Amazon RDS Custom for Oracle now supports Multi-AZ deployments, providing high availability for business critical workloads. Amazon RDS Custom for Oracle is a managed service for running Oracle databases on AWS, with ability to customize the database environment and underlying operating system. With Multi-AZ deployments, RDS Custom for Oracle synchronously replicates data between two Availability Zones, and performs an automatic failover in case the primary database instance becomes unavailable so that customers benefit from higher availability.
To set up an RDS Custom for Oracle database instance with Multi-AZ deployment, customers can specify their configuration when they create their database instance. RDS Custom automatically provisions primary and standby database instances in the different availability zones, and synchronously replicates data to the standby instance. If the primary database instance becomes unavailable, RDS Custom automatically fails over to the standby instance without any manual intervention. To learn more about Multi-AZ deployments, see Amazon RDS Custom for Oracle user guide.
Multi-AZ deployment option is available in all AWS regions where RDS Custom for Oracle is available. For pricing details, refer to the RDS Custom for Oracle pricing page.
