How do you host your production rails app?

I've been using AWS ECS (and adjacent services) and it was a bit of a learning curve/time pit even though I'm fairly familiar with AWS. But I also dug a little into the search traffic for this topic (hosting rails on aws) and it seems like almost no one is searching for information about this. I like the idea of Heroku but it also seems like the pricing is significantly higher so I veered away from it. Is hosting on the larger generic cloud service providers something that people do? How do you host your rails application for real traffic serving applications?
