A company is running an SMB file server in its data center. The file server stores large files that are accessed frequently for the first few days after the files are created. After 7 days the files are rarely accessed. The total data size is increasing and is close to the company's total storage capacity. A solutions architect must increase the company's available storage space without losing low-latency access to the most recently accessed files. The solutions architect must also provide file lifecycle management to avoid future storage issues. Which solution will meet these requirements?

A
Use AWS DataSync to copy data that is older than 7 days from the SMB file server to AWS.
B
Create an Amazon S3 File Gateway to extend the company's storage space. Create an S3 Lifecycle policy to transition the data to S3 Glacier Deep Archive after 7 days.
C
Create an Amazon FSx for Windows File Server file system to extend the company's storage space.
D
Install a utility on each user's computer to access Amazon S3. Create an S3 Lifecycle policy to transition the data to S3 Glacier Flexible Retrieval after 7 days.

Explanation
Correct Answer: B
Why Option B is correct:
- Amazon S3 File Gateway provides a seamless way to extend on-premises storage to AWS while maintaining SMB protocol compatibility
- It offers low-latency access to frequently accessed files through local cache
- S3 Lifecycle policies automatically transition older data to cost-effective storage tiers
- S3 Glacier Deep Archive is appropriate for data rarely accessed after 7 days
- This solution addresses both immediate storage capacity issues and future lifecycle management
Why other options are incorrect:
A: AWS DataSync only copies data but doesn't provide ongoing storage extension or low-latency access to recent files. It's a one-time migration tool, not a storage extension solution.
C: Amazon FSx for Windows File Server would require migrating all data to AWS, which doesn't extend existing on-premises storage but replaces it. This doesn't solve the immediate capacity issue without significant migration effort.
D: Installing utilities on each user's computer is not scalable, doesn't maintain SMB protocol compatibility, and doesn't provide the seamless storage extension needed. Users would need to change their access patterns.
Key AWS Services Used:
- Amazon S3 File Gateway: Hybrid cloud storage solution that presents S3 as a file share
- S3 Lifecycle Policies: Automates data tiering to optimize costs
- S3 Glacier Deep Archive: Lowest-cost storage for rarely accessed data
This solution meets all requirements: extends storage capacity, maintains low-latency access to recent files, and provides automated lifecycle management.
