Disaster Recovery

AWS CloudFront is a content distribution network. It allows for edge location spread around the world to cache content so that the original source only needs to be consulted after a certain amount of time has expired. CloudFront is a global AWS service and has the ability to serve files from an S3 bucket. It also can be configured to have a primary bucket and a backup bucket in case the primary is not available.

Create two S3 buckets in two different regions and then create a CloudFront distribution and create an Origin Group with both buckets and use that as the origin for the CloudFront distribution.
