Samples for use of Amazon CloudFront, including Lambda functions, and SDK usage examples.
This AWS Lambda function is written in Python and can be used to automatically update EC2 security group ingress rules when CloudFront IP ranges change.
By subscribing this function to the SNS topic AmazonIpSpaceChanged your security groups that are properly tagged will be updated accordingly.
For more information on ip-ranges.json, read the documentation on AWS IP Address Ranges.
