What's Inside

Section 1: The Tradeoffs of Optimization

Why performance, reliability, and cost are one constrained system — not three separate levers

Section 2: Where the Money Actually Goes

The real breakdown of Kubernetes spend: oversized requests, idle GPUs, mismatched nodes, slow-to-scale-down autoscalers

Section 3: The Four Risks of Cutting Too Far

OOM kills, CPU throttling, over-provisioning, and unschedulable pods — and the mechanics behind each

Section 4: VPA, HPA & Node Autoscaling, Explained

What each tool actually does, where they conflict with each other, and where they quietly fail

Section 5: The PerfectScale Approach

8 principles for optimizing safely — risk ranking, granular policies, bi-directional right-sizing, HPA/revision/node-awareness, and more
