Guide to Load Balancer Listeners
What it is: A Listener in Load Balancing is a process that checks for connection requests. It is configured with a protocol and a port for front-end (client to load balancer) and backend (load balancer to back-end instances) connections. The common protocols include HTTP, HTTPS, TCP, and SSL.
Why it is Important: Load Balancer Listeners allow the Load Balancer to distribute the incoming traffic evenly across multiple target instances, which enhances the performance and fault tolerance of your applications.
How it Works: When a client sends a request, the listener checks the load balancer for connection requests from clients using the specified protocol and port. Once a request is received, it decides where to route the request based on the configured load balancing algorithm.
Exam Tips: Understanding how Load Balancer Listeners work is fundamental in Exam. You should be aware of the different types of listeners, their protocols, and how they operate. Note that you may encounter questions about the routing algorithm, ensuring that the listener is configured correctly for the type of connection and traffic you expect to manage, and the implications of these configurations on the performance and reliability of your applications.
Answering Questions on Load Balancer Listeners: 1. Understand the different types of Load Balancers and their corresponding listeners 2. Familiarize yourself with the effects of different configurations on application performance and reliability 3. Be able to explain how a listener routes traffic to target instances 4. Understand the function of health checks in conjunction with Load Balancer listeners.

Load Balancer Listeners practice test
Listeners are components of Elastic Load Balancers that take incoming requests and distribute them to one or more registered backend instances. They are configured with a protocol and port number for incoming connections, along with a default rule defining how to route requests to target instances. Listeners support various protocols such as HTTP, HTTPS, TCP, and TLS. They process incoming connections and establish sessions or connections to the appropriate target instance based on the configured routing rules.
