(Preview) RDS Retype IO Optimized

Opportunity Name:

RDS Retype IO Optimized

 

AWS Resource Type:

RDS Aurora

 

Opportunity Description:

This opportunity targets Amazon RDS Aurora instances that are not currently utilizing the I/O-Optimized storage type. With the launch of Aurora I/O-Optimized instances and storage, AWS has provided a solution designed for I/O-intensive applications, available for Gen5+ instances. CloudFix can identify and recommend upgrading to these I/O-Optimized instances/storage, aiming for significant cost reductions while maintaining or enhancing performance for I/O-intensive workloads.

 

Criteria for identifying the opportunity:

  • Analyze average instance costs over the past 90 days to calculate potential savings.
  • Recommend upgrade to I/O Optimized instances/storage if the cost reduction rate exceeds 15%.
  • Target Gen4 or earlier instances for upgrading to Gen6, ensuring Aurora version compatibility.
  • Annual cost, extrapolated from the last 90 days of usage, exceeds the annual public cost threshold (default $100).

 

Potential savings (range in % on annual basis):

  • Targeting up to a 30%-40% reduction on the bills for I/O-intensive applications.
  • Savings calculations factor in the increased costs of I/O-optimized instances and storage against the elimination of IOPs costs.
  • Actual savings will depend on the specific usage patterns and configurations of the customer's Aurora instances.

 

Can CloudFix implement the fix automatically once I accept the recommendation?

No

 

Other considerations:

  • Performance impact: Upgrading to I/O-Optimized instances may enhance performance for I/O-intensive applications, but it's important to assess the workload compatibility.
  • Data loss considerations: Ensure that all data is backed up before making any changes to the storage type or instance generation to prevent any potential data loss.
  • Security concerns: Verify that the new instance types and storage configurations do not alter any existing security postures or compliance requirements.
  • Version compatibility: Ensure that the Aurora MySQL or PostgreSQL versions are compatible with the I/O-Optimized instances.
