"I often see teams confusing "speed" with "consistency." In my experience, a system can be fast but still crash under a 24-hour load. If I want to implement a full-scale reliability test system, should I prioritize fault tolerance or resource management first? I've been documenting the differences-specifically how recovery testing and configuration testing fit into the mix. For those using CI/CD, how are you automating these long-term tests without slowing down your deployment cycles?"

Speed and consistency are distinct system properties; fast systems can still fail under prolonged load. Full-scale reliability testing should prioritize fault tolerance because resilient designs prevent cascading failures and enable graceful degradation during long-term stress. Resource management should follow, optimizing capacity, throttling, and leak detection once fault domains are well-defined. Recovery testing validates failover and automatic repair; configuration testing ensures safe defaults and reproducible deployments. For CI/CD, move long-duration soak tests to parallel pipelines, scheduled test windows, or dedicated reliability environments. Use failure injection, observability, automated triage, and canary/rolling releases to maintain deployment velocity.
