Fault Domain Design: Turning Blast Radius from 100% into a Tunable 1/N Parameter

The article presents a layered fault-domain strategy—physical anti-affinity, logical isolation (sharding, cluster groups, swimlanes, bulkheads), cell-based architecture, chaos-engineering validation, and quantitative governance metrics—to shrink the blast radius of a ten-million-QPS system from a fixed 100% to a controllable 1/N design parameter.
