feature

Amazon CloudFront now allows customers to use Origin Access Control (OAC) to secure Amazon S3 Multi-Region Access Points (MRAP) as origins. This enhancement simplifies protecting global content delivery, eliminating the prior need for custom Lambda@Edge functions to compute SigV4a authorization headers for MRAP. The native integration improves performance for cache-miss fills and enhances resilience for globally distributed users. This feature is generally available worldwide, excluding the CloudFront China region, and incurs no additional fees.

  • CloudFront OAC supports S3 Multi-Region Access Points

    CloudFront's Origin Access Control (OAC) now natively signs requests to S3 Multi-Region Access Points (MRAP) origins, allowing customers to restrict access to designated CloudFront distributions. This eliminates the previous requirement for custom Lambda@Edge functions to compute Asymmetric Signature Version 4 authorization headers. Customers benefit from faster cache-miss fills from the nearest region, enhanced security, and simplified configuration via CloudFront Console, SDK, CLI, or CloudFormation.
