The python/django experience on dotCloud was really rather nice, actually. Perhaps much of that sympathy was coming from people were comparing Rails/Heroku with Rails/dotCloud, where Heroku has a rather big head start, but Django/dotCloud was the first easy, pipelineable deployment experience I had ever found despite having already tried all the early competition. It probably wouldn't have taken long for a Python-centric competitor to leapfrog them, but by the time they had, dotCloud was basically all in on the Docker experience, which was transformative.
