I would guess the real use case is: you considered becoming a Snowmobile customer but that's too heavy-duty and you need something for smaller amounts of data. Or you are a Snowmobile customer but sometimes you don't need to back up the truck for a relatively modest-in-size update.

So AWS made this.

Now they have an offering for you & everyone like you, that they can pitch to CxO execs, especially those who came from Snowmobile-using companies.
