Correct answer: Order an AWS Snowball Edge Storage Optimized device. Use AWS Database Migration Service (AWS DMS) with AWS Schema Conversion Tool (AWS SCT) to migrate the database with replication of ongoing changes. Send the Snowball Edge device to AWS to finish the migration and continue the ongoing replication..
Why this is the answer
The correct option leverages AWS Snowball Edge Storage Optimized for the initial bulk data transfer of the 20 TB MySQL database. This is cost-effective for large datasets where internet transfer would be slow and expensive. AWS DMS with AWS SCT ensures minimal downtime by handling schema conversion and continuous replication of changes during and after the physical transfer, making it suitable for a 2-week deadline.
Snowmobile is overkill and significantly more expensive for a 20 TB database; it's designed for petabyte-scale migrations. Snowball Edge Compute Optimized with GPU is not necessary as the primary requirement is storage and data transfer, not compute for the migration itself. A 1 GB Direct Connect connection might be too slow for a 20
