Triage Guide: CloudFront Distribution Pricing Class Optimization

Understanding: Why should I care about fixing this issue?​

CloudFront distributions with 'PriceClass_All' include all possible edge locations, which means higher delivery costs. Optimizing the pricing class will exclude more expensive edge locations, reducing these costs.

Validate​

  • Data Source: This policy uses the AWS CloudFront distribution configuration data.
  • Manual Retrieval:
    1. Navigate to the AWS CloudFront console.
    2. Select the distribution of interest.
    3. Check the PriceClass setting in the distribution configuration.
  • Scan Schedule: This policy runs reactively based on resource changes and does not scan on a set schedule.

Triage​

  • Impact: Leaving the distribution in 'PriceClass_All' will lead to higher delivery costs.
  • Worsening Over Time: Costs will continue to be higher if not addressed.
  • Potential Remediation Downsides: Changing the pricing class may affect delivery latency or availability in some regions but should not cause service outages.

Act​

  1. Review the current PriceClass setting for the distribution.
  2. Consider switching to 'PriceClass_100' or 'PriceClass_200' to exclude more expensive edge locations.
  3. Save the updated configuration in the CloudFront console.

Reflect​

  • Review: If this alarm was not a good use of time, consider adjusting the policy thresholds.
  • Disable Policy: If constant changes in the pricing class are expected, disable this policy temporarily.
