These instances may be remnants of retired applications, paused development environments, or workloads that were migrated elsewhere. If an instance shows no active connections and sustained inactivity across CPU and memory metrics, it is likely idle and generating unnecessary costs. ## Billing model The pricing dimensions that drive this cost. RDS instances are billed based on the selected instance class (vCPU and memory), per second with a 10-minute minimum after a billable status change, while running. Additional charges may apply for storage, backup retention, Multi-AZ replication, and provisioned IOPS-regardless of workload activity. ## How to detect 5 checks to find it in your estate. - Identify RDS instances that have been running continuously during the lookback period - Review performance metrics to confirm low or zero CPU and memory usage - Check connection logs and query metrics to validate the absence of active database traffic - Confirm with owners or application teams whether the instance is still in use - Evaluate whether snapshots or backups exist that could support future recovery needs ## How to fix How to remove the waste. Delete the inactive instance after validating that it is no longer required, taking a final snapshot if data retention is necessary. Stopping the instance only suits short pauses: RDS automatically starts a stopped instance after 7 consecutive days, and provisioned storage and backups are still billed while it is stopped. Review and remove associated resources such as storage, backups, or read replicas to fully eliminate residual costs. ## Documentation Vendor references for pricing and configuration. - [RDS Pricing aws.amazon.com](https://aws.amazon.com/rds/pricing/) - [Monitoring RDS with Amazon CloudWatch docs.aws.amazon.com](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/MonitoringOverview.html) - [Stopping an Amazon RDS DB instance temporarily docs.aws.amazon.com](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_StopInstance.html) ## Related inefficiencies [Browse the library](https://www.pointfive.co/efficiency-hub) - AWS RDS CER-0299 ### [Orphaned RDS Backup Storage After Database Deletion](https://www.pointfive.co/efficiency-hub/inefficiencies/orphaned-rds-backup-storage-after-database-deletion) An RDS database instance is deleted but its manual snapshots or retained backups remain. Unlike automated backups tied to a live instance, these backups persist independently and continue generating storage costs despite no longer...

After this period, the instance is automatically restarted and resumes incurring compute charges - even if the database is still not needed....

Unlike underutilized resources, these clusters are completely idle-showing no query activity, background processing, or usage... Databases --- Source: the public page above.
