Highly Scalable Backend with AWS + MongoDB [Architecture video]

[@renujadecosta6408]

Man I learn something new from this guy every single day.. Mehul you really motivate us as developers and also your channel is awesome for developers who have some sought of experience in web dev..You definitely are a PRO in this industry

[@unknown_manushya]

We want more such videos! Pretty much anyone who's into web dev knows Nodejs and all and there are plenty of tutorials on the same. As a backend dev, this is what is needed is lacking on youtube.

[@pranavbhat29]

Learnt the concept of how VPC works, and this is a piece of information which I can use for most of the system designs. Thank you so much for this. Had seen VPC everywhere but never understood why it is needed and how it solves.

[@cristianmontes3933]

I learned more here than I did when I was creating automation with Ansible and working with EC2, NATs, and S3

[@abdulraqeebm.3305]

I watched this video till the end. Greet content man, keep it up.

[@akgarg0472]

[@tanjillasarkartina7201]

Absolutely wonderful explanation

[@moona1993august]

I watched it till the end :D Actually i am a developer who is trying to deploy my very first full stack project. i dont have a team never deployed before. this is my freelance job. thank you so much for this video. helps alot

[@ToddHale]

Watched to the end. Thank you!

[@RonaldDas42]

Great! Had used the same AWS Lambda and MongoDB Atlas VPC Peering architecture to handle millions of daily SNS Triggers, works flawlessly!

[@mauriciotamez4047]

Amazing explanation Sir, thank you.

[@devchhaniyara3931]

I have watched this video till the end. Wow, this was super exciting stuff, really can't wait to finish learning NodeJS and move to Cloud Technologies, all this looks so complex yet exciting

[@pynick]

Watched it till the end nice content 👍🏻

[@sarthakduggal419]

You explain such complex topics with so much ease. It is just incredible. Big fan of your channel and your work !!

[@fist221]

Beautiful. Haven't seen such a beautiful explaination on backend arch ever.

[@himanshulal5135]

I watched till end . Thanks

[@thebackendcoder3147]

Your videos helped me got the job at R& D department of HP inc as senior software engineer. Thank u keep the great work

[@viallymboma9874]

I have not detected lack or uncertainty of knowledge in you before...you actually master the whole thing...not only programming by networking too 💥💥💯💯🔥🔥🔥

[@dijiflex]

This is some good explanation and i love it. Good work

[@ruhankhandakar]

always watched video till the end 🔥

[@prantachakraborty4002]

Thanks to you. Learning something new everyday.

[@anuragband8379]

Just Amazing 😍😍😍

[@PTM1008]

Adding a Lambda function to VPC adds latency to the function execution. Moreover, the Lambda functions can scale as per the load. Being stateless, every new execution/invocation will try to form a connection with the database. The database will choke in such a situation due to the lack of thread pool for db connections. Thoughts?

[@markbenson488]

I watched this video to the end, and I learned a lot!

[@vshlmlvliveit]

You make it super interesting 😎

[@chennalhere3210]

Just love it how you explained each and everything, would be amazing if you can create a video to cover how we can create vpc and nat gateway, Thanks 🙏🏼

[@gops6509]

This is 🤌 content!!!

[@manishrawat4161]

amazing video as always.

[@sasikalarao3476]

Awesome content , we want more of these types of videos ❤️

[@Archil1997]

Great content, thanks for sharing.

[@nithinbhandari3075]

Wow! Nice video.

[@souravdutta5703]

Please make more software system architecture videos 👍

[@yadneshkhode3091]

Thanks please create a whole playlist regarding architectures for eg event based architecture etc design principles etc basically everything related to system design you can even make a paid course afterwards regarding system design

[@raghupv30]

Video on connecting Mongo Atlas from eks cluster via private link would be nice to see.

[@toxolarant]

Thanks a lot 😍

[@emperoralthaf6264]

Hey hi mehul !, this is what I've been searching , wonderful content thank you so much!. I have some doubts.. could you please share some resources on how to use EC2 as a NAT gateway ? it would be very helpful. Thanks 😊in advance !!

[@prakashjayaswal]

great explain

[@HazemTamimi]

The irony thing is, today you just published that video, and today AWS is facing major outage impacting a lot of their customers 😂 Great video though 👏🏼

[@sandeepanumalla7785]

Please make a video on encryption algorithms in node js

[@asutoshpanda1508]

[@NeerajSingh-ch7wl]

in ur mongodb atlas dashboard peering VPC region us-east-1 some other place it is asia mumbai is it for any services availability problem or any cost base issue...

[@mhmmdshaz98]

I was doing your JS Challenges yesterday and it started showing connection problems when submitting the challenge. Also, yesterday there was news of AWS US-East going to sleep 😴 and seeing your MongoDB cluster sitting on the same region made me realise what was going on 😅.

[@moodyhamoudi]

Was hoping for more detail on how you solved the connection model issue for MongoDB atlas and lambdas - from my experience, using any TCP connection with lambdas (Vercel serverless functions in my case) is fundamentally incompatible. Using the standard MongoDB atlas connection model, you can only try to mitigate connection pool exhaustion by trying to cache the connection but you will eventually hit a wall. The only solution at scale with Atlas I found was using their new Data API, but that means all your MongoDB driver code has to be rewritten as HTTP requests since there's no support out of the box.

[@subhamjaguri9019]

it is great video, Thanks @mehul

[@olamilekanadeleke6806]

I watched till the end

[@suryapratimpaul]

I like to see a comparison video between Auto Scaling Group vs aws lambda.

[@aashishpaudyal5306]

why not use EC2 with ASG instead of lamda? It's it a cheaper option?

[@koby9340]

My dear friend Mehul could you please link us to some resources where we can learn the stuff you explained in the video

[@abhinavdubey4966]

[@rajathgatty]

Can anyone tell the estimated cost of this vpc backend architecture in aws

[@smaranh]

One question: Isn't the communication to VPC also a single point failure? Or is there some sort of a load balancer that handles this?

[@codedamn]

When you say VPC communication do you mean services communicating inside? Atlas, lambda and redis are all managed services by AWS so we wouldn't consider them as single point of failure

[@smaranh]

@@codedamn No, I meant the communication from the client to VPC. I was comparing it to the first point of failure you referred to in the beginning of the video, which I assume was between the client and the EC2 instance. You replaced this with client -> VPC but doesn't that still have the single point of failure? Or maybe I didn't understand the definition of single point of failure.

[@JeevanSunkersett]

I watched to the end. But why only Lambda. There are multiple ways to achieve redundancy and eliminate the single point of faiilure (that EC2), and then choose the best from the cost, performance, relaibility point of view.

[@rameezroot5225]

I watched this video till the end.Can we talk on discord?

[@nemotivity]

🔥

[@DebdutBiswasOnline]

Free version of MondoDB Atlas is denying any connections from EC2 instances.

[@yogeshjangra3603]

Watched till the end Can anyone help me to calcualte Monthly cost for below Architecture Mobile/Web User -> Amplify(React) -> API Gateway -> Lambda -> Mongo Atlas | | V Authentication : Cognito User Usage : 5-6 : Lambda ( getting data from multiple collections ) 10 : Users ( 500 req / day / user )

[@kumarvishalben]

or just use documentDB
