Tanat Lokejaroenlarb shares the complete journey of replacing EKS Managed Node Groups and Cluster Autoscaler with AWS Karpenter. He explains how this migration transformed their Kubernetes operations, from eliminating brittle upgrade processes to achieving significant cost savings of €30,000 per month through automated instance selection and AMD adoption.

You will learn:

• How to decouple control plane and data plane upgrades using Karpenter's asynchronous node rollout capabilities

• Cost optimization strategies including flexible instance selection, automated AMD migration, and the trade-offs between cheapest-first selection versus performance considerations

• Scaling and performance tuning techniques such as implementing over-provisioning with low-priority placeholder pods

• Policy automation and operational practices using Kyverno for user experience simplification, implementing proper Pod Disruption Budgets
