Which solution will meet these requirements?
Use Amazon FSx for NetApp ONTAP for storage. Configure multi-protocol access.
Create two Amazon EC2 instances. Use one EC2 instance for Windows SMB file server access and one EC2 instance for Linux NFS file server access.
Use Amazon FSx for NetApp ONTAP for SMB access. Use Amazon FSx for Lustre for NFS access.
Use Amazon S3 storage. Access Amazon S3 through an Amazon S3 File Gateway.
Explanations:
Amazon FSx for NetApp ONTAP supports both NFS and SMB protocols with multi-protocol access, allowing seamless file sharing across different systems. It also provides redundancy at the Availability Zone level, meeting the requirements for high availability.
Creating two separate EC2 instances for SMB and NFS access does not provide a consolidated solution and lacks the managed service benefits. It also does not inherently offer redundancy at the Availability Zone level without additional configuration.
Using Amazon FSx for NetApp ONTAP for SMB and Amazon FSx for Lustre for NFS creates two distinct solutions that do not provide multi-protocol access in a single managed service, failing to meet the requirement for protocol sharing.
Amazon S3 storage accessed through an Amazon S3 File Gateway does not support native SMB or NFS protocols directly. This option also lacks redundancy at the Availability Zone level for file sharing needs in a seamless manner.
In my experience, the answer is:
Use Amazon FSx for NetApp ONTAP for storage. Configure multi-protocol access.
