## What it is
The AWS VPC CNI plugin is a Kubernetes networking plugin that assigns VPC IP addresses to pods using Elastic Network Interfaces on AWS. It consists of a CNI plugin that wires pod networking and an ipamd daemon that manages a warm pool of IP addresses per node.

## Use cases
- give Kubernetes pods routable VPC IP addresses on AWS
- run EKS clusters with native VPC networking
- manage warm pools of pod IPs to speed up pod scheduling
- configure max pods per node based on ENI IP limits
- set up IAM policies for the CNI plugin

## When to choose
- you run Kubernetes on AWS or EKS and want pods to have native VPC networking
- you need pods to be directly reachable from other VPC resources
- you want AWS-supported IPAM with warm IP pools for fast pod startup

## When to avoid
- your cluster runs outside AWS or you don't need VPC-native pod IPs
- you prefer overlay networking like Calico or Cilium with network policy features
- you need a cloud-agnostic CNI across multiple providers
