#vpc-cni

A benchmark report comparing network and application performance of VPC CNI and Cilium CNI across 5 scenarios (kube-proxy, kube-proxy-less, ENI, tuning) in an EKS environment

How Pod IPs on EKS consume subnet addresses, VPC NAU, and branch ENI limits, and how to keep Karpenter's instance-size fallback from turning into IP exhaustion through NodePool and VPC CNI settings.

Dissects the internals of Amazon VPC CNI along three axes. The L3 routed mode datapath (veth, ip rule, 169.254.1.1), ipamd's warm pool, Prefix Delegation, and IP cooldown algorithms, and the eBPF-based NetworkPolicy architecture
