        Unfortunately the audio on this goes to hell about 15 minutes in. Don't listen with the volume too loud or you'll be punished with really loud static blasts. Ironicly the static blasts only seem to occur when he says important things :P

        Great presentation, Randy.

        Have you checked out the nascent Design Patterns Project over at the Open Management Consortium?
        www.open-management.com/community/open_standard...

        The early efforts are around design patterns for automation, but many of the themes you touched on are well within the project's scope (of being a neutral repository for operations design patterns).

        Hi, Damon --

        Glad you liked the presentation.

        Thanks a lot for the pointer to the Design Patterns Project -- I hadn't known about it before. Looks like it is off to an encouraging start. I'll be interested to see how it evolves. It certainly would be valuable to have a repository for such patterns.

        hello randy. where can i download the presentation?
        it seems like you apply very well a federated database system(or virtual database)
        thanks in advance

        Hi, Mario --

        A pdf version is available from the QCon SF conference track "Architectures you've always wondered about" (qcon.infoq.com/sanfrancisco/tracks/show_track.j...). Here is a direct link: www.eos1.dk/qcon/sf2007/slides/public/RandyShou...

        You can certainly think of eBay's database strategy as federated, and we definitely virtualize the federated aspect to make the programming model simpler for the developers. "Sharding" is a related term which seems to be entering more common use. Whatever you call it, it has been critical to our ability to scale.

        One thing I will add is that the fact that we implement the virtualization logic inside the application server (as opposed to some intermediate tier) has made it easier to optimize connections and request routing without an additional network hop.

      • Fantastic presentation

        Thank you Randy for sharing this brilliant material with us (Note: I have only read the PDF). Obviously, a number of strategies only apply to the range of massive traffic that eBay has (otherwise they come at the price of a difficult maintenance). But, still, I believe the principles are fundamentally right, and should be applied to any potentially large web site.
