Load Balancing Configuration

To get started balancing traffic between our three HTTP listeners, we need to set some options within HAProxy:

• frontend - where HAProxy listens to connections
• backend - Where HAPoxy sends incoming connections
• stats - Optionally, setup HAProxy web tool for monitoring the load balancer and its nodes
