AWS Automates Oracle Data Guard Failovers with ARC Region Switch
AWS just dropped the RDS Switchover Read Replica execution block in ARC Region switch, letting you automate failover orchestration for multi-Region Oracle Data Guard databases without manual intervention. This means zero-data-loss switchovers during planned failovers and lightning-fast read replica promotion when things go sideways—plus cross-account support for centralized recovery management across your org.
