A company receives 10 TB of JSON instrumentation data per day from machines at a factory. The data is stored on a SAN in the on-premises factory data center. The company wants to send this data securely and reliably to Amazon S3 for near-real-time analytics. Which solution provides the MOST reliable data transfer?

AWS DataSync over AWS Direct Connect is the most reliable solution. DataSync is specifically designed for large-scale, online data transfers to and from S3, offering features like automatic recovery, encryption, and data integrity validation. AWS Direct Connect provides a dedicated, private network connection between your on-premises data center and AWS, ensuring consistent network performance and enhanced security compared to the public internet. AWS DMS is designed for database migrations, not for transferring large volumes of file-based instrumentation data. While DMS can transfer data, it's not optimized for this use case and would be less efficient
