Reliability¶
Reliability is the ability of a system to perform its intended function consistently and without failure over a given period. A reliable system behaves predictably under normal and adverse conditions.
Reliability is built through defensive programming, thorough testing, graceful error handling, circuit breakers, retries with backoff, and observability practices that surface failures quickly. It is closely related to availability but focuses on correctness and consistency rather than uptime alone.
