What should a solutions architect do to meet these requirements?
Migrate all the data to Amazon S3. Set up IAM authentication for users to access files.
Set up an Amazon S3 File Gateway. Mount the S3 File Gateway on the existing EC2 instances.
Extend the file share environment to Amazon FSx for Windows File Server with a Multi-AZ configuration. Migrate all the data to FSx for Windows File Server.
Extend the file share environment to Amazon Elastic File System (Amazon EFS) with a Multi-AZ configuration. Migrate all the data to Amazon EFS.
Explanations:
Migrating all data to Amazon S3 does not preserve the Windows file share access method and IAM authentication is not suitable for Windows file access.
An S3 File Gateway allows S3 access but may not fully support Windows file sharing requirements and does not provide a native Windows file share experience.
Amazon FSx for Windows File Server offers a fully managed Windows file system with Multi-AZ support, preserving the Windows file share access methods.
Amazon EFS is not designed specifically for Windows workloads and may not support the required Windows file share protocols as effectively as FSx.
