🎉 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
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?
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
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
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?
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
Not working. Health check grace period = 20. It is impossible to create a new instance and do health check in 20 s. This leads to loop like creating and terminating instances leads to server error 5xx. After changing it to 300 everything is cool. Sometimes legend make mistakes. Expecting reply from Rahul Wagh for this one
@rahul thank you for sharing knowledge, I tried this same to same setup but my instances are not getting public IPs and hence none of the instances gets healthy in Target Group. please advice If I am missing anything.
Load balancer will not scale up or scale down instances but instead it will just distribute the traffic equally but autoscalling will increase and decrease the instances
Hi Manoj i have stated terraform series to provision all the things which i have shown in this tutorial but it only for the youtube members. If you are interested then you can join my membership program. Here is the playlist for that - ruclips.net/p/UUMO7p4oXcPbgk_yTSHK7QlkSg You can join also with - ruclips.net/channel/UC7p4oXcPbgk_yTSHK7QlkSgjoin
your expiation is very good, but when you uploaded a videos in series, why are you showing the repeated process(vpc, ec2, routes, lb) every time?. If we you can save that time you can upload small videos and cover all the buttons. Sorry it's just my feedback.
I appreciate you feedback and it is valid. But I have thousands of viewers who are only interested in one topic and if i skip the networking part in any of my video then they will not understand why i am working private or public subnet or why i created the VPC in the first place. So that is the reason i try to always prepare the setup from the scratch although it might be repeated for you but to improve that experience i have provided the time stamp in the description so that you can skip the networking part which you feel repeated
Have to put existing EC2 instances one in backend and frontend in auto scaling group is it possible ? Do i have to create new instance and do all installation part
I had the same question so I investigated, AWS will try to keep the number of instances near of the desired number, if the metric is reached then the number of EC2 instances increases and the same happens if the demand is very low, the number of instances will decrease but always above the min number
Hi Rahul! Could you please explain me when the 3rd instance is created by ASG due to more HTTP load, how will the 3rd instance has the same configured application and DATA which are in 1st and 2nds instances ? Usually USER DATA has only information which needs to be installed but not completely configured for production. The 3rd instance will be created as per the Template we create.
Hi Rahul, Can I know the information about membership, If I join the membership of any (beginner/intermediate), Have you uploaded concept videos there and Do I see that videos? Thanking you.
@@RahulWagh Hi, I created two private subnets(AZ1a, AZ1b) and associated them with a new private route table. There is no IGW or NAT GW connected with that. Then I created a Target group. Then I configured a Load balancer with public subnets in two different Availability zones(AZ1a, AZ1b). After that, I created Auto Scaling group with two private subnets. But the the health check is failed and instances are being destroyed and recreated again and again. So, what would be the reason for this

This has to be the best AWS tutorial ever come across, Thanks @Raul
Glad it was helpful!
Crisp and clear explanation in layman's term

Auto scaling support which type of scaling policy it's vertical or horizontal scaling?
It is an horizontal scaling because we are increasing and decreasing the number of instances

How will my nodejs code be deployed from github to these auto-scaled instances?
Very good information
So nice of you
Very detailed video, thanks!
You're welcome!
If possible can you please explain instance refresh for ASG.
Where do we requested that what type of instances we want on demand or Spot instance.
@rahul thank you for sharing knowledge, I tried this same to same setup but my instances are not getting public IPs and hence none of the instances gets healthy in Target Group. please advice If I am missing anything.
Public IPs has nothing to do with the health of ec2 please check the instance user data script if that has been running properly or not
What case we use load balancer and Autoscaling?
Load balancer will not scale up or scale down instances but instead it will just distribute the traffic equally but autoscalling will increase and decrease the instances

how can we connect private subnet instances with ALB, is it possible?

You have a max count always with you which you can set to high but use scaling based on memory usage as well as cpu to have more control
