https://www.dotcloud.com/ https://www.dotcloud.com/ does all three (Node, PHP and Ruby) along with many others. You can set up different instances, have them access the same database as well. When I was in their beta program when they first started out they also gave you shell access to the machine so you could see what was being deployed, and run arbitrary commands (perfect for having an Python app that required running paste for upgrading the DB to the latest version). In my experience with them I had absolutely no issues, it was fast to configure and set up and their command line tools were fantastic. It used git if you wanted it to, or could use any arbitrary directory and upload the contents. Not only that but you could modify the nginx config file to change redirects and set static directories that shouldn't be handled by WSGI so that you could take a load off the Python app from serving up requests for static content. I haven't used dotCloud in over 8+ months now, if not longer, their pricing just didn't make sense for me, and I found it cheaper with all the sites I host to just go with a single dedicated server rather than use their services so maybe a lot has changed, but they sound like what you need.
