Database Blog

This article discusses a solution for improving cost visibility in multi-tenant Amazon RDS instances using Performance Insights and Amazon Athena.

  • Challenges in multi-tenant database cost management and resource allocation
  • Uses Performance Insights to track database load and user-level resource consumption
  • Integrates Performance Insights metrics with AWS Cost and Usage Reports (CUR)
  • Enables precise cost attribution to individual tenants based on actual database usage
  • Provides insights for optimizing database resources and implementing chargeback models

The solution allows service providers to: • Understand resource consumption per tenant • Identify periods of database under-utilization • Make data-driven decisions about capacity planning • Potentially reduce costs by moving to serverless options
