Which storage solution will meet these requirements?
Use Amazon S3 for the application storage. Create an S3 bucket in the primary Region and an S3 bucket in the DR Region. Configure S3 Cross-Region Replication (CRR) from the primary Region to the DR Region.
Use Amazon Elastic Block Store (Amazon EBS) for the application storage. Create a backup plan in AWS Backup that creates snapshots of the EBS volumes that are in the primary Region and replicates the snapshots to the DR Region.
Use a Volume Gateway in AWS Storage Gateway for the application storage. Configure Cross-Region Replication (CRR) of the Volume Gateway from the primary Region to the DR Region.
Use Amazon FSx for NetApp ONTAP for the application storage. Create an FSx for ONTAP instance in the DR Region. Configure NetApp SnapMirror replication from the primary Region to the DR Region.
Explanations:
Amazon S3 is an object storage service and does not support SMB or NFS protocols natively. Thus, it cannot directly serve shared storage needs for Windows and Linux applications requiring SMB and NFS access. While S3 Cross-Region Replication can replicate data, it does not meet the specific protocol requirements for the applications.
Amazon Elastic Block Store (EBS) provides block storage that is primarily used for single EC2 instances and does not offer built-in cross-region replication for EBS volumes. Snapshots can be replicated, but EBS does not support SMB or NFS protocols directly for shared storage between multiple instances. Therefore, it does not meet the shared storage requirements of the applications.
AWS Storage Gateway Volume Gateway provides block storage that can be accessed via iSCSI but does not natively support SMB or NFS for cross-region replication. Cross-Region Replication is not a feature of Volume Gateway, making it unsuitable for the shared storage requirement between different application types and across regions.
Amazon FSx for NetApp ONTAP supports both SMB for Windows applications and NFS for Linux applications, making it suitable for shared storage needs. Additionally, NetApp SnapMirror provides efficient data replication across regions, fulfilling the requirement to replicate storage to the DR Region while allowing access via the required protocols.
I organize that the answer is:
Use Amazon FSx for NetApp ONTAP for the application storage. Create an FSx for ONTAP instance in the DR Region. Configure NetApp SnapMirror replication from the primary Region to the DR Region.
