The original title is: "EKS node autoscaling with Karpenter: just-in-time capacity without node groups"

Short summary

Karpenter auto-scales EKS clusters based on actual pod demand instead of pre-sized node groups, reducing waste and simplifying capacity management. It separates scheduling intent (NodePool) from AWS configuration (EC2NodeClass), enabling granular resource matching. Built-in consolidation and drift controllers automatically optimize costs and compliance without manual intervention.

• •Scales from pending pod demand rather than static node-group templates
• •NodePool and EC2NodeClass separate capacity policy from cloud infrastructure
• •Automatic consolidation and drift detection eliminate manual right-sizing and AMI rollover work
