Answer: Amazon S3 with cross-region replication
Amazon S3 supports cross-region replication, which allows you to replicate objects automatically from one S3 bucket to another S3 bucket in a different AWS region. This can be used to achieve data durability, availability, and disaster recovery across multiple regions. To configure it, you can enable cross-region replication on the source bucket and specify the destination bucket and replication rules. Amazon RDS with Multi-AZ deployment provides high availability and data durability within a single region, but it does not support cross-region replication. Amazon DynamoDB with global tables can be used to replicate data across multiple regions, but it is a NoSQL database service and may not be suitable for all use cases. Amazon Redshift with cross-region snapshot copy can be used to replicate data warehouse snapshots across regions, but it is a data warehouse service and may not be suitable for all use cases.
