Accelerate Your Business and Aim for the Cloud with Java and JRuby
1 like512 views
A core strength of the JVM is support for polyglot development. In fact, Java 7 includes performance improvements that will increase the use of popular Web languages on the JVM such as JavaScript, Ruby, and Python. Enterprises today are moving to the cloud to improve agility, cost, and scale. Ruby, together with the Rails framework, is one of the hottest languages in the cloud. At the same time, it's no secret that Java is the foundation of the enterprise. With JRuby, Java and Ruby run side-by-side to accelerate migration by leveraging existing infrastructure. This presentation reviews technology, best practices, and case studies of companies enjoying competitive advantage via the powerful combination of Java, Ruby, and the cloud.

- 21. "Using JRuby, we’ve saved hundreds to thousands of hours by leveraging existing infrastructure, monitoring tools, and developer experience, and we end up with 75% less code to manage than using Java." -Dylan Stamat, CTOJRuby Case Study21
- 22. "JRuby allows us to use the power of the Ruby language, build a smaller code base, and access Java libraries. We used JRuby to build a web application for the U.S. State Dept who wanted to modernize a 10 year old Java application.There was a lot of complex knowledge in the legacy code that would have been lost if we had to re-build it from scratch. With JRuby, we can take advantage of the speed of developing in Ruby and still access existing Java libraries for features like workflow, business logic, internationalization, and localization.” - David Bock, Principal ConsultantJRuby Case Study22
- 23. "JRuby has been a great help to LinkedIn with rapid application development by allowing us to leverage our existing Java libraries right in a Rails or Sinatra application. In one instance, JRuby saved nearly a week of development effort by not having to port a proprietary library over to native Ruby code. That’s a huge win for development velocity, code reuse and developer sanity.”-Jon Bettcher, Senior Software Engineer JRuby Case Study23
