Absolutely. My setup is, as stated, a dev instance. We have a substantially larger prod setup, but I can't get into the details about production scale on a public forum. That said, even the dev instance is moving a substantial amount of data; nothing like 800GB/day, but within an order of magnitude. And yes, bandwidth costs can be brutal, especially if you try to build a hybrid solution that uses heavy services that live outside of AWS. That said, the above comment didn't get into enough detail to get an accurate read on their bandwidth or CPU/Memory/Storage utilization, but if they can run it in a lab for $5/mo (which I doubt, since that barely covers power), then it can't be much, so I think it's fair to assume it's at least back-of-the-napkin similar scale.
