MemoryDB Cluster Idle
Cluster nodes bill by the hour while running, and MemoryDB additionally bills for the durable transaction log independent of request volume.
Free to start. No card. The playground just needs your work email.
AWS
Found, explained, handed over.
Findings with a dollar figure attached, idle, oversized, orphaned, unscheduled and undiscounted spend.
Detect
ZopNight checks this automatically across AWS, with read-only access to the account.
Explain
Every finding says exactly what to change: Delete the idle MemoryDB cluster. Where the saving can be proven it is priced; where it cannot, the finding says so.
Fix
The finding opens with the fix already written out, step by step, so it is one ticket, not an investigation.
- Applies to
- MemoryDB Clusters on AWS
- The fix, by hand
- Confirm the cluster has zero connections (CloudWatch: CurrConnections == 0) for at least 7 days.
- Search application config / Secrets Manager for the cluster endpoint before deleting.
- Open MemoryDB → Clusters → select → Actions → Delete.
- Choose 'Create final snapshot' = Yes; name it descriptively.
- Validate cost drop in Cost Explorer 24h later.
These are the steps the finding carries in the product.
