Prerequisites: To use this check, you must opt in to Cost Optimization Hub and AWS Compute Optimizer.

This Recommendation identifies Aurora clusters that should be rightsized to optimize cost and performance.

What it does

• Identifies Aurora clusters that are over-provisioned or under-provisioned
• Provides estimated cost savings from rightsizing clusters
• Uses AWS Trusted Advisor recommendations to identify optimal rightsizing targets

Recommended actions

• Rightsize Aurora clusters to match actual resource utilization
• Review CPU, memory, and I/O utilization metrics
• Consider performance requirements when rightsizing
• Test application performance after rightsizing to ensure requirements are met
• Monitor Aurora cluster performance metrics during and after rightsizing
• Consider Aurora Serverless v2 for variable workloads that may benefit from auto-scaling
