A company is hosting an application on AWS that currently reads and writes data objects stored in a single Amazon S3 bucket. To enhance the application's availability and performance, the company needs to deploy the application across two AWS Regions. What is the most efficient solution that minimizes operational overhead to achieve this?
Explanation:
Option B is the correct answer. It requires setting up a new S3 bucket in a second AWS Region, configuring bidirectional S3 Cross-Region Replication (CRR) between the original and new S3 buckets, and using an S3 Multi-Region Access Point that includes both S3 buckets. This solution ensures data redundancy and availability across regions and provides a global endpoint to access the data, which simplifies deployment and minimizes operational overhead. Option C, while possible, does not provide a bidirectional setup, which could lead to data inconsistency. Options A and D involve more complex configurations that do not directly address the requirement of minimizing operational overhead.
