Why Kubernetes Utilization Is Stuck Below 40%
Kubernetes was supposed to scale itself — so why do real-world clusters rarely run above 30–40% utilization? In this Techstrong TV interview, director of product and technology and co-founder at PerfectScale Eli Birger joins Mike Vizard for a candid conversation about the gap between Kubernetes’ promise and what’s actually happening in production. Eli unpacks why developers’ fear of failure leads to chronic over-provisioning, why monitoring tools were never built to solve this, how AI-driven vibe coding is exploding cluster costs, and why autonomous, battle-tested algorithms — not AI black boxes — are the safest path forward. Plus: keep-it-simple advice, the case for platform engineering, and how to think about Day 2 operations as a continuous optimization process.
