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.

Mastering Kubernetes Pod Affinity: From Node Rules to Anti‑Affinity Strategies

This guide explains how Kubernetes pod scheduling affinity—both node affinity and pod (anti‑)affinity—provides fine‑grained control over pod placement, covering hard and soft rules, practical YAML examples, scoring mechanisms, and a comparison with DaemonSets for high availability and resource isolation.
