Waste signals
- CPU < 15% and connections < 5 over 14 days
- Storage allocated > 2× used
- Old engine versions paying legacy pricing
- No reserved-instance coverage on steady-state workloads
AWS RDS cost optimization
RDS is one of the highest-margin services AWS sells. Most production fleets carry 30-50% headroom that never gets used. TurboFinOps quantifies the headroom and recommends concrete target sizes.
Typical savings range$1,500-$12,000 / monthfleet of 20-80 RDS instances
Optimization levers
- Rightsize db.m5.4xlarge → db.m5.xlarge based on observed load
- Migrate to Graviton (db.m6g/m7g) for 10-20% savings
- Retire abandoned databases after backup snapshot
- Cover baseline with 1-year RIs (40-50% off on-demand)
Workflow
How TurboFinOps closes the loop
1. Scan
Enumerate instances, classes, CloudWatch CPU/conn/IO metrics.
2. Surface
Rightsizing and RI recommendations with confidence intervals.
3. Approve
Conflict guard + approval chain before modify-instance call.
4. Verify
d7/d14/d30 receipts on the bill, plus continued perf headroom check.
FAQ
Frequently asked questions
Does RDS rightsizing cause downtime?+
Modifying instance class typically triggers a brief failover on Multi-AZ deployments. TurboFinOps surfaces this and lets you schedule changes inside a maintenance window.
Can you recommend RI vs Savings Plan?+
Yes — the Commitment Optimizer compares Reserved Instances and Compute Savings Plans for your workload and shows confidence-scored coverage targets.
