Myths Debunked
“It works locally → production-ready”: 68% of failures stem from untested edge cases (network latency, race conditions)
“Retries are optional”: 40% of AWS outages come from cascading retry storms. Slack’s 2021 8-hour outage proves it
“Observability = logging”: Teams using tracing fix bugs 90% faster
Critical Data
APIs slow 4x under load (50ms → 200ms at 10k RPS)
Chaos testing halves outages
Downtime costs $5,600/min. Observability cuts resolution time by 42%
5-Pillar Survival Framework
Enforce timeouts (2s for DB calls, three retries max)
Log with 3Cs: Context, Cause, Consequence
Load test at 2x peak traffic
Simulate failures (CPU spikes, network splits)
Abstract I/O, keep logic concrete
