Question

How to set up rules for Application Load Balancer? Are there certain set of steps that need to be followed?

Answer 1

You can configure rules for each of your listeners you configure for the load balancer. The rules include a condition and a corresponding action if the condition is satisfied. The condition will be a path URL path of a service (e.g. /img) and action is forward. Once you have set this up, the load balancer will use the rules to determine the service to which the request must be routed.
