Which solution will meet these requirements?
Deploy an Amazon FSx cluster for multiple application hosts to mount in the primary Region. Configure a second Amazon FSx deployment in the secondary Region. Configure replication from the Amazon FSx cluster in the primary Region to the Amazon FSx deployment in the secondary Region.
Deploy two Amazon S3 buckets, one in each Region. Enable S3 Versioning for each bucket. Enable S3 Replication Time Control (S3 RTC) to replicate objects to the secondary Region. Specify S3 Glacier Deep Archive as the storage class in the secondary Region.
Deploy two Amazon S3 buckets, one in each Region. Enable S3 Versioning for the bucket in the primary Region. Set up S3 Cross-Region Replication (CRR) from the primary Region to the secondary Region. Create an S3 event secondary bucket to invoke an AWS Lambda function that reviews each replicated object and specifies S3 Glacier Deep Archive as the storage class in the secondary Region.
Deploy an Amazon FSx multi-Region cluster. Configure the multi-Region cluster with object versioning. Mount the file system as ZFS with versioning support. Activate S3 archiving from Amazon FSx.
Explanations:
Amazon FSx does not support Cross-Region replication with a guaranteed SLA of 15 minutes for replication. Additionally, Amazon FSx is generally suited for file-based workloads rather than object storage with versioning and cost-efficient archival like S3 Glacier Deep Archive.
This option meets all requirements: S3 buckets with Versioning protect against overwrites, S3 Replication Time Control (RTC) guarantees a 15-minute replication SLA, and using S3 Glacier Deep Archive in the secondary Region provides cost-effective storage. The solution aligns with the 99.99% SLA requirement.
This setup does not meet the 15-minute replication SLA requirement. While S3 Cross-Region Replication provides replication, it does not guarantee the replication time without S3 RTC. Additionally, setting up Lambda to change storage classes is complex and adds operational overhead.
Amazon FSx multi-Region clusters do not support object versioning and guaranteed replication within 15 minutes. FSx clusters also do not natively support S3 Glacier Deep Archive storage, making this option both technically unfeasible and not cost-optimized as required in the secondary Region.
As far as I can tell, the answer is:
Deploy two Amazon S3 buckets, one in each Region. Enable S3 Versioning for each bucket. Enable S3 Replication Time Control (S3 RTC) to replicate objects to the secondary Region. Specify S3 Glacier Deep Archive as the storage class in the secondary Region.
