Can this skill help with AWS cost savings?

Yes, it provides implementation patterns for node consolidation and Spot instance integration that can reduce AWS compute bills by 20-70%.

Can I use this with Infrastructure as Code?

Absolutely. The skill includes workflows for managing Karpenter via Terraform and Helm, ensuring your autoscaling configuration is version-controlled.

How does Karpenter differ from Cluster Autoscaler?

Karpenter provisions nodes directly via EC2 APIs in seconds, bypassing the limitations of Auto Scaling Groups used by Cluster Autoscaler, which typically takes minutes.

Does it support the latest Karpenter v1.0+ API?

Yes, the skill is updated for the modern Karpenter API, focusing on NodePool and EC2NodeClass resources rather than the deprecated Provisioner specs.
