The Hidden Cost of Slow Autoscaling, with John Ford

Forced platform migrations are usually treated as something to survive. At Scout24, a mandatory OS migration became an opportunity to rethink Kubernetes autoscaling, node provisioning, and infrastructure efficiency.

John Ford explains how Scout24 moved its EKS-based Infinity platform from a polling autoscaler and over-provisioned capacity to Karpenter and Bottlerocket. The result was faster node startup, a safer migration path, and about a 30% infrastructure reduction without major downtime.

In this interview:

  • Why two-minute node provisioning forced a 25% capacity buffer

  • How Karpenter made the Bottlerocket migration safer

  • What broke around EC2 metadata, AWS SDKs, and cgroups

  • How the new foundation enables Spot, ARM, and GPU workloads
