Opportunity Name:
OpenSearch GP2 to GP3 Volume Type Change
AWS Resource Type:
OpenSearch Domain
Opportunity Description:
This finder identifies OpenSearch domains using GP2 volumes for storage and recommends changing these volumes to GP3. GP3 volumes offer better performance and lower cost compared to GP2 volumes, making this change beneficial for cost optimization and potentially enhancing performance.
Criteria for identifying the opportunity:
- OpenSearch domains utilizing GP2 volumes are targeted.
- Annual cost, extrapolated from the last 31 days of usage, exceeds the annual public cost threshold (default $100).
- Domains not tagged with 'cloudfix_dont_fix_it' to exclude them from processing.
Can CloudFix apply an automatic fix?
No
Other considerations:
- Performance impact: Changing from GP2 to GP3 may result in different performance characteristics. Users should evaluate the impact based on their specific workload patterns.
- Data loss considerations: The change from GP2 to GP3 does not inherently risk data loss, but as with any significant infrastructure change, a recent backup is advisable.
- Security concerns: There are no direct security implications of changing volume types, but ensuring that encryption settings are consistent is recommended.
