Creating Amazon Application Load Balancer

Overview

The Amazon Application Load Balancer operates at the application layer, which corresponds to the seventh layer of the Open Systems Interconnection (OSI) model. Upon receiving a request, the load balancer assesses the listener rules in a hierarchical order to identify the appropriate rule to apply. Subsequently, it chooses a target from the target group associated with the rule’s action.
