However to the comment about "git push heroku master," someone that is an "early" programmer like myself finds that level of simplification helpful when I'm focusing on things like learning all the other things that could go wrong with my Rails Tutorial app.
That said, as I now am at the point of starting to work on projects that I hope to one day be public facing, I'm wondering if there are any recommendations for "Heroku-like" providers with a free tier that stays up 24/7 for super simple Rails and Sinatra apps, perhaps with a DB.
