In this article, I want to illustrate how the AWS Elastic Kubernetes Service allocates IPs for the cluster so you can better manage your platform! At every step, we will seek to understand what is happening in terms of IP allocation.

ENIs are attached to the nodes, providing a means of attaching IPs for each pod in the cluster. And some excess IPs are reserved to maintain this warm pool so that pods can obtain IPs faster and thus spin up quicker.

This component can be configured to choose how IPs are kept warm, and there are lots of settings you can look into.
