Question #1623
A company needs to migrate 8 PB of data to Amazon S3 within 5 weeks. The on-premises data center has a 400 Mbps internet uplink, which is shared with other applications. The company can allocate 75% of the bandwidth for this migration. Which solution will meet the deadline?
Use AWS DataSync to transfer the data to Amazon S3 with built-in integrity checks.
Transfer the data directly to Amazon S3 using a multi-threaded FTP client.
Run parallel AWS CLI sync commands to upload the data directly to Amazon S3.
Ship multiple AWS Snowball Edge devices to the data center, copy the data, and return them to AWS for upload to S3.
Explanation
The company needs to transfer 8 PB (8,000 TB) of data within 5 weeks. With 75% of a 400 Mbps uplink (300 Mbps or ~37.5 MB/s), transferring over the internet would only move ~113 TB in 5 weeks—far less than required. Options A, B, and C rely on internet transfers and cannot meet the deadline. AWS Snowball Edge devices bypass bandwidth limitations by physically transporting data. Each Snowball Edge Storage Optimized device holds up to 80 TB, requiring ~100 devices. AWS handles logistics in parallel, ensuring timely delivery. This approach avoids bandwidth bottlenecks and ensures data integrity, making D the only viable solution.
Key Points:
- Internet bandwidth is insufficient for large-scale transfers (8 PB).
- Snowball Edge devices are designed for petabyte-scale migrations.
- Parallel shipping and AWS-managed logistics ensure speed and reliability.
Answer
The correct answer is: D
