Design for Auto-Scaling

Design for Auto-Scaling — A Staff playbook focused on load modeling, scaling policy ownership, cost-performance tradeoffs, and capacity as a business negotiation — not just auto-scaling configurations.

This playbook is part of the full calibration library.

Staff interviews are decided on nuance — tradeoff framing, ownership boundaries, and failure anticipation. This playbook covers the depth that separates Senior from Staff+.
