AWS has introduced a new execution block for Amazon Application Recovery Controller (ARC) Region switch, specifically targeting Amazon RDS databases running Oracle Data Guard. This addition automates the manual steps previously required to reverse roles between a primary instance and its read replica during a regional impairment. The feature enables bounded recovery times for multi-region workloads by orchestrating the failover process without human intervention.
- Automates Oracle Data Guard role reversal in RDS during regional outages
- Integrates directly with ARC Region switch for end-to-end orchestration
- Eliminates manual promotion steps, reducing recovery time objectives (RTO)
- Specifically supports multi-region Oracle workloads on Amazon RDS
Fleet impact: For ExaCC/RAC and Aurora fleets, this confirms AWS is standardizing automation hooks for Oracle Data Guard across managed RDS. Ensure your ARC recovery plans explicitly include this new execution block to achieve consistent RTOs during regional failovers of your Oracle RDS instances.
