From JRuby Conf 2012. This talk will help you bridge the gap between enjoying JRuby, and using it in the real world. JRuby can simplify your deployment architecture, while making your application more reliable, scalable, and easier to manage. You'll quickly see the benefits, but it will require a new technology stack.
There are three deployment strategies that can be used with any Rack-based JRuby application, and this talk will provide an overview of each of them. We'll also discuss the technologies that make them possible, and when it's appropriate to use each strategy. You'll learn how the Warbler gem can be used to create an web application archive file. Then we'll discuss how the light-weight Trinidad web server can be used to create a flexible, modular deployment that still feels friendly and familiar. Finally, you'll learn how to power an application with TorqueBox, an all-in-one environment that includes built-in support for messaging, scheduling and daemons.
