Although code deployment might not be as easy with Engine Yard as with <a href="http://www.infoworld.com/d/application-development/infoworld-review-heroku-cloud-application-platform-180342">Heroku</a>, the Engine Yard platform is dramatically more tunable. In fact, in many ways, Engine Yard is closer to an infrastructure as a service (IaaS) than a platform as a service (PaaS). Engine Yard provides a base infrastructure tuned to run Ruby applications, but the rest is up to you. Engine Yard does offer <a href="http://www.infoworld.com/d/application-development/torvaldss-git-the-it-technology-software-version-control-167799">Git integration</a>; however, deployment is not executed via a push, as in Heroku, but rather via Engine Yard's suite of tools and its extensive dashboard, which can sync with a Git repository.
