AWS Distribute HTTP request with Load Balancer

Question

Using AWS, I want to:

• Distribute http request sending over several different IPs
• Send this requests without using proxy
• Send this using Elastic Load Balancer and AutoScaling Group
• Send these requests from one instance to several instances in AutoScaling Group
• Each of those several instances assigns different IP to the incoming request so output the request in its IP

How do I do this? Is there anyway to set up load balancer just to send through http request? I want each http request to have different IP address.

Answer 1

So, basically you're willing to connect to EC2 instances behind a ELB and willing to know, on the EC2 instances, the original IP address of the connection, not the ELB's IP address.

If my understanding of your question is correct, then the answer is

• Use TCP listener on the ELB, instead of HTTP listeners.
• Enable Proxy Protocol on the ELB
• on your EC2 instances, collect the original IP address
