Forum: Rails deployment Best and easiest way to deploy a RoR application

Hi Folks,

I have heard about several tools for deployment, and I'm really
confused, could you guys explain what's all this new vocabulary means  ?
1 - Heroku
2 - Engine Yard
3 - Phusion Passenger
4 - Capistrano.

All these are tools for deployment,  if so which one is the easiest
and/or the best ? Do I need to be on a particular source versionning
(SVN, GIT etc...) to use them ?

Regards
