Amazon Web Services announced that, from October 2026, CloudFront can use Lambda Web Functions directly as an origin, enabling applications to benefit from TLS termination at edge locations, caching, and custom domains without code modifications. The integration includes Origin Access Control (OAC), restricting direct access to Lambda Web Functions and offering enhanced protection against network-layer DDoS attacks and compatibility with AWS Web Application Firewall for application-layer security.
This setup maintains authentication integrity by preserving original credentials in user-authenticated applications, ensuring seamless sign-in flows. CloudFront’s global edge network provision supports this feature worldwide, except for the CloudFront China region, facilitating developers’ configurations via multiple AWS interfaces without additional fees.
