OSGi at LinkedIn (EclipseCon 2009)

My presentation about Building LinkedIn’s Next Generation Architecture with OSGi is live on the EclipseCon web site (slides + audio). Here is the abstract:

Over the course of the last 5 years, LinkedIn has been built using relatively simple technologies: front end web applications (tomcat/servlet/jsp), backend services (jetty/spring remoting), databases, replication, jms. Although the web site was scaling adequately, LinkedIn had some big challenges to overcome:

  • a growing engineering team working on a monolithic code base (albeit modular)
  • a growing product team wanting more and more features, faster
  • a growing operations team deploying more and more servers
  • and more...

    • In March of 2008, a group of Senior Engineers started a project to explore the best available technologies which could help in building the next generation of the architecture that would address those challenges. The new architecture involved using OSGI/Spring DM as the foundation because it had the right properties we were interested in. The code was migrated to a more modular paradigm using binary consumption.

    This session will demonstrate how we integrated OSGi, the pros and cons of the changes, the pain points as well as the migration strategy.

    Hi Yan, Did you try using Janino on the fly compiler ? I am actually using it to compile on the fly Java code, But was wondering if you had a look on it and specially on how to solve dependencies to other Jar packages when compiling. And when classes are compiled how to package it in an OSGi Jar so another bundle can start it. Or maybe I should use maven-plugin to compile on the fly in OSGi ? Regrads, charbel

    Hi Charbel. No I have not tried Janino at all. I actually have never heard of it. To my knowledge Jasper supports OSGi so you may want to give this a try ? Yan
