What should a solutions architect do to accomplish this?
Configure a volume using Amazon Elastic File System (Amazon EFS). Mount the EFS volume to each Windows instance.
Configure AWS Storage Gateway in Volume Gateway mode. Mount the volume to each Windows instance.
Configure Amazon FSx for Windows File Server. Mount the Amazon FSx volume to each Windows instance.
Configure an Amazon Elastic Block Store (Amazon EBS) volume with the required size. Attach each EC2 instance to the volume. Mount the file system within the volume to each Windows instance.
Explanations:
Amazon EFS is not natively supported on Windows for shared access. It’s primarily designed for Linux-based workloads.
AWS Storage Gateway in Volume Gateway mode does not provide a shared file system directly accessible by multiple EC2 instances in the way required.
Amazon FSx for Windows File Server is specifically designed for Windows applications and provides a shared file system that can be mounted by multiple EC2 Windows instances.
Amazon EBS volumes can only be attached to one EC2 instance at a time, making them unsuitable for shared access among multiple instances.
I think the answer is:
Configure Amazon FSx for Windows File Server. Mount the Amazon FSx volume to each Windows instance.
