After reading a bit through it and i am wondering what the limitations are. I am a bit "scared" that deis talks about heroku so much and about HTTP. From the documentation it seems that the containers can ONLY use one port and that must be HTTP. Is that right? Also, the external storage is mentioned everywhere but not exactly what it is. I have read that Postgres is a database for the applications. What about plain files? Can my apps persist files on the external storage?

If this is only about pushing the next Go-based Todo web app to some servers, i'm disappointed... :(

Usecase: Is it possible to run mail servers on it?
