Heroku is great until you need to do something non-standard in your deployment, like compile node and configure a python virtualenv in the same deploy. Then you have to learn their Buildpack framework and that is a nightmare. It's a hugely complicated abstraction layer that, like one of the parent comments says, requires me to learn 200%. I have to learn all the steps to install/configure nodejs, then python, then how they decided to slap together a layer on top of it that made assumptions like you would only be doing one of these things.
