Do You Trust Your PodDisruptionBudgets? You Shouldn’t! - Kārlis Akots Gribulis, Saxo Bank

This talk, presented by Kārlis Akots Gribulis from Saxo Bank, explores the reliability of PodDisruptionBudgets in Kubernetes. The speaker discusses how these budgets can fail due to factors like priority classes, Quality of Service classes, and resource pressure, potentially compromising critical workloads during upgrades or node failures. Through real-world failure scenarios, the session highlights the impact on cloud-native platforms and provides practical strategies for testing and reinforcing disruption policies to ensure workloads remain secure.
