Creating Amazon Network Load Balancer

Overview

Amazon’s Network Load Balancer operates on the fourth layer of the Open Systems Interconnection (OSI) model, enabling efficient handling of millions of requests every second. Upon receiving a connection request, the load balancer intelligently chooses a target from the designated target group based on the default rule. It then proceeds to establish a TCP connection with the selected target, utilizing the port specified in the listener configuration.
