A company has a Windows-based application that must be migrated to AWS. The application requires a shared Windows file system that is accessible from multiple Amazon EC2 Windows instances deployed across multiple Availability Zones. What should a solutions architect do to meet this requirement?

Amazon FSx for Windows File Server provides a fully managed, highly reliable, and scalable native Windows file system. It supports the Server Message Block (SMB) protocol, which is essential for Windows-based applications, and can be accessed from multiple EC2 instances across Availability Zones, fulfilling the shared file system requirement. AWS Storage Gateway in volume gateway mode provides block storage, not a shared file system accessible by multiple instances simultaneously. Amazon EFS is a shared file system, but it uses the Network File System (NFS) protocol, which is primarily for Linux-based instances and not natively supported by Windows for shared access. Amazon EBS volumes are block-level storage attached to a single EC2 instance at a time and cannot be simultaneously mounted by multiple instances for shared file access.
