"Systems fail. The question isn't if, but when. Resilience is about designing for failure and recovering gracefully."
Reliability means systems work as expected under normal conditions. Resilience means they continue to function—perhaps degraded—even when things go wrong.
We design for both: building reliable systems through rigorous testing and engineering practices, and ensuring resilience through redundancy, fallbacks, and graceful degradation.
Systems continue operating despite component failures through redundancy and isolation.
Reduce functionality rather than fail completely when resources are constrained.
Detect issues early through comprehensive observability and intelligent alerting.
Rapid recovery from catastrophic failures through backups and tested recovery procedures.
Deliberately inject failures to validate system resilience and discover weaknesses before they cause outages
Verify system behavior under expected and peak load conditions to prevent capacity-related failures
Simulated incident response exercises to practice recovery procedures and improve team coordination
