AWS Expands Cross-Region Replicas for Amazon RDS for Oracle With Additional Storage Volumes

Amazon Web Services has expanded cross-region replica support for Amazon RDS for Oracle by adding the ability to use additional storage volumes. The update allows organizations running Oracle databases on AWS to scale storage more flexibly while maintaining cross-region replication for disaster recovery and read scalability. The enhancement is designed to support larger, more demanding Oracle workloads without requiring architectural changes or manual storage management. Customers can add up to three storage volumes of 64 TiB each, in addition to the primary storage, allowing greater flexibility.

Cross-region replication is a critical component of business continuity planning for enterprises running mission-critical databases. By supporting additional storage volumes for cross-region replicas, AWS reduces operational friction for database administrators and architects managing complex Oracle environments. The update enables more predictable growth, better alignment with recovery objectives, and continued use of managed RDS capabilities. For enterprises modernizing Oracle deployments in the cloud, the change supports more scalable and resilient architectures without sacrificing managed service benefits.
