Amazon expanded S3 server access log delivery to Amazon CloudWatch Logs beyond commercial regions to also include AWS GovCloud (US), European Sovereign Cloud, and China Regions. This enables real-time querying, alarm setting, and integration with operational data for enhanced access pattern monitoring.

Delivering logs to CloudWatch supports encryption with AWS KMS keys and complements existing S3 bucket delivery, offering more flexible options for security auditing, incident investigation, and traffic analysis across global regions where S3 is available.
