Using Lambda@Edge functions with origin failover

You can use Lambda@Edge functions with CloudFront distributions that you've set up with origin groups, for example, for origin failover that you configure to help ensure high availability. To use a Lambda function with an origin group, specify the function in an origin request or origin response trigger for an origin group when you create the cache behavior.
