I must say, this is one of the best ASG's set up tutorial out here.

[albertndege]

This has to be the best AWS tutorial ever come across, Thanks @Raul

[rajendrawarrier]

Crisp and clear explanation in layman's term

[kokopopart]

Very well explained Rahul. The graphical representation really helps put things into perspective.

[kaycay]

your videos are very detailed which help us to get complete knowledge in single video. thanks for your contribution... i have only 1 question in asg that how this instances in asg are also in target group. we have left the target group to be zero since asg will create ec2 instances based on min/max/desired how these instances will be added in target group ? that is my question

[shivadheeravath-sopu]

Excellent Content Dear Rahul, Thank You So much ..

[milon]

🎉 would you create a video on

deploy a small to medium scale node js api on aws for small startup with minimum cost like 25-30 usd per month.


which could increase in future.
also maybe not use load balancer to reduce cost. and use docker container. and auto scaling etc

[rajbas]

very good explanation Rahul ...thanks 👌

[johncaipa]

Hi thanks for the video, I wonder if the instances share the same volume or each one is independent, I also wonder what the estimated monthly price is for this setup

[subhashismohanty]

I wish, I could give a medal. Kudos to you brother.

But one question, in the ALB security group, are you sure we should allow outgoing requests to all IPs in the outbound rule?

[ahmedsalahel-din]

Thank you a lot for the video👍

I was expecting to use the auto-scaling policy for any metrics, e.g. CPU util. or load balancer request count

[rocktech]

Thanks for this wonderful video.
I have few doubts, can you help.
I built restapis using Node.js and express and deployed them on to the ec2 instance and using nginx as reverse proxy and load balancer.
I built these APIs for our startup.
I'm using t2.micro and my APIs are using in both android and IOS apps.
I also implemented ci using GitHub actions and running cicd pipeline, it's working fine.
Now we have app launch we have app launch we are expecting 200 user and they all gonna use at a time.
so do i need to implement these autoscaling or my nginx loadbalancer can handle it or not.
and also after these detailed information can you explain me what else i can do .
if i implement this autoscaling group can i use my running instance and if load increases i will add one more instance.

Thank you

[sanasaryuzbashyan]

Rahul thank you for such a wonderful explanation. I just don't understand one thing. When the third instance is launched automatically, how will my project's code be deployed there?. Actually, I'm not sure if there is a smart way to deploy my website's code on all these instances, or is there another way to do this?

[giteshghure]

Thank you very much Sir for this all AWS Course

After doing the exact configuration, I'm getting "502 bad Gateway" I do not understand why.
