# Karpenter Example
Configuration in this directory creates an AWS EKS cluster with [Karpenter](https://karpenter.sh/) provisioned for managing compute resource scaling.
Configuration in this directory creates an AWS EKS cluster with [Karpenter](https://karpenter.sh/) provisioned for managing compute resource scaling. In the example provided, Karpenter is running on EKS Fargate yet Karpenter is providing compute in the form of EC2 instances.
