Correct answer: Use AWS Snowball..
Why this is the answer
AWS Snowball is the most suitable solution. With a 15 Mbps network and 70% utilization, the effective bandwidth is 10.5 Mbps. Transferring 20 TB (20,000,000 MB) at 10.5 Mbps (1.3125 MB/s) would take approximately 17,280,000 seconds or 200 days, far exceeding the 30-day deadline. Snowball physically ships data, bypassing network limitations for large datasets and tight deadlines. AWS DataSync, a secure VPN connection, and Amazon S3 Transfer Acceleration all rely on network bandwidth. Given the severe bandwidth constraint and the large data volume, none of these options would enable the data transfer within the 30-day timeframe.
