RES03-04 Supporting DR Management

DR management monitors DR status and RPO metrics while enabling service switchover during disruptions.

  • Risk level

    High

  • Key strategies
    • Monitor the DR status in real time to understand the DR operational status.
    • Verify application-level data, compare synchronization data between AZs, and monitor RPO metrics.
    • In typical deterministic fault scenarios, automatic DR or switchover does not require manual intervention. It keeps services running smoothly while meeting the RPO/RTO requirements.
    • In typical sub-health fault scenarios, service degradation or proactive switchover ensures service continuity.
