RDS Optimize EOL Version

Opportunity Name:

RDS Optimize EOL Version


AWS Resource Type:

RDS and Aurora Database Instances


Opportunity Description:

AWS RDS and Aurora database instances running on older, end-of-life (EOL) versions of MySQL and PostgreSQL can incur significant costs due to AWS's Extended Support fees. This finder identifies such instances, providing visibility into potential cost-saving upgrade opportunities before the onset of these fees.

Please see this important notification by Amazon: Extended Support for MySQL and PostgreSQL databases


Criteria for identifying the opportunity:

  • Scan customer AWS accounts for RDS and Aurora database instances on versions reaching AWS end-of-life support.
  • Identify instances eligible for Extended Support fees after AWS-defined EOL dates.
  • Annual cost, extrapolated from the last 31 days of usage, exceeds the annual public cost threshold (default $100).
  • Instances must have been stable (existing) for at least 31 days.


Potential savings (range in % on annual basis):

  • Savings are estimated as the difference in costs by avoiding RDS Extended Support fees for the coming year.
  • The savings increase as the date approaches the start of Extended Support.

Other considerations:

  • Performance impact: Upgrading database versions should be carefully planned to avoid potential performance regressions or incompatibilities.
  • Data loss considerations: Ensure backups and snapshots are taken before attempting any version upgrades to prevent data loss.
  • Security concerns: Review the security implications of new database versions to ensure they meet your organization's compliance and security standards.
