VPC CNI en EKS: cómo dejar de pagar nodos que no usás
The article discusses how to optimize costs in Amazon EKS by utilizing Prefix Delegation in the VPC CNI plugin. This configuration can significantly increase the number of pods that can be scheduled on a node, potentially reducing EC2 costs by up to 75%. It also outlines the necessary steps to implement this solution effectively.
- ▪Prefix Delegation allows the VPC CNI plugin to request blocks of IPs instead of individual ones, increasing pod capacity.
- ▪For example, using Prefix Delegation on an m5.large instance can theoretically allow up to 434 pods.
- ▪Proper configuration requires adjustments to both the VPC CNI and kubelet settings to ensure Kubernetes recognizes the new limits.
