Heroku allows users to run Ruby 2.0 on their platform. Users can specify Ruby 2.0 as the runtime in their Gemfile or use a custom buildpack. Heroku has already provided a sandbox for evaluating Ruby 2.0. The document demonstrates how to create a Ruby 2.0 app on Heroku by specifying the Ruby version and dependencies in the Gemfile, committing, and pushing to Heroku. Users are encouraged to try Ruby 2.0 on Heroku now and attend Heroku's Waza developer event in February 2013.
