A company has a business system that generates hundreds of reports each day. The business system saves the reports to a network share in CSV format. The company needs to store this data in the AWS Cloud in near-real time for analysis.
Which solution will meet these requirements with the LEAST administrative overhead?

A
Use AWS DataSync to transfer the files to Amazon S3. Create a scheduled task that runs at the end of each day.
B
Create an Amazon S3 File Gateway. Update the business system to use a new network share from the S3 File Gateway.
C
Use AWS DataSync to transfer the files to Amazon S3. Create an application that uses the DataSync API in the automation workflow.
D
Deploy an AWS Transfer for SFTP endpoint. Create a script that checks for new files on the network share and uploads the new files by using SFTP.

Explanation
Option B (Amazon S3 File Gateway) is the correct answer because it provides the LEAST administrative overhead while meeting the near-real time requirement.
Analysis of each option:
Option A: Using AWS DataSync with a scheduled daily task
- ❌ Does NOT meet "near-real time" requirement (runs only at end of day)
- ❌ Requires manual scheduling and monitoring
- ❌ Higher administrative overhead than File Gateway
Option B: Amazon S3 File Gateway
- ✅ Minimal administrative overhead - File Gateway appears as a network share to the business system
- ✅ Near-real time - Files are automatically synced to S3 as they're written
- ✅ No application changes needed - Business system continues using network share
- ✅ Automatic synchronization - No manual scripts or scheduling required
Option C: AWS DataSync with custom API application
- ❌ High administrative overhead - Requires developing and maintaining custom application
- ❌ Complex integration with DataSync API
- ❌ Error handling and monitoring must be implemented
Option D: AWS Transfer for SFTP with custom script
- ❌ High administrative overhead - Requires developing and maintaining custom script
- ❌ Script must handle file checking, uploads, error handling
- ❌ Requires SFTP endpoint management
Why S3 File Gateway is optimal:
- Seamless integration - Appears as standard network file share (NFS or SMB)
- Automatic sync - Files written to the gateway are automatically uploaded to S3
- No application changes - Business system continues using existing network share interface
- Managed service - AWS handles scaling, availability, and maintenance
- Cost-effective - Pay only for storage used and data transfer
This solution eliminates the need for custom scripts, scheduled tasks, or application modifications while providing near-real time data availability in S3 for analysis.
