Designing for failure - architecting fault-tolerant system
summary
Explains concrete fault-tolerance tactics: hardware and geo redundancy, caching, idempotent requests, sending commands instead of full objects, audit logs and Enterprise Integration Patterns, and automated CI and restore tests. Gives numbers: a memory-first case hits limits at 66 GB per node and an attempted scale into 200 shards breaks due to hot keys. Recommends clone-and-flip deployment with fleet-level integration tests and metric-driven rollbacks; emphasizes postmortems and verifying assumptions.
