Data Ingestion and Transformation

A data engineer must securely move 5 TB of data from an on-premises data center to an Amazon S3 bucket. About 5% of the data changes daily, and those updates must be regularly propagated to the S3 bucket. The data contains files in multiple formats. The data engineer must automate the transfer and schedule it to run periodically.

Which AWS service should the data engineer use to transfer the data in the MOST operationally efficient manner?

  • A AWS DataSync
  • B AWS Glue
  • C AWS Direct Connect
  • D Amazon S3 Transfer Acceleration
Explanation

AWS DataSync securely transfers file and object data between on-premises storage and Amazon S3. It supports scheduled recurring tasks and incremental synchronization, making it suitable for an initial 5 TB transfer followed by regular transfers of the changed data without maintaining custom transfer scripts or infrastructure.
