RDS Retype Aurora Serverless

Opportunity Name:

RDS Retype to Aurora Serverless


AWS Resource Type:



Opportunity Description:

This opportunity identifies Amazon RDS instances with low average utilization and sporadic usage patterns that could benefit from migrating to Aurora Serverless. Aurora Serverless automatically scales compute capacity in response to application workload changes, potentially leading to significant cost savings.


Criteria for identifying the opportunity:

  • Analyze RDS instance usage metrics over the past 30 days for sporadic usage patterns.
  • Identify instances where Aurora Serverless's automated scaling and billing per second could reduce costs.
  • Annual cost, extrapolated from the last 31 days of usage, exceeds the annual public cost threshold (default $100).
  • Ensure instances are compatible with Aurora Serverless, considering database engine versions and features.


Potential savings (range in % on annual basis):

  • Projected cost savings are 30% of the current RDS cost after migrating to Aurora Serverless.
  • Actual savings will depend on the specific usage patterns and configurations of the identified RDS instances.

Other considerations:

  • Performance impact: Migrating to Aurora Serverless may change the performance characteristics due to its auto-scaling feature. Testing is recommended to ensure application requirements are met.
  • Data loss considerations: Ensure that all data migration steps are properly followed and backups are taken before migration to prevent any data loss.
  • Security concerns: Review and adjust security settings as necessary to match the original RDS instance configurations in the Aurora Serverless environment.
