Given that you've worked in python, I think Django is a very easy framework choice here. If that weren't the case, I'd say it's just a "pick one" out of Rails/Django/Node (or some other JS framework, I'm not overly familiar with them). I'd go Heroku if you don't have much linux experience, or Digital Ocean if you don't mind setting up & maintaining a machine. AWS is fine as well, I'm sure, I just don't have any experience with it personally.
