One-line summary
The classic offline-migration pattern: AWS ships a secured device, the customer loads and returns it, and AWS imports the data into cloud storage.
Use cases and flow
- The network is unavailable or unreliable, or moving terabytes or petabytes online would take too long.
- AWS ships the device → the customer copies and validates data → returns it → AWS imports the data and erases customer data from the device.
- Existing customers may also use supported devices for edge workloads in disconnected or constrained environments.
Current status
- Snowball Edge is no longer available to new customers, although legacy exam questions still use it as the offline physical-migration answer.
- New customers should evaluate DataSync for online movement, Data Transfer Terminal or partner offerings for physical transfer, and Outposts for edge computing.
Common distinctions
- DataSync moves data online; Direct Connect supplies a dedicated network path; Snowball Edge is a physical device.
- Physical transfer does not remove the need for encryption, chain of custody, and integrity validation.
Key takeaway
Exam: weak network plus very large data means Snowball Edge. Real project: verify current availability and alternatives first.
