A company needs to transfer 600 TB of data from an on-premises NAS to AWS within 2 weeks. The data is sensitive and must be encrypted in transit. The company’s internet upload speed is 100 Mbps. Which solution meets these requirements MOST cost-effectively?

Transferring 600 TB in two weeks with a 100 Mbps upload speed is infeasible. 100 Mbps would take approximately 550 days to transfer 600 TB. AWS Snowball Edge Storage Optimized devices are designed for large-scale data migrations (petabytes) where internet connectivity is limited or slow. They are shipped to your location, data is loaded onto them, and then they are shipped back to AWS for direct upload to S3, ensuring encryption in transit and at rest. This method is significantly faster and more cost-effective for this volume and timeframe than network-based transfers. Using Amazon S3 multipart upload over HTTPS with a 100 Mbps connection would be too slow. A VPN connection with 100 Mbps would also be too slow. AWS Direct Connect at 10 Gbps would provide the necessary bandwidth, but setting it up within two weeks is often not feasible, and it would be a significantly more expensive solution for a one-time data transfer compared to Snowball Edge.
