Everything on System Reliability

Distributed system failures are predominantly caused by resource saturation, latency, and unavailability, not complex logic errors. These three rules simplify resilience design.

Impact: Focuses engineering efforts on high-impact failure modes, improving system stability and reducing mean time to recovery.

Scaling is the most frequent cause of failure in complex systems due to unforeseen resource contention (CPU, network, memory) that only manifests at specific thresholds.

Impact: Necessitates a shift toward proactive chaos testing and aggressive scale anticipation to prevent systemic collapses.
