Lambda@Edge

Lambda@Edge is a technology that allows you to run code close to your website visitors by executing functions on servers within a content delivery network (CDN). This enables real-time customization and personalization of content, faster response times, and reduced load on your main servers. Essentially, it helps improve user experience by handling specific tasks—like modifying web pages, authenticating users, or filtering content—right at the edge of the network, minimizing delays and optimizing performance without needing to centralize all processing.
