brother! I'm so glad for your inspiration to teach me and others!
Thanks baby. I have been looking for system design interview questions. You made it simple.
baby :D ...

this is freaking awesome thanks for vid man!
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
24:05 i paused the video to see if dogs are barking in mt street !
8:50 also
Thank you so much for sharing your knowledge.
you did very hard work, man. Thanks a lot.

Feel free to go and have it done. And don't forget to shoot video afterwards.
unbelievably detailed. thank you
Thank you Naren! Great explanations!
Good one! Nicely explained.
very nicely described thank you!
Good job. Keep up the good work.
Another great session! Study vidoes like this and then practice at Meetapro with mock interviews will help you land multiple offers.
I appreciate your research. Keep it up
Very nice explanation. Thank you very much😀
Your content is really amazing. Keep it up! Maybe make a video on designing instagram next :)
@Ryan Bridges Thanks and sure
Superb explanation..
Gr8 efforts..
Thanks a lot
This was very interesting; I have learned a lot. Thank you sir.
very detailed explanation going component by component, however, I feel some of your delivery of sys design concepts still need polishing.
Very detailed and well explained
Thanks for the informative videos!! Question, do you do private consulting?
Great job! Thank you so much
This is a great video. Thank you!
ENJOYED it ,Well done
One of the best explanations I would say.

yes, but that would stretch the video by hours. may be I will plan to do smaller videos on different components. Thanks
Thanks for this video! so much of effort
Great video! Nicely explained
Thank you so much for your work, amazing job 🙏💪😌
You are amazing ! Thanks a ton ! cheers :)
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
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.
Thanks for good info.Please could you provide more details if request flows from UI to back end,that will give more clarity
Thanks , this was really helpful
Very good explanation, thank you sir.

How about adding capacity planning? Session was wonderful and informative
Very useful Narendra. Thank you so much!

Great video. Can you do a video that looks at payments and what the architecture looks like?
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 ?
How can the 2 screens or 4 screens strategy of netflix be implemented?
Good question..
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 ?
Great explanation. learned a lot. 👏👏
Hi! Thanks for you tutorials, please you can make a tutorial of Alibaba or Aliexpress system design?
How about security? How does Netflix makes sure only authorized users can view the content?
Yeah seriously, the best explanation!.
you are unmatchable !!
Just another kudos for interesting video. What do you thinks about their use of Cassandra? Why it but not just another instance of ElasticSearch?
Excellent way of explanation into step by step instead of showing all at a moment. Really useful to gain more knowledge base. Keep it up. Go ahead....!!
Great Videos Sir .
This was excellent !
