Multi-tier cache (L1 Caffeine in-process + L2 Redis) with circuit breaker prevents database stampede on Redis timeout/failure via graceful fallback. Reduces single point-of-failure risk: critical for ops teams scaling distributed systems without cascade outage.

To design a solution, we must first analyze how cache failures manifest as systemic outages. Consider a standard read-through caching pattern:
[Client] ---> [API Gateway] ---> [Product Service]
