You can manually delete the following DB instances that are not in use to release resources:
- Primary DB instances
- Read replicas (RDS for Microsoft SQL Server does not support read replicas.)
- DB instances in the creating status cannot be deleted.
- If you delete a DB instance, its automated backups are also deleted and you are no longer charged for them. Manual backups are still retained and will incur additional costs.
- If you delete a primary DB instance, its read replicas are also deleted automatically. Exercise caution when performing this operation.
- Deleted DB instances cannot be recovered. Exercise caution when performing this operation.
- Log in to the management console.
- Click in the upper left corner and select a region and a project.
- Click Service List. Under Database, click Relational Database Service to go to the RDS console.
- On the Instance Management page, locate the target DB instance or read replica, and choose in the Operation column.
- In the displayed Delete DB Instance dialog box, click Yes. Refresh the Instance Management page later to verify that the DB instance or read replica has been deleted.
