## What it is
A Kubernetes controller that manages AWS Elastic Load Balancers for a cluster. It provisions Application Load Balancers for Ingress resources, Network Load Balancers for Service resources, and supports Gateway API resources.

## Use cases
- expose kubernetes services via aws load balancers
- provision ALBs from ingress resources automatically
- create NLBs for kubernetes services of type loadbalancer
- manage gateway api resources on aws
- automate load balancer lifecycle for eks clusters
- configure tls termination with aws acm certificates

## When to choose
- running kubernetes on AWS or EKS and need ingress/load balancer provisioning
- you want declarative management of ALBs and NLBs from kubernetes manifests
- you need Gateway API support with AWS load balancers

## When to avoid
- your cluster runs outside AWS or on a different cloud provider
- you need a general-purpose ingress controller with its own proxy like nginx or traefik
- you want load balancers not tied to AWS ELB services
