Summary

Added Amazon ElastiCache to architecture components, modified AWS WAF role classification, updated log rotation details, and added ElastiCache section

Security assessment

While adding ElastiCache improves performance through caching, there's no explicit security configuration mentioned. The AWS WAF role change from 'Core' to 'Supporting' is a classification adjustment without security implications. Log rotation frequency update is operational rather than security-focused.

-DataSync is configurated to periodically move rotated log files from each Prebid Server container’s EFS location to an equivalent location in the `DataSyncLogsBucket` S3 bucket. After each file is copied to S3 and verified, it is removed from the EFS file system through a clean-up Lambda function. Essentially, only actively written log files are retained on the EFS file system until the Prebid Server process closes it, rotates it, and starts a new file. Rotated log files are migrated with DataSync. Runtime logs are rotated every 24 hours or when reaching 100 MB. Metrics logs are rotated every one hour or when reaching 100 MB.
