JRuby is built on Java - so it can make use of Java Web Start to make it easy to deploy JRuby apps. This article walks through the necessary steps for releasing a JRuby app with Java Web Start, including: how to handle signing, setting JRuby parameters and a look at using JRuby 1.1's coming AheadOfTime (AOT) compilation feature.
In a JavaOne presentation, Sun Microsystems’ Tony Printezis provided more details on Garbage First, a replacement for the CMS garbage collector particularly targeted at long running server applications.
Phusion Passenger/mod_rails makes deployment of Rails apps simple. The Apache configuration is handled by a script and re-deployment is a single 'touch' away. We talked to the creators of Phusion Passenger who also experiment with a modified Ruby Garbage Collector to share memory across address space borders.
'Release It!: Design and Deploy Production-Ready Software' by Michael Nygard, which is nominated for a 2008 Jolt Award, discusses what it takes to make production-ready software and explains how this differs from feature-complete software. InfoQ spoke with Nygard about the areas that the book covers and some questions around how the book's philosophy fits in with concepts such as Agile.
Finding performance bottlenecks can be a difficult task and it can get even more difficult as our applications grow in size. The Box is a methodology tool that focuses us efforts to improve performance.If you want to be consistent and predictable, getting rid of the guessing is a must.
Adrian Colyer goes in-depth on OSGi, its uses, future impact on the industry, and how Spring will make development with OSGi easier. Adrian talks about how OSGi may change the definition of an application server and JSR 277 vs. OSGi. According to Adrian, OSGi is going to change the deployment and run time model for enterprise applications.
InfoQ has an exclusive chat with one of the original gurus of Rails deployment: Ezra Zygmuntowicz. We discuss his current venture, EngineYard, and the future of Rails. His book on Rails Deployment is due from Pragmatic Programmers in June 2007.
OSGi is being adopted in an increasing number of projects. The spec provides a common model for writing and deploying apps to local or remote computers in modularized form. Instead of creating monolithic app, the OSGi spec allows the collaboration of many small components. This pres shows you why a spec like OSGi is crucial, what it really encompasses, and what the future developments will be.
When we move to distributed architectures for scalability and/or fault-tolerance reasons we are also introducing additional complexities. Amazon CTO Werner Vogels dives into the different parameters that play in the tension between availability and consistency and presents a generalized model that we can use to reason about the trade-offs between different solutions.
