Optimize Lambda Memory Allocation

Opportunity Name:

Optimize Lambda Memory Allocation

AWS Resource Type:

AWS Lambda

Opportunity Description:

AWS Lambda functions often have memory allocated beyond their actual usage needs, leading to unnecessary costs. CloudFix identifies these functions and recommends optimized memory settings based on actual usage patterns, potentially reducing costs without impacting performance.

Criteria for identifying the opportunity:

• Analyzes Lambda functions with memory allocation metrics available for the last 30 days.
• Focuses on functions where the actual memory usage does not exceed 10% of the allocated memory.
• Annual cost, extrapolated from the last 30 days of usage, exceeds the annual public cost threshold (default $100).

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

No

Other considerations:

• Performance impact: Properly sizing Lambda functions can improve execution efficiency without affecting performance.
• Data loss considerations: There is no risk of data loss when adjusting Lambda memory settings.
• Security concerns: Memory optimization does not impact the security posture of your Lambda functions.
