How can S3 Multi-Region Access Points and Cross-Region Replication support building a resilient, low latency, globally distributed storage architecture?
AdvancedAnswer
S3 Cross-Region Replication automatically and asynchronously copies objects from a bucket in one region to a bucket in another region, providing geographic redundancy and enabling lower latency access for users closer to the replica region, while S3 Multi-Region Access Points provide a single global endpoint that automatically routes requests to the closest or most appropriate underlying bucket across multiple regions, together simplifying the architecture needed to serve a globally distributed user base while maintaining strong data resilience.
