A company needs a one-time migration of an on-premises 60 TB MySQL database to Amazon Aurora MySQL in us-east-1. The current internet connection is low bandwidth and transferring the data over the internet would take about one month. The company needs the fastest possible migration. Which option will migrate the database in the least amount of time?

Correct answer: Order an AWS Snowball Edge device. Copy the database files onto the Snowball Edge using its S3-compatible interface and import them into an Amazon S3 bucket. Use AWS Database Migration Service (AWS DMS) to migrate the data from Amazon S3 into Aurora MySQL..
Why this is the answer
For a 60 TB database with a low-bandwidth internet connection, transferring data over the internet (even with Direct Connect or DataSync) would be too slow. AWS Snowball Edge is designed for large-scale data transfers where network bandwidth is a bottleneck. By physically shipping the data, it bypasses network limitations, making it the fastest option. The Snowball Edge's S3-compatible interface allows direct copying of database files. Once in S3, AWS DMS can efficiently migrate the data to Aurora MySQL. The other options are less efficient: Direct Connect, while faster than the internet, still relies on network bandwidth, which would be insufficient for 60 TB in a short timeframe. DataSync over a low-bandwidth internet connection would still be too slow for 60 TB. AWS Application Migration Service is for server migration, not database migration from S3. An AWS Snowball (not Snowball Edge) is also a good option for large data transfer, but the "S3 adapter" is not the primary method for loading database files, and AWS Application Migration Service is not the correct tool for migrating data from S3 to Aurora MySQL. Snowball Edge offers more compute and storage capabilities suitable for larger, more complex transfers.
