Internal if you have the IT resources & infrastructure for that to be reasonably painless. VPS if you need to access it from multiple public locations and don't want to expose an internal server, or if "internal server" isn't a thing where you work. Heroku if you don't know how to admin Linux or don't want to spend the time worrying about it.
