Multi-Region Access Points in Amazon S3

Amazon S3 Multi-Region Access Points provide a global endpoint that applications can use to fulfill requests from S3 buckets that are located in multiple Amazon Web Services Regions. You can use Multi-Region Access Points to build multi-Region applications with the same architecture that's used in a single Region, and then run those applications anywhere in the world. Instead of sending requests over the congested public internet, Multi-Region Access Points provide built-in network resilience with acceleration of internet-based requests to Amazon S3. Application requests made to a Multi-Region Access Point global endpoint use Amazon Global Accelerator to automatically route over the Amazon global network to the closest-proximity S3 bucket with an active routing status.

When you create a Multi-Region Access Point, you specify a set of Amazon Web Services Regions where you want to store data to be served through that Multi-Region Access Point. You can use S3 Cross-Region Replication (CRR) to synchronize data among buckets in those Regions. You can then request or write data through the Multi-Region Access Point global endpoint. Amazon S3 automatically serves requests to the replicated dataset from the closest available Region. Multi-Region Access Points are also compatible with applications that are running in Amazon virtual private clouds (VPCs), including those that are using Amazon PrivateLink for Amazon S3.
