What extension of AWS Lambda allows code to be run at Amazon CloudFront edge locations?

Lambda@Edge is an extension of AWS Lambda that enables running code in response to events generated by Amazon CloudFront. This service allows developers to execute their functions at the edge locations close to the end-users, which significantly reduces latency and improves performance. By running code at the locations where requests are made, Lambda@Edge allows for dynamic content generation, execution of custom authentication, A/B testing, and other custom logic before the content reaches the user.

Lambda@Edge operates in conjunction with CloudFront, enabling developers to associate their Lambda functions with CloudFront event triggers such as viewer requests, origin requests, viewer responses, and origin responses. This integration allows for a seamless way to enhance the CDN capabilities of CloudFront while maintaining performance and security.

The other options pertain to different services or functionalities within AWS. AWS Lambda Edge Function is not a recognized name for any service; AWS Global Accelerator is a service designed to improve the availability and performance of applications with users geographically dispersed, while AWS CloudFront Functions provides lightweight serverless functions that run in response to CloudFront events but lacks the depth of capability provided by Lambda@Edge.
