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?

AWS DataSync over public internet

AWS DataSync over AWS Direct Connect

AWS Database Migration Service (AWS DMS) over public internet

AWS Database Migration Service (AWS DMS) over AWS Direct Connect

Explanations:

AWS DataSync over public internet is less secure for sensitive data, as it does not use a private, dedicated connection.

AWS DataSync over AWS Direct Connect provides a secure, high-bandwidth, dedicated connection, ideal for large-scale, reliable data transfer.

AWS Database Migration Service (DMS) is primarily designed for database migrations, not large-scale file transfers like JSON files.

AWS Database Migration Service (DMS) is not optimized for transferring large amounts of JSON file data and is meant for database migrations.
