Production Solution & Architecture
Monitoring tells you whether known failure modes are happening. Example: CPU is high, disk is full, or the service is returning 500 errors. Observability helps you understand unknown failure modes by exposing enough telemetry to ask new questions without shipping new code. Example: "Only users in one region using one payment method are slow after version 2.4.1." Monitoring is usually dashboard and alert focused. Observability includes metrics, logs, traces, events, profiling, and good metadata so engineers can investigate systems they do not fully predict in advance. You need both: monitoring for fast detection, observability for fast explanation.
