This is one of those things that I was talking about them sympathizing with.
It's unrealistic. If you're getting banned from github or a cloud provider maybe you should reconsider what you're doing.

Okay, but AWS isn't expensive as it is. If you build to the way these resources are meant to be built you can seriously minimize your costs.
I've seen plenty of lift and shifted apps get their costs dramatically reduced once redesigned in a "cloud native" architecture. The lift and shifted design was in the thousands of dollars a month. Rebuilding for AWS resources brought our costs to almost literally nothing on this same app. I'm talking $5,000 a month to $5 per month.
So I have a hard time following the premise that you'll do it cheaper with an on-prem or self-managed system.
