When working on my small home project on Symfony2, I needed to deploy it on staging for testing API from the outside. Sure, you need some hosting for this purpose: either have it already or buy it. Yet there is an alternative — the cloud services where you can host your site for free but with limited resources. There are a lot of such services now and they are competing with each other. Somehow I decided to try Heroku. I heard about it a long time ago and at that point it crossed my mind. I didn’t look on other services, this time I just wanted to try my luck with Heroku. Fortunately, Heroku still has a free web hosting option so I started to search all the information needed for Symfony2 application deployment.
