Amazon S3 Multi-Region Access Points now support datasets that are replicated across multiple AWS accounts. Cross-account Multi-Region Access Points simplify object storage access for applications that span both AWS Regions and accounts, avoiding the need for complex request routing logic in your applications. They provide a single global endpoint for your multi-region applications, and dynamically route S3 requests based on policies that you define. This helps you to more easily implement multi-region resilience, latency-based routing, and active-passive failover, even when data is stored in multiple accounts.

Many customers use S3 Replication to replicate data to a bucket in a different AWS account, providing additional protection against accidental or unauthorized data deletion. S3 Multi-Region Access Points now support these multi-account configurations. To get started, first set up cross-account S3 Replication. This will automatically maintain a replica of your data in one or more AWS Regions. Second, create a Multi-Region Access Point. The easiest way to do this is through the S3 console, which provides a step-by-step setup process, as well as an overview of your replication configuration and metrics. Finally, update the bucket policy for any bucket that is in a different AWS Account than your Multi-Region Access Point to allow retrieval requests.

S3 Multi-Region Access Points are supported in 17 AWS Regions. You can get started using the AWS CLI, API, AWS SDK, or AWS Management Console. For pricing information, visit Amazon S3 pricing. To learn more about S3 Multi-Region Access Points, visit the feature page or S3 FAQs.
