FreeCodeCamp is amazing! Only yesterday, I was learning Assembly Programming with ARM for beginners on this channel, and today there's a system design course already waiting for me! Thank you Gaurav for creating such a thorough resource for free and FreeCodeCamp for bringing it to millions of learners like me :)
I am not even a software engineer but the way he started explaining things make so much sense to me and made me stick to the video till the very end. Gaurav knows who make it engaging. Kudos to FCC and Gaurav!!
That is what system design is all about. It's meant to be understood by the layman. Surprisingly the most important part of programming is not in writing the code rather it's solving a problem using logical sequence that captures everything problem solution(system design). If you are not good at this then programming may not be for you!
sorry for the late reply but learn system design at the start may be interesting for starting but you need to learn how to write code and make good projects.@@illuminatidaylight8566
Thanks Gaurav, Glad to have you here. I worked on many case studies of your classes and has tremendously helped in getting my system design skill to an advance user over the last few months.
"The next step is to convert these requirements into classes and objects. This is where things usually go wrong." exactly what brought me to this video
For me, it is not about SQL or noSQL It is more about: - Is it cheap? is it scaleable? at this stage of the project can I utilize my available resource? - Do we need schemaless/no schemaless, usually because of shameless, the database needs to take more space for storing and is slower at execution. Like dynamic-typed langue vs typed language. - Can I make relationship ? (typically the NoSQL is considered weak relationship, BUT YOU CAN STILL MAKE RELATIONSHIP. PLUS, BECAUSE OF SCHEMALESS YOU CAN EMBED DOCUMENT FOR MAKING THE RELATIONSHIP AND MAKING THE QUERY FASTER WITHOUT JOINING ACROSS TABLES ) - How about its built-in function? it is usually better if you make the computation on the database instead of pulling it down to the server and computing and of course, you don't have to re-develop that function - The last one, of course, which type of database is more familiar to my team
In terms of databases you really only have a few types, NoSQL, SQL, and in-memory. The brand of the db is almost irrelevant any decent engineer should know how to work with any of them.
Please, do something about architectures like layered, event-driven, etc. To a newbie like me it’s really complicated to build highly responsive projects.
I really liked this course. it includes not just the patterns, but also connects it to the process of distilling Business Needs as an engineer. Thank you for sharing this course! Excellent point about testing the design, especially for large complex systems.
Teaching something simple thing in complex way dose not really mean learning system design, rather knowing philosophy behind a system or process is more important.
Great video. 1:18:43 - if going with variable frame length, then, if a frame is extended with absolute start position attribute, it becomes possible to do binary search within frames array for timestamp, instead of linear iterations ( O(log n) vs O(n) ). With fixed frame length even better, instead of iterations just divide timestamp by frame length, and we have a frame index in O(1).
Wonderful, I am just a passionate newbie who jumped in the field of programming a while ago I learned the languages and the tools now, I had to make my final project which is going to be a full stack project, but I was really confused that how you can create a well-functioning Application and thanks to Gaurav Son that I got to see the clear path of creating an application .... ( :
You talked a little fast, but wow, you sure a happy happy person dispensing your knowledge and I for one grateful. I'm taking an AWS Machine Learning course and getting to seee some nuts and bolts was absolutely great. That was a lot of work and you know it like the back of your hand. You you don't have a company yet? I have OPENAI ChatGPT, and you remind of the guy the Sam Altman, knows everything about how it works. really good job. Thank you.
Yeah I totally could have used this video last year when I was deep into my capstone project, except I was trying to figure out all this stuff with my team trying to come up with a very similar program, our conversations were very similar to everything in this video… we weren’t able actually make a viable product tho, this would have been a great help… we were missing some of the late video processing parts that were very complex to get implemented and working
thanks for this video! I am a PM and would like to understand how developers work. Would you have a recommendation on the time taken for each stage: api design, database design, protocol before implementation?
For "Go back to video and watch from timestamp", couldn't it be `play(user, videoID, 0)` where if it is 0, you check your cache to see if the user saw it previously? I also think that watched video shouldn't be a separate object because it doesn't make sense to create a new object every time a user watches a video. Instead, I think there should be a database table for watched videos with userID, seekTime, and videoID that can be queried in the VideoConsumingService.
Thankyou so Much , This is a very informative video , this videos takes us on a journey where we think deeply which we never thought before , How in detail a engineer thinks about every aspect from making a call for next 10 seconds video frame , and all the various parts to make sure for a user the complete experience is so smooth and he never bother about it ... Thankyou so Much it is a great video to start learning about system design , It is interesting and Informative 🔥🔥
It's a pity that nobody helped the instructor get set up with proper audio. Long courses & videos are fatiguing to listen to when audio quality is poor. This matters to the mission of freeCodeCamp. Proper mic'ing is easily within reach economically these days, and audio engineering, acoustics, and home audio recording technology are not particularly complex topics for those with a STEM degree who've had the standard classical physics series.
If a course starts with "hellou ewerywone!" I at least know that he put in the effort and worked damn hard to make it! Cheers! (For the trolls, this is not racist but actually respecting and valuing the creator and effort! I have been to India.) Thanks Gaurav, great intro! 🤘🏻😎
I am still going through the video, but just wanted to say thanks so much for making content like this. It's so well thought out and articulated. I am a mid-level engineer and I have a rough, abstract understanding of most of these concepts but I need the nitty gritty to be reinforced so that I can talk about it confidently. You covered exactly that in your example. Thanks Gaurav and thanks freecodecamp for another video that hits the nail on the head
1:18:47.. isnt the timestamp condition inverted? Shouldn't it be if (frames[i].timestamp >= timestamp && frames[i].timestamp + Frame.frameTime < timestamp)? Great tutorial btw
What are the pre-requisite to study this? I'm in my freshman year of college, and we don't have any computer science subjects in the first two semesters
You can watch this anytime you want, but recommend having some knowledge about full stack development (or backend development at least)before watching this, so that you can understand more effectively like that is an API and Epoint, etc, etc.
Ii dont think the course is made for Beginners. Ive been working as a mobile app developer for 4 years now but I dont know all these protocols you are talking about as well as db architectures. I think we need more explanation on what are the options to choose from and why you ve chosen a particular solution Overall thank you for the course and your precious time.
isn't bad design to define a videoframe api depending on client state? "give next 10 seconds" is not a stateless REST API. It can increase scalability complexity.
Free code camp can do better. This one particular example was relatively clear at times but the underlying principles of system design and considerations of how to approach a problem rather than solve this problem in particular weren't really approached
i have 3 questions! 1. when commenting on a video.. why is the author's name sent in the POST, if the system already has it? (by processing the token on the header of the POST request) 2. why does the user (after closing the window) ask for the timestamp, and then make another request with that value? the way i see it the server already has that data too.. it could directly return the videoframe on the 1st request 3. and the last one... how is it possible that when commenting, the ID of the comment is sent in the POST? thats the most weird of all.. it is not even saved in the database yet. it doesn't have an ID. or even worse.. would't this lead to duplicate IDs if 2 users comment at the same time? am i sharper than normal today, or am i missing something? excellent video! learnt a lot from it , thank you very much 🙏
thanks, great video, probably coding is not a part of a system design and not sure about spending that much time on the specific use cases, because I'm guessing each use case could be a separate system or described as a separate system design
Just to let others know, Gaurav has started his own startup and is being helped by the startup cell of Maharashtra state to smoothen out the process.

A large scale system design for beginners with no experience!!
And they will hire you as a Senior System Analyst too.
Good luck in your career!

Prerequisites for understanding the concepts is some sort of APIs Knowledgs, Networking Protocol, Database System. Just need basic concepsts.
Thank you, the one and only Gaurav Sen!!!

Thank you!
Please, do something about architectures like layered, event-driven, etc. To a newbie like me it’s really complicated to build highly responsive projects.
I have a video on event driven architectures on my channel.

I agree to this
I know all this but I was doubting my self that, Is my way of system design is right. Now I am more confident thanks 🙂
Most precious gift for the web developers!

I typed it on the search box, and you have uploaded it 5 hrs ago, Delightful!
Nice short introduction to system design! Nice job Gaurav!
Requirements (most important first) , then think of the object for feature, endpoints,outage proofing, extensibility (easy to change) , test
One of the best videos i have where it explains all nuances of system design from front end to back end, how APIs work, DB, network, protocols etc. 👏👍
I want to get placed as a software Engineer so do I have to learn system design ?
Should I watch this course ?
@@illuminatidaylight8566This course is not sufficient. Yes,you need to study.

Who knew the power of free knowledge ! Thanks man for all the effort.
"You want your features to be extensible. For this, you have to take out your engineering crystal ball, and gaze deeply into it..." 😂🤣
best gaurav sen system design video ever
Excellent walkthrough! Nitpicking: at 33:37 RTMP must be arrow-connected to the "video" table, not to the "user".
You posted this at the perfect time thank you
For Real!! I didn't notice it was posted 7 hours ago but it is such perfect timing for me
He is Gaurav. The God Of System Design.

Salam from Lahore, Pakistan
thanks for this video! I am a PM and would like to understand how developers work. Would you have a recommendation on the time taken for each stage: api design, database design, protocol before implementation?
Wow just what I was looking for this year!!
This channel never fails to provide free knowledge
Thanks for this course. It will help to design my project better.
This course is decent!
I learned this course in my degree, and it cost 3500 USD.
Huges thanks to Gaurav Sen and freeCodeCamp.
Already learnt form this legend
Nice Microservices reference! 😂
Just started the video, so far so good, should be the first step when thinking of creating software
thank you for this. System design is on interviews and there are very few resources.
You can also try InterviewReady for system design interviews.
For "Go back to video and watch from timestamp", couldn't it be `play(user, videoID, 0)` where if it is 0, you check your cache to see if the user saw it previously?
I also think that watched video shouldn't be a separate object because it doesn't make sense to create a new object every time a user watches a video. Instead, I think there should be a database table for watched videos with userID, seekTime, and videoID that can be queried in the VideoConsumingService.
This is wonderful. Much love from Nigeria
Oscar award for Best system designer.
The knowledge and versatility of Gaurav is just amazing, I m stunn
A fantastic resource for any newer software engineers.
Great Tutorial, videos like these really make a difference. Thank you for the efforts Gaurav and the team at FCC.
Wowow! Super informative! Better than I had in my school!
Excellent course, thank you! I really wish though that the audio quality was better
Really I wait for that course so long
Try reading books. 😂
I think overall the content was great. But I am not sure if example of video processing and serving was well suited for beginners.

Pretty well summed up by him , helpful for beginners like me
Liked it. Very informative in an easy-to-understand way!
Why it will be different coding in Python? Python also supports OOP.
