Phusion Passenger

Phusion Passenger (informally also known as mod_rails and mod_rack) is a free module for the Apache HTTP Server and nginx for deployment of Ruby applications, including those built using the Ruby on Rails framework. It is available as a Gem package and is supported on Unix-like operating systems. Phusion Passenger also supports arbitrary Ruby web applications that follow the Rack interface.

Phusion Passenger is the “preferred deployment setup” for Ruby on Rails applications, and has been recommended by the Ruby on Rails authors. In combination with Ruby Enterprise Edition, Phusion Passenger claims that it is capable of reducing Rails’s memory consumption by 33% as well as increasing its performance.
