A company has multiple Microsoft Windows SMB file servers and Linux NFS file servers for file sharing in an on-premises environment. As part of the company's AWS migration plan, the company wants to…

Amazon FSx for NetApp ONTAP is a fully managed file storage service that natively supports multi-protocol access, allowing clients to access the same file system data over both SMB and NFS. It also provides high availability and redundancy across Availability Zones, directly meeting all specified requirements for a managed, protocol-sharing solution.

Creating and managing two Amazon EC2 instances for separate SMB and NFS file servers requires significant operational overhead for OS management, file server software, storage, and ensuring data consistency/redundancy, which does not meet the requirement for a *managed AWS storage service*.

Using Amazon FSx for NetApp ONTAP for SMB and Amazon FSx for Lustre for NFS would create two separate file systems, preventing data sharing between protocols and increasing management complexity. FSx for Lustre is also primarily designed for high-performance computing, not general-purpose multi-protocol file sharing.

Amazon S3 is object storage and does not natively support NFS or SMB protocols for direct file system access within AWS. While an Amazon S3 File Gateway can bridge on-premises access, it is not a managed file server solution directly within AWS for EC2 clients with multi-protocol support and sharing.
