Automate on-premises image transfer to S3 with AWS DataSync
A company that develops consumer electronics with offices in Europe and Asia has 60 TB of software images stored on premises in Europe. The company wants to transfer the images to an Amazon S3 bucket in the ap-northeast-1 Region. New software images are created daily and must be encrypted in transit. The company needs a solution that does not require custom development to automatically transfer all existing and new software images to Amazon S3. What is the next step in the transfer process?

Community Insight
DataSync is a managed transfer service that moves data between on-premises storage and AWS storage on a schedule, and it uses TLS for the data in transit, so daily recurring transfers happen automatically once a task is configured.
A consumer electronics company has 60 TB of software images on premises in Europe that must reach an S3 bucket in ap-northeast-1. New images are created daily, the transfer must be encrypted in transit, and no custom development is permitted.
Writing a Site-to-Site VPN plus a custom S3 multipart upload script. That approach is feasible for connectivity but requires the company to build and maintain upload logic, which the requirement explicitly excludes, and a 60 TB transfer over an internet-bound VPN would be slow.

Expert Analysis
Why the Answer Is Correct
AWS DataSync is a managed service that automates and accelerates data movement between on-premises storage and Amazon S3 without any custom code. Deploying the DataSync agent in the on-premises environment and configuring a task that targets the ap-northeast-1 bucket handles the initial 60 TB transfer, and because the task is scheduled it also picks up each day's new images automatically, which satisfies the recurring requirement. DataSync encrypts data in transit with TLS, meeting the encryption requirement without any additional configuration from the company.Why the Other Options Are Wrong
B: Kinesis Data Firehose is a real-time streaming ingestion service for data sources such as logs and telemetry, and adding S3 Transfer Acceleration on top of it would only speed up long-distance transfers, it does not replace the missing transfer orchestration for on-premises files. C: A Snowball device is an offline physical shipping option best suited to petabyte-scale or poorly connected transfers, and it is a manual, one-time process that does not handle the daily recurring images, so it cannot meet the ongoing requirement. D: Transferring over a Site-to-Site VPN with the S3 API and multipart upload works technically, but writing and operating that upload logic is custom development, which the requirement rules out, and the throughput over an internet path is poor for 60 TB.Community Comment Notes
The community voted 100 to 0 for A, citing the AWS blog on synchronizing data to Amazon S3 with AWS DataSync and another on migrating hundreds of terabytes with DataSync, and one commenter explicitly noted that option D is feasible only if custom development were acceptable.Official Reference
