RDS Optimization

Compute Optimizer for RDS

Supported engines: MySQL, PostgreSQL, Aurora MySQL, Aurora PostgreSQL.

Metrics analyzed: CPUUtilization, DatabaseConnections, NetworkReceive/TransmitThroughput, ReadIOPS/WriteIOPS, ReadThroughput/WriteThroughput, EBSIOBalance%/EBSByteBalance%, FreeStorageSpace. With Performance Insights: DBLoad, os.swap.in/out.

Finding classifications: Overprovisioned, Underprovisioned, Optimized.

Finding reason codes: CPUOverprovisioned, CPUUnderprovisioned, MemoryUnderprovisioned (high swap/OOM), NetworkBandwidthOver/Under, EBSThroughput/IOPSOver/Under, NewGenerationAvailable, NewEngineVersionAvailable.

Storage findings: EBSVolumeAllocatedStorageUnderprovisioned, EBSVolumeIOPS/ThroughputOver/Under, NewGenerationStorageTypeAvailable.

Multi-AZ Considerations

  • Changes apply to both primary and standby instances
  • Failover timing may be affected by instance changes
  • Multi-AZ reduces downtime during modifications

Read Replica Considerations

  • Recommendations synchronized with writer for promotion tiers ≤1
  • Smaller replica instances may increase replication lag

Storage Considerations

  • Storage can only be increased, not decreased
  • Storage type changes may require specific instance types
  • gp3 provides more flexible IOPS/throughput provisioning than gp2

Gotchas

  • DB instance modifications typically require brief downtime (5-10 min)
  • Engine version upgrades require compatibility assessment
  • Parameter group changes may be required after instance class change
  • Always take a snapshot before implementing changes
  • Performance risk scale: 0-1 Very Low, >1-2 Low, >2-3 Medium, >3-4 High

    This skill provides comprehensive instructions for analyzing and optimizing AWS costs. It incorporates security-conscious patterns, such as recommending sandboxed execution via the AWS MCP server and requiring deterministic Python scripts for all mathematical calculations to ensure data integrity and accuracy.
