What is the primary use case for AWS Snowball?

The primary use case for AWS Snowball is transporting large amounts of data to and from AWS. AWS Snowball is designed to help users transfer significant volumes of data efficiently and securely, particularly when transferring data over the internet is impractical due to time constraints or bandwidth limitations.

This service is particularly beneficial for organizations looking to migrate vast datasets to AWS as it provides a physical device that can be shipped to the customer's location, loaded with data, and sent back to AWS for upload into S3 or other services. This approach drastically reduces the time it would take to transfer large datasets over the network, which could take weeks or even months, depending on the data's size and the available bandwidth.

The other options do involve aspects of cloud computing, but they do not align with Snowball’s primary purpose. For instance, high-speed file sharing may imply transferring smaller sets of data efficiently online, while building cloud applications encompasses a broader range of services and tools not specific to data transport. Data encryption management involves securing data but does not capture the core functionality that Snowball offers in terms of physically moving data.
