https://aws.amazon.com/polly/ We launched https://aws.amazon.com/blogs/aws/s3-multi-region-access-points-accelerate-performance-availability/ to give you a global endpoint that spans S3 buckets in multiple AWS Regions. With S3 Multi-Region Access Points, you can build multi-region applications with the same simple architecture used in a single Region.
In the event that connectivity between a client and a bucket in a particular Region is lost, the Multi-Region Access Point will automatically route all traffic to the closest bucket (synchronized via S3 Replication) in another Region.
Buckets in active Regions receive traffic (GET, PUT, and other requests) from the Multi-Region Access Point, buckets in passive Regions don’t. Amazon S3 Cross-Region Replication operates regardless of the active or passive status of a Region with respect to a particular Multi-Region Access Point.
