Previously, RDS storage autoscaling was limited to primary volumes, requiring manual provisioning of additional volumes for Oracle and SQL Server databases. This update allows up to three additional volumes to automatically scale storage as needed, reducing risks of downtime due to under-provisioning or wasted costs from over-provisioning.
The autoscaling feature monitors storage consumption and scales capacity up to defined maximums without interrupting database availability. It works with both new and existing instances, is included at no extra charge, and is available in all commercial AWS and GovCloud regions.
