The Fallacy of 100% Availability
Failures are inevitable in distributed systems. The goal isn’t to eliminate failures—it’s to build systems that can gracefully handle them.
Netflix’s Chaos Engineering
Netflix pioneered chaos engineering, which involves intentionally causing failures in production to ensure the system can withstand them. Tools like Chaos Monkey help with this practice.
Circuit Breakers: A Critical Resilience Pattern
Circuit breakers prevent repeated failed calls to a service, giving it time to recover. Libraries like Hystrix (Netflix) and Resilience4j implement this pattern.
Spotify’s Failure Retries
Spotify uses smart retry strategies with exponential backoff and jitter to handle transient failures without overwhelming services.
