As customers scale the EKS clusters and deploy more workloads, the number of pods managed by a cluster can grow easily above thousands of pods. Now, each of these pods will consume an IP address.

What CNI does EKS use?

Amazon EKS supports native VPC networking with the Amazon VPC Container Network Interface (CNI) plugin for Kubernetes. This plugin assigns an IP address from your VPC to each pod. The Amazon VPC CNI plugin is fully supported for use on Amazon EKS and self-managed Kubernetes clusters on AWS.
