Recovery Oriented Computing
Recovery Oriented Computing (ROC) is a design philosophy and methodology focused on building computer systems that prioritize rapid recovery from failures rather than attempting to achieve perfect reliability. It acknowledges that failures are inevitable in complex systems and shifts the emphasis from preventing all failures to minimizing downtime and data loss when they occur. This approach involves designing systems with features like automated failure detection, isolation, and recovery mechanisms to maintain service availability.
Developers should learn ROC when building large-scale, distributed, or mission-critical systems where high availability is essential, such as cloud services, financial platforms, or healthcare applications. It is particularly valuable in environments where failures can have significant business or safety impacts, as it helps reduce mean time to recovery (MTTR) and improve overall system resilience. By adopting ROC principles, teams can create more robust systems that gracefully handle unexpected issues without requiring manual intervention.
