A company receives 10 TB of instrumentation data each day from several machines located at a single factory. The data consists of JSON files stored on a storage area network (SAN) in an on-premises data center located within the factory. The company wants to send this data to Amazon S3 where it can be accessed by several additional systems that provide critical near-real-time analytics. A secure transfer is important because the data is considered sensitive.
Which solution offers the MOST reliable data transfer?

A
AWS DataSync over public internet
B
AWS DataSync over AWS Direct Connect
C
AWS Database Migration Service (AWS DMS) over public internet
D
AWS Database Migration Service (AWS DMS) over AWS Direct Connect
Explanation:
Explanation
Correct Answer: B - AWS DataSync over AWS Direct Connect
Why this is the most reliable solution:
-
AWS DataSync vs AWS DMS:
- AWS DataSync is specifically designed for transferring large amounts of data between on-premises storage systems and AWS storage services (like Amazon S3). It's optimized for file-based data transfer, which matches the JSON files stored on the SAN.
- AWS Database Migration Service (DMS) is designed for migrating databases between different database engines, not for transferring files from SAN storage to S3.
-
Direct Connect vs Public Internet:
- AWS Direct Connect provides a dedicated, private network connection from on-premises to AWS, offering:
- Higher reliability and consistent network performance
- Lower latency
- Enhanced security (data doesn't traverse the public internet)
- Predictable bandwidth
- Public internet connections are less reliable, have variable performance, and expose sensitive data to potential security risks.
- AWS Direct Connect provides a dedicated, private network connection from on-premises to AWS, offering:
-
Requirements alignment:
- 10 TB daily: Large data volume requires reliable, high-throughput transfer
- JSON files on SAN: File-based data transfer (DataSync's specialty)
- Critical near-real-time analytics: Requires reliable, consistent data flow
- Sensitive data: Security is paramount (Direct Connect provides private connection)
Why other options are incorrect:
- A (DataSync over public internet): Less reliable and less secure than using Direct Connect
- C (DMS over public internet): Wrong tool for the job (DMS is for databases, not files) and uses less secure public internet
- D (DMS over Direct Connect): Wrong tool for the job, even though it uses the better network connection
Additional considerations:
- DataSync provides built-in encryption, data integrity validation, and incremental transfer capabilities
- Direct Connect provides 99.9% availability SLA for dedicated connections
- This combination ensures secure, reliable transfer of sensitive instrumentation data for near-real-time analytics
