An application currently reads and writes objects in a single Amazon S3 bucket. The company will deploy the application to a second AWS Region and wants the simplest solution with the least operational overhead to allow the application to operate across Regions. Which design meets these requirements?

The correct solution leverages S3 Multi-Region Access Points (MRAP) for seamless, low-latency access to S3 data across multiple AWS Regions. By creating a new S3 bucket in the second Region and configuring bidirectional S3 Cross-Region Replication (CRR), data is kept synchronized between both buckets. The MRAP then provides a single global endpoint that automatically routes requests to the nearest bucket, ensuring high availability and performance for applications deployed in both Regions. This approach minimizes operational overhead as the application doesn't need to manage regional endpoints or replication logic directly. Using CloudFront with Global Accelerator would provide global access but is primarily for caching and accelerating content delivery, not for active multi-region read/write operations to S3 with automatic routing based on application location. Configuring one-way CRR and having applications use local buckets would require the application to manage which bucket to write to and would not provide a single endpoint for both regions, increasing complexity. An S3 gateway endpoint is for accessing S3 from within a VPC and does not solve the multi-region access problem for applications.
