Which solution will meet these requirements with the LEAST operational overhead?
Set up an Amazon CloudFront distribution with the S3 bucket as an origin. Deploy the application to a second Region Modify the application to use the CloudFront distribution. Use AWS Global Accelerator to access the data in the S3 bucket.
Create a new S3 bucket in a second Region. Set up bidirectional S3 Cross-Region Replication (CRR) between the original S3 bucket and the new S3 bucket. Configure an S3 Multi-Region Access Point that uses both S3 buckets. Deploy a modified application to both Regions.
Create a new S3 bucket in a second Region Deploy the application in the second Region. Configure the application to use the new S3 bucket. Set up S3 Cross-Region Replication (CRR) from the original S3 bucket to the new S3 bucket.
Set up an S3 gateway endpoint with the S3 bucket as an origin. Deploy the application to a second Region. Modify the application to use the new S3 gateway endpoint. Use S3 Intelligent-Tiering on the S3 bucket.
Explanations:
While using CloudFront could enhance performance by caching objects, it does not address the need for deploying the application across two regions. AWS Global Accelerator also does not directly assist with data storage across regions. This option would not fully meet the requirements of having the application effectively read/write from a replicated data store across regions.
This option sets up bidirectional S3 Cross-Region Replication (CRR), ensuring that objects written to either bucket are replicated to the other. By using an S3 Multi-Region Access Point, the application can access both buckets seamlessly with minimal operational overhead, thus fulfilling the requirement for deploying in two AWS regions efficiently.
This option creates a new S3 bucket in the second region and sets up S3 Cross-Region Replication (CRR) from the original bucket to the new one. However, it lacks a mechanism for ensuring the application can seamlessly access both buckets without additional complexity, making it less efficient than option B.
Setting up an S3 gateway endpoint and using S3 Intelligent-Tiering does not directly support multi-region deployments or replication of data. It mainly focuses on optimizing costs for object storage and does not fulfill the requirement for having a replicated data store in multiple regions.
