I think the issue is cost. Heroku, which is itself on top Of AWS, is expensive exactly because it has to charge a significant premium over AWS to work (although it is still overpriced). That’s where Render.com and Fly will succeed, by running on their own hardware they can save significantly over running on AWS. I don’t think it’s possible to build a PAAS on top of AWS, the OP with the I/PAAC would though as they aren’t trying to add a business service layer.
