Amazon RDS for Oracle Now Supports Managed Disaster Recovery and Data Proximity with Cross-region Read Replicas
Starting today, Amazon Relational Database Service (RDS) for Oracle supports Cross-region Read Replicas with Oracle Active Data Guard. Amazon RDS for Oracle makes it easy to create physical standby DB instances in different AWS Regions from the primary DB instance. It fully manages the configuration of Active Data Guard, and replicates data over secured network connections between a primary DB instance and its replicas running across regions.
