A company runs multiple Windows workloads on AWS. The company's employees use Windows file shares that are hosted on two Amazon EC2 instances. The file shares synchronize data between themselves and maintain duplicate copies. The company wants a highly available and durable storage solution that preserves how users currently access the files.
What should a solutions architect do to meet these requirements?

A
Migrate all the data to Amazon S3. Set up IAM authentication for users to access files.
B
Set up an Amazon S3 File Gateway. Mount the S3 File Gateway on the existing EC2 instances.
C
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.
D
Extend the file share environment to Amazon Elastic File System (Amazon EFS) with a Multi-AZ configuration. Migrate all the data to Amazon EFS.

Explanation
Correct Answer: C
Amazon FSx for Windows File Server is the optimal solution because:
-
Native Windows Compatibility: FSx for Windows File Server provides fully managed Windows file servers that support the SMB protocol, Active Directory integration, and Windows file system semantics. This preserves how users currently access files.
-
High Availability: The Multi-AZ configuration ensures automatic failover to a standby file server in another Availability Zone if the primary fails, providing high availability.
-
Durability: FSx automatically replicates data within and across Availability Zones, providing durability.
-
Seamless Migration: The solution allows for extending the existing file share environment and migrating data while maintaining user access patterns.
Why other options are incorrect:
-
A (Amazon S3 with IAM): S3 is object storage, not file storage. It doesn't support Windows file shares or SMB protocol. Users would need to change how they access files.
-
B (S3 File Gateway): While File Gateway provides SMB access to S3, it's not a fully managed, highly available file system solution. It would still require managing EC2 instances and doesn't provide the same level of HA as FSx Multi-AZ.
-
D (Amazon EFS): EFS is designed for Linux workloads using NFS protocol, not Windows workloads. It doesn't support SMB protocol or Windows file system semantics.
Key Requirements Met:
- ✅ Highly available (Multi-AZ configuration)
- ✅ Durable storage
- ✅ Preserves current user access patterns (Windows file shares)
- ✅ Suitable for Windows workloads
