Key topics include Karpenter's direct EC2 API provisioning (45–60s vs. 3–4 min for Cluster Autoscaler), the v1 API changes (NodePool replacing Provisioner, EC2NodeClass replacing AWSNodeTemplate), Spot interruption handling via SQS/EventBridge, disruption budgets, Prometheus metrics to monitor, and common gotchas with PodDisruptionBudgets and StatefulSets with EBS volumes. The guide also covers safe rollback procedures and acknowledges Karpenter's limitation: it cannot fix overprovisioned pod requests, which the author's company (Cast AI) addresses with a complementary product. ## Full article daily.dev links to this article rather than hosting it.
