Deploy using the JVMs high performance while building your apps in the language you love. JRuby is a fast, scalable, and powerful JVM language with all the benefits of a traditional Ruby environment. See how to consolidate the many moving parts of an MRI-based Ruby deployment onto a single JVM process. Youll learn how to port a Rails application to JRuby, get it into production, and keep it running. JRuby deployments have fewer moving parts and consume less memory than traditional Ruby deployments, but to deploy your apps on the JVM, you need to learn some new approaches. This book introduces you to three JRuby deployment strategies that will give you the performance and scalability you need while letting you use the language you love. Youll start by porting an existing application to JRuby, preparing the app to take advantage of the JVM platform. Then youll use Vagrant and Puppet to build a virtual production environment so you have a stable, reproducible place to explore JRuby deployment. With your environment in place, youll experiment with simple JRuby deployment with Warbler as you package your Ruby web application into a single file you can deploy to a Java application server. Next youll set up the lightweight Trinidad web server to create a more flexible, modular deployment that fits more complex situations but still feels friendly and familiar to Ruby developers. Youll switch to powering your app with TorqueBox, an all-in-one JRuby environment that includes built-in support for messaging, scheduling, and daemons--perfect for handling the «big jobs.» Then, youll set up a continuous integration environment with Jenkins so you can deploy like the pros.
