Engine Yard Announces General Availability of JRuby on Engine Yard Cloud

Empowers Java Developers Programming in Ruby to Innovate Faster and Scale Easily on the Engine Yard PaaS

SAN FRANCISCO – September 28, 2011 – Engine Yard, the leading Platform as a Service (PaaS), today announced the general availability of JRuby on Engine Yard Cloud, bringing the powerful combination of Java performance and Ruby agility to the Engine Yard PaaS. JRuby, a Java implementation of the Ruby programming language, is a popular open source package that enables Ruby applications to run on the Java Virtual Machine (JVM). JRuby allows Java developers to use Ruby to efficiently expand the capabilities of Java applications or create new applications that leverage existing Java software.

“We are thrilled to announce that customers can now use JRuby in Engine Yard Cloud and leverage the power of Java on the Engine Yard platform.” said Dr Nic Williams, VP of Technology at Engine Yard. “This is huge in that it is the first truly threaded implementation of Ruby to have full production support. Customers can get the performance benefits of real concurrency in an enterprise-grade environment. Engine Yard is the first platform to make available all stable, production-ready Ruby implementations, including JRuby, MRI, and Rubinius.”

JRuby is a powerful Ruby implementation that runs on the JVM and delivers all of the advantages of Ruby along with Java interoperability and access to the full range of Java platform functionality. Ruby applications running on JRuby benefit significantly from the JVM’s multi-threading and other performance strengths. For more details on the benefits Ruby can offer Java teams and how to get started with JRuby, developers are invited to download the quick-start guide at:

“JRuby provides unique productivity benefits to Java teams, including the ability to deploy Ruby code on the same servers, use the same libraries, and integrate with existing Java software that they are familiar with,” said Charles Nutter, co-lead of the JRuby team at Engine Yard. “Complementing the Engine Yard JRuby support offering, JRuby on Engine Yard Cloud enables businesses and developers to realize a greater ROI on their Java investments.”

Three of the JRuby open source project’s four core contributors work at Engine Yard, including Thomas Enebo, Charles Nutter and Nick Sieger. Engine Yard also sponsors the development of Trinidad and employs its primary developer, David Calavera. Trinidad is an application server designed to run Rack applications within Apache Tomcat, a lightweight Java web server and a key enabler for JRuby support.
