⚙️ System Design for AI in ProductionSign in
Fault Tolerance and Graceful DegradationAI systems depend on flaky, slow dependencies (model providers, vector stores, tools), so they must degrade gracefully rather than fail hard. Circuit breakers stop calling a failing dependency so it can recover; fallbacks return a cached, simpler, or safe response when the primary path fails; timeouts and bulkheads contain failures. The goal is that one component's failure becomes a degraded experience, not an outage. Applied-AI interviews probe it because LLM dependencies fail often and naive designs turn a provider blip into a total outage.
