Lambda-at-Edge

Lambda@Edge allows you to run your own business logic as part of the CloudFront request flow. You can intercept all requests that arrive at CloudFront, all connections to the origin and the responses from the origin and to the client. Lambda@Edge functions come with a series of constraints that make them different from regular Lambda functions, but also a lot of commonalities. One of these is the concurrency quota, which you should check before a production deployment. ...

Lambda@Edge functions are executed in multiple regions around the world, but which ones exactly? In this post we’ll find out together, which will enable us to pre-create log groups and other resources for them.
