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 bufferHow Karpenter made the Bottlerocket migration saferWhat broke around EC2 metadata, AWS SDKs, and cgroupsHow the new foundation enables Spot, ARM, and GPU workloadsSponsorThis episode is sponsored by LearnKube — get started on your Kubernetes journey through comprehensive online, in-person or remote training.More infoFind all the links and info for this episode here: https://ku.bz/DdmVC2_7vInterested in sponsoring an episode?
