A company has 150 TB of archived image data on-premises that must be moved to AWS within a month. The current network allows up to 100 Mbps uploads and only during the night. What is the MOST cost-effective way to transfer the data and meet the deadline?

The most cost-effective solution is to use multiple AWS Snowball devices. With 150 TB of data and a 100 Mbps upload speed, it would take approximately 138 days to transfer the data over the network, exceeding the one-month deadline. AWS Snowball devices are designed for large-scale data transfers (up to 80 TB per device) and are much more cost-effective than Snowmobile for this volume. AWS Snowmobile is typically used for exabyte-scale transfers (100 PB or more). S3 Transfer Acceleration would still be limited by the slow network speed, and a VPN with an S3 VPC endpoint doesn't address the bandwidth limitation for such a large data transfer.
