Question

What is Lambda Edge and how it is different to Lambda? What are the new benefits if any with Lambda Edge?

Answer 1

Lambda@Edge is a feature of AWS Cloudfront that allows you to run your code across AWS locations globally, without managing about the servers, the response to end users can also be done at lowest network latency. All you need to do is upload your Node.js code to AWS Lambda and then configure the function to be triggered as response to AWS CloudFront requests. The code is therefore ready to be executed across AWS locations.
