Heroku is awesome for ruby development. If you're attempting node.js development, they do have a private beta (which I've tested), but is somewhat limited as I believe it uses an NGINX proxy so doing something like websockets with node.js (currently on Heroku) is not possible. git push master heroku is reason enough to give it a shot. Joyent may be another option...
