Network Load Balancer

A Network Load Balancer is designed for high-performance network traffic and operates at the connection/transport layer.

Why it matters

It fits use cases that need network-level load balancing characteristics.

How it works

Listener → target group → network connection → target.

Real-world example: Use an NLB when the workload requires network-level behavior rather than HTTP-aware routing.

Core Concept

NLB is designed for TCP, TLS and UDP use cases where connection behavior and performance requirements differ from HTTP-aware routing.

Choose it when the application needs network-level load balancing characteristics.

What you should remember

Key idea

NLB is designed for TCP, TLS and UDP use cases where connection behavior and performance requirements differ from HTTP-aware routing.

Key idea

Choose it when the application needs network-level load balancing characteristics.

Real-world example

Use a realistic cloud workload and focus on the responsibility of this AWS service.

User → AWS service → application → data / response

Choose the service that matches the responsibility instead of forcing every workload into one resource.

# Conceptual workflow aws-service --resource example # Verify configuration → test → monitor → clean up
Practice tip: Build the smallest possible lab, verify the result, then remove resources you no longer need.
