AWS Application Load Balancer (2023) Step-by-Step Tutorial with Target Groups and EC2,

In this video, we will introduce you to AWS Application Load Balancer, a service that distributes incoming traffic across multiple targets, such as EC2 instances, Lambda, containers, and IP addresses.
You ll learn about different components of Application Load balancer and will explore the basics of creating target groups and listeners, and how Application Load Balancer intelligently routes traffic based on the content of the request and the health of the targets.
We will also discuss the Path-based routing feature, which allows you to route traffic to different target groups based on the request's characteristics.
If you're looking to scale your applications and improve their performance, AWS Application Load Balancer is a powerful tool to consider. Check out this video to learn more about how it can benefit your business.

[@masami1986]

I have a service running in two clusters and two target groups pointing to each one, how can I have a balancer routing traffic from port 445 to one of the target groups no mattering the uri path

[@AchmadBadra]

How to set https on it? I still confused if is set any cert based on own domain, then redirect it to alb from domain dns?

[@matthewsmithwarren2]

Hi. Thanks for making this video. Will you provide a screenshot or detailed instructions on the ALB-SecurityGroup? At 18:11, you mention this selection saying to allow traffic in both directions with ports for listeners and health check ports. And then you pick alb02-sg-0323 but never show what this is. This is where my app is struggling so I appreciate any support. Thank you.

[@BeCloudGuru]

@Matthew, I can better help if you tell me how you currently have set up your listeners and security groups and also tell me about the ports/protocols your app is using.

[@abduljabbarazam943]

The security group is created at kzbin.info/www/bejne/rKmZqX-upth3m80

[@538sureshs7]

Can you put video for bad gateway and un healthy target group

[@user-gc4hs5ke3m]

what are rules you craeted in alb security group

[@hamidapremani6151]

Very well-explained. I followed every detail of your video. However, still getting 504 error. Please help. Did the entire setup on default VPC in N.Virginia. SG is port 22 and 80, it is attached to igw and route table is configured with igw as well. I am not sure why I am getting the error .

[@BeCloudGuru]

@Hamida, If it default vpc then route table would have already been pointing to igw, did you change that?

[@hamidapremani6151]

@@BeCloudGuru somehow my RT was not pointing to IGW. Probably may have done something previously, which I don’t even recall. Planning to follow the same in a different region this time where I haven’t refactored the settings. Thanks for responding.

[@BeCloudGuru]

@hamidapremani6151 Please share the results once you do it in another reason, I am sure you would be able to make it work.

[@probablyworse-2838]

[@BeCloudGuru]

@prabablyworse, this is the answer to your question " do you make it var/www/html/cart for cart and var/www/html/image for image?". Please let me know if you have any other questions on this.

[@BeCloudGuru]

@user-vl1rc , this error normally indicates Indicates that either the load balancer or the registered instances are causing the error. Check that your instances are registered and they re healthy as well.

@amolrekhawar, what is not working? If you follow it step by step without missing a step, it ll surely work. Let me know if you still face the problem

@@BeCloudGuru this site cant be reached

[@BeCloudGuru]

In that case, check the security groups to determine whether relevant port and protocols are allowed or not. Also, check your web servers without ALB whether the site is reachable or not.

@amolrekhawar525 Hi Amol, I was just wondering if it worked for you or not.
