I am a Data Scientist but I still watch and try to code along with all his tutorials to just learn dev stuff and I must say I have learnt a lot from you Harkirat, Great video and things are way more simpler and easier to understand if you know basic stuffs ..
Hi Gyan Prakash, can you give me a referral for any data science role. I am new into data science with 1+ year of experience. Currently working in TCS.

This content is like most fine thing u can ever get on UA-cam just love it pure educational video , tremendous learning , straight to the point teaching hope to I could also give back to dev community after some years just like harkirat is doing for all of us
wait, this turned out to be more straightforward than I expected. Thanks for making us thorough with the process!
So much condensed contextual knowledge and you explain terminology explicitly so it is so easy to understand.
Very well organized content as well, and you're using a use case as a story the entire time, so it's very easy to follow.
Learnt a lot and recapped a lot, also enhanced my existing knowledge about deployment through your terminology and good practice explanations.
Love it!
Insane tutorial. I have watched only few minutes yet but the topics you are trying to cover here are advanced tier. I can't believe this is all free. I also tried to make a simple deployment system for plain html css js and this is just 10x more advanced than it
voh paid kardega , tu jayda bolega toh

@@eren-qu9uu😂😂 Are bro, I guess wo paid nhi krenge, because jb unhone kuch courses paid kiya to log telegram se free me access kr hi lete h usse better h directly free me access krle
Can I use Microsoft Azure instead of AWS
You are not the every day creator on UA-cam you are the real deal and one of the best teachers out there unlike other on UA-cam who just sells courses and output low quality content ❤
this is an excellent tutorial from a systems design perspective. the key value proposition isn't just serving static assets via http but the proxied endpoints mapped to backend process (serverless, server process etc) http routes. so in the end I would say we're halfway there, what's beautiful about your solution is that for the most part the services in your architecture don't change. i also love that you added citations to vercel's archtectural blog post. wonderfully explained, thank you so much, you're a great teacher
Hey @harkirat Singh, I am in the last part[frontend] of this video.........Your video is incredibly informative! . Your clear and concise explanations make your videos stand out, majorly, I love how you break down complex topics into digestible chunks(most of this i had seen from cohort[Top-Notch]). Hats off Ser!!!!
Bro just asked before start ,any paid thing use in video ?
This is insane content man. Please keep uploading such videos where we can learn high level stuff while building real world projects. Thank you harkirat.
Love the system Design instruction at the beginning, Please make more interesting projects! Great job on demystifying apps we all use. Would love to see you break down more complicated apps and simplify them like this!
one of the best tutorials for me, thanks for it. I like that you introduced the architecture and showed what the process looks like.
I am in between of video but paused just to comment.
I am having 3 years of development experience and wanted to start a startup. But things were messed up how things will be done in backend.
I think the concepts in this video will help me a lot. I will be updating this comment if i got success in making my startup. Thank you Harkirat
you kill it man we are good to go with this pace , next tutorial on webrtc or , or something real-time protocol ❣❣❣
Let's make this comment Lil popular so that harkirat can read it
bhai jab bhi teri video ya live stream dekhta hu mujhe lagta hai ki mujhe to kuch nhi aata, you are a role model
A great video, i was engaged by the beautiful content throughout the video and also tried to code along. Thanks!
Harkirat you are doing Awesome brother. I appreciate your all works and your efforts for our community. Stay long front of us bro. 😎
amazing video. loved it throughout. perfect pace.
Great job explaining these concepts. 🎉
harkirat bhaiya you stands out with a true commitment to empowering and educating. Their belief in the importance of sharing knowledge freely and making learning accessible to as many people as possible is both refreshing and commendable. Your support not only motivates but also ensures that the content delivered adds genuine value to our learning experiences. Here's to a creator who prioritizes education over profit, making a positive impact in the learning community!
Keep bringing such tutorials, its Really helpful!!
Bro that's a sick project idea. Genuinely impressive.
Getting this quality of Free resource is just mindblowing..Thank you so much for this awesome effort. hats-off ❤. keep doin this stuff for us :)
VERY NICE PROJECT . I WILL TRY TO UNDERSTAND COMPLETELY
Absolutely insane to get this level of content on youtube. I've been on here for years looking at different devs. This year alone I've found two incredible - you are one of them. This is a super crash course for devs. Thank you so much. Top quality
who's the other one though?

Salute to you man 🫡🫡🫡🫡🫡🫡
Please please keep uploading such high level content.
Wow, amazing tutorial just the way I wanted. Please record more code alongs like this. Thank you :)
Amazing video. I like it because it didn't took much of time as pace was very nice, Thank You
Thank you for providing great content
We need more of thisss!! (Thanks alot!)
amazing explaination and video editting!... this is best reply of controversy!!!!!!!!!!
Very valuable video as all are. Thank you so much.
I'm watching Harkirat in videos from his IIT-Roorkee days where he made a music video (Sorry - Justin Bieber) 8 years ago. Kudos .He is doing great & I have seen every bit of his growth
CHEEZ-UZ! What an Incredible Project! First time on your channel and I have subbed!
Interestingly my approach was very similar to yours. This video really boosted my confidence about my way of thinking to make a system!
that short intro and history at beginning was great.
Great video! Interesting stuff that you're very adept at explaining.
It’s great to get a sense of how a platform like that works with such a straightforward explanation! Wish you had gone through the containerizing part though. Is that something you think you might eventually put into a video? Maybe kind of like a sequel to this one 😂
High quality video, we want videos like this
Thanks Harkirat you gave me an overall idea how to make UA-cam video uploader which you discussed in one of your project ideas video will start working on from today only Thanks again
just complete in 2 session, i didn't code along . But i did understood all of the things. Thanks sir.
The video is amazing! And you do know your stuff! One thing I find weird is how you're trying to build something which can be quite complex in terms of architecture but also you're explaining basic stuff like shell commands and what API handlers are. I can't really get which audience you're trying to target. Keep it up!
During explaining, the words "K Bhai" gives a smile. A very informative material you are sharing with us. ❤❤❤
Few days back I was thinking how do I build vercel like service? Now you are here. Thanks a lot.
Please build a Resend like service.
kaffi age ki sochte ho
Yaa this is I am looking for, make this type of content, it's very help full for a developer really appreciate, in UA-cam there are few content like that....
Thanks Brother ! It's just my starting on building projects. Sometimes it happens that i am not getting sequence of project in my mind but Now i can atleast try to make different projects in these type of domain....
You are a gem harkirat..
harkimouse
Hi Harkirat, I've done a number of projects from YT, and I've always been searching for a solid backend one that wasn't trivial - this is the very first one that fit the bill and the best bit is you explain incredibly well! Just one thing though, any chance you could add in the bit of how to add the 3 services to the EC2 instance? That would be incredibly helpful and help us to add to our portfolio. Thanks again.
It feels unfair that this man have a paid bootcamp but is still uploading high quality content like this on youtube. Salute man. I would also become a kick-ass dev like you soon.

@@nikhilnair1393 lmao
These videos are like gold mine, people only love hype videos
bro started at 3 in night and finished around 11 in noon. That's great dedication, hats off.
Bro, this video is awesome. I want more
This is masterpiece. This man is legend
Just learned Python Basics & watched your video. I could able to understand how an entire application can be developed.
Awesome this is a real world project unlike a TODO APP or ECOMMERCE website
but that's essential too
Those two applications are the most important applications
Actually these small projects are necessary to build that's what i feel , As these small project gives better clarity of concepts to a beginners like me
@@lightyagami-jj4ve Ecommerce is small project?? 🙂
exactly you can do a lot more with an e-commerce project aswell@@vrohan07
Amazing job ser, good speed.
For the getAllFiles function at 49:48, instead of using the sync filesystem functions, you can use the built in node util promisify function to use the non-blocking (i.e. non-sync) filesystem functions. This is a huge benefit because sync functions will block the main thread, preventing any concurrent requests from being processed. A web server that receives many requests will be hindered by the use of sync functions.
Loving the videos ❤🎉
Respect for this tutorial
We want more videos like this 🎯🙏🏻
Wow, u r a great motivator, learn, code, share.
this is content, for which i pay my network bills
Awesome project bro
Very detailed explanation as a dev. It was fun to watch. Although i am not at the level of system desgin as your sir.
I'm waiting for a Vercel-like open-source service to emerge. 😅
Keep going, teacher!
Best tutorial ❤
Yes! Quality content.
GOOD quality tutorial.
It was neither slow nor fast.
if you have time please do the hosting, it would be cool .
Thank you for this video.
Priceless content Harkirat bhai, please dont stop this high quality.
Actually, this is a part of the cohort
Interesting video keeping making similar kind of videos more
On the upload service:
1. Seems more straightfoward to do a fast zip compress of the downloaded repo so listing all files recursively isn't needed. That would make the upload step much faster.
2. Highlighting a limitation for folks following along that is worth calling out in an interview - deeper integration between git remote and local copy would be good here. Specifically, add a cache of git project URL -> id-based folder name, and track the remote branch in the cloned repo folder. This will unlock incremental downloads on subsequent triggers of the same URL. Incurs storage cost, so use an LRU cache and tune TTL as needed to purge stale repos and only maintain hot repos.
3. ID generation best practice is to use base58. This guarantees a unique 21- or 22-character ID that scales well and transmits well over the wire.
This quality I need
Hi harkirat the video was fantastic. But i have a question that you are using async await in forEach loop and forEach itself does not directly support async/await because it does not wait for promises to resolve. to overcome this you can for..of loop or map and then use promise.all(). Please correct me if i'm wrong over.
Have always loved to create real life complex tutorials developing seemingly complex systems like this thanks for the motivation.
Actually written a cloud platform similar to gcp using next express and front end with next js tailwind shadcn and I was really happy on what I achieved with scalability using dockers on say your raspberry pi and users uses containers to deploy there systems. Definitely deleting it and writing it again from scratch and uploading to UA-cam.
Bro amazing khatarnak project thankyou sir g
Great tutorial. thanks
Super impressive can't believe we are getting this for free😮
Loved the video please make a similar video about nextjs .
Dude kudos to what you are doing
Just a question: can you give a glimpse of how would their Vercel Edge Functions work?
i love these videos thank you. Redis always been so confusing to me lol i feel dumb.
You are the best brother.
Hi great tutorial. One suggestion instead of uploading and donwload files individually u can zip, tar compress them and upload them this way u dont need
1. The resirsive logic
2. The network usage is less.
How are you even able to put out such.a info rich video along with you working full time and also running a cohort? How are you at the optimum level?
Hi Harkirat, thanks for the video. I missed the point, why we need to upload/download src code to/from S3? Why we can't just get it from the repo, build and upload the compiled one to S3 in one step?
You can use traditional for loop instead of forEach at 2:30:27
For loop and for await are the only loop in nodejs that waits for the complete traversal.
Thank you sir 🌝
Awesome 💯
Whether the code uploaded from github contain both frontend and backend code and how the system handle deployment need of backend......?
you aren't regular uploader on youtube but if you upload it will be a big bomb !!!!! :). By the way are you only backend developer in your company where you are working?
More code along videos please
Crazy stuff!
50:46 for anyone wondering, with node v20.1+, something like:
const filelist = await fs.readdir(dir, { recursive: true });
is possible
I wish I had seen your video when I started learning how to code.
just harkirat being harkirat
Why don't you compress the files to a tar or zip and then upload them on S3 at 50:00
It would reduce the logic on the deploy service too. We can just download the zip file and decompress it locally
This is actually a good idea. But then it would require you to download them on the other service & have logic to go over the extracted stuff. Wouldn't it end up being the "same" thing?
@@VitorSantos-bh1mk No, we already have several libraries to convert a folder in to zip. Also, by uploading zip we've to worry about the only zip file that we have uploaded. If it's crash by any reason while uploading we'll be notified but uploading a complete folder with nested files would be hard to identify the crash files.
Thank you very much
@44:48 instead of gettng all the paths, why did you not compress the dir into a single file and upload the compressed file?
Bhai pura hero lg rha haii... 😀😀
bhai tu genius hai
Hi harkirat sir can u explain the issue u we're facing at 2:29:03 since u have promisified the upload file function then why this issue is coming
Hey, great video! I noticed at 20 minutes in you have SNS queue, should that be SQS?
