AWS send http request through elastic load balancer

I am a beginner and trying to send http requests through elastic load balancer. Could anybody explain briefly about the steps that I need?

  • set up Elastic Load Balancer A
  • get DNS of the Elastic Load Balancer A
  • register EC2 instances to the Elastic Load Balancer A
  • send traffic to the DNS of Elastic Load Balancer A

But I have no idea what kind of configuration or set up I need to put in the EC2 instances that are to be attached to this Elastic Load Balancer A. Do I need to set up Listener? If so, how do I set this?

I just want to send http request under the ip of EC2s and Elastic Load Balancer A so that I get different IPs assigned to each requests.

Thanks a lot!

By default, Amazon EC2 instances behind an Elastic Load Balancer serve traffic on port 80 (HTTP). When creating the Load Balancer, you can configure which ports should receive traffic (80, 442, 1024+).

Think of it this way... The Load Balancer simply sits "in front" of the EC2 instances. If a user was to go directly to your EC2 instance directly (eg enter its IP Address in a web browser), they should see a website. Going to the Load Balancer does the same thing, but it distributes the requests amongst multiple EC2 instances.

So, in most cases, it's just a matter of running a web server or app on your EC2 instance running on port 80.
