Answer 2

A. AWS Snowball

When planning on getting your data into the cloud as a part of an application migration or a data center shutdown, you will run into the hard limits of data transport. When your Internet speeds are not enough to keep up with your data migration plan, it’s time to consider AWS Snowball. The Snowball appliance allows you to move archives, data lakes, and whatever data you have at faster-than Internet speeds right into Amazon S3 buckets. From Amazon S3, data can be archived into Glacier or analyzed by other services such as AWS Redshift or EMR. This implementation guide will get you started with AWS Snowball’s quick, simple, and secure process for migrating large amounts of data into AWS.
