Overview
Reliability engineering focuses on ensuring that a system performs its intended function under specified conditions for a specified period. In software, this is closely related to Site Reliability Engineering (SRE).
Key Metrics
- MTBF (Mean Time Between Failures): The average time a system runs before failing.
- MTTR (Mean Time To Repair): The average time it takes to fix a failure.
- Availability: The percentage of time a system is operational.
Techniques
- Redundancy and failover.
- Rigorous testing and monitoring.
- Root cause analysis of failures.
