 Ruby on Rails is a rapid development web framework that allows web designers and developers to implement dynamic fully featured web applications. This guide deploys Rails applications using the Phusion Passenger or `mod_rails` method. Passenger allows you to embed Rails apps directly in Apache applications without needing to worry about FastCGI or complex web server proxies.
