Which solution meets these requirements?
Use Amazon FSx for Windows File Server for the Windows instances. Use Amazon Elastic File System (Amazon EFS) with Max I/O performance mode for the Linux instances.
Use Amazon FSx for Windows File Server for the Windows instances. Use Amazon FSx for Lustre for the Linux instances. Link both Amazon FSx file systems to the same Amazon S3 bucket.
Use Amazon Elastic File System (Amazon EFS) with General Purpose performance mode for the Windows instances and the Linux instances
Use Amazon FSx for Windows File Server for the Windows instances and the Linux instances.
Explanations:
Amazon FSx for Windows File Server and Amazon EFS cannot be used together in a unified manner, as they don’t support cross-platform mounts directly or sharing between Windows and Linux.
Amazon FSx for Windows and FSx for Lustre are different file systems; linking both to an S3 bucket does not provide a centralized file system accessible by both Windows and Linux tools.
Amazon EFS does not natively support mounting on Windows instances, so it cannot provide a shared file system for both Windows and Linux instances.
Amazon FSx for Windows File Server supports SMB protocol, which allows it to be mounted on both Windows and Linux instances, making it suitable for cross-platform file sharing needs.
I scheme that the answer is:
Use Amazon FSx for Windows File Server for the Windows instances and the Linux instances.
