[@abuzaransari3817]

my load balencer is working fine it routing the requests to both ec2 instace how ?

[@nebolos]

Hi Rahul. Thanks for this video, it was extremely helpful and I loved the way you always break things down so it is easy to follow along. I have a small request. Can you do a video on internal ALB + ASG?

[@RahulWagh]

You are welcome

[@rocktech2359]

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

[@RahulWagh]

The autoscaling will take care of incoming request but you need to make sure that you have setup suffcient number of ec2 instances upscaling count. Because load balancer is just balancing the incoming request but if you run out of ec2 instances then it will be a problem

[@rocktech2359]

@@RahulWagh by watching your video I have setup autoscaling group, and now I have created two instances. But now I have few more doubts. 1. I'm already using an instance and I did all the setup in it like Node.js installation, nginx installation, cicd setup and all required setup. So now using autoscaling launch template I have created two more instances. So do I again need to do all this setup or is there any ways my previous setup will reusable. And also if I need to do steps, do I need to do setup on each instance ?.

Thank you for this tutorial! I love the illustration of the entire infrastructure. I have one question. How can we configure Godaddy to point to the application load balancer?

[@RahulWagh]

You need to update the godaddy dns configuration

[@mhamadyahya1]

Do i need application load balancer , if ec2 is private instance ? and the requests data coming from ecs fargate ?

[@lalithkumar2750]

Thank u so much Ur videos are awesome

[@vijujk9295]

Is Really needed New VPC implementation for autoscalling , because i have already running two ec2 in aws default vpc now i want to do autoscalling can i do that with default vpc also target group select only production instance currently i have only one production instance in this case how to do auto scalling ?,in this case we use diffrent server for db used?give any suggestions

[@Микола-е9ю4ц]

Hey Rahul, One question that I need to clarify - why there in LoadBalancer you left Default Security Group (allow any inbound/outbound traffic on any host and ports) ? But new one, customer created Security Group (limit inbound protocol and port). Probably Default Security Group needs to remove ?

[@RahulWagh]

The default security group can be removed

[@ChandraShekar-zq8gv]

Greate Explanation brother..♥

[@ArunKumarD-y7t]

Hi Rahul or anyone, I have a doubt in EC2 security group, why the source of it is from internet not from load balancer?

[@RajBokade-g9w]

Great Explanation, A small question, If i have Spring boot application A and B, and application A communicates with B, so In case of auto scaling can application A of 1st ec2 instance communicate with application B of other ec2 instance.

[@RahulWagh]

@@RajBokade-g9w yes it can and it should done via route53 A records so that you do not need to worry about ec2 instance IPS

how to tweak fake network and auto scale instance ?

[@RahulWagh]

Why you wanna do that

[@bellamrahul6365]

@RahulWagh to see the effect of auto scaling , to see increase in instance if load increases on other instances

[@bellamrahul6365]

@@RahulWagh it would really great if u do a video demonstrating adding an instance if there is sudden spike of cpu usage due to increased traffic and auto scaling group adding an instance in this case
