Tuning JVM for a VM - lessons learned, directly from VMware

We already know about JVM internals and large-heap GC issues, but running JVM on top of another virtual environment posses its own set of challenges. Fortunately, Ben Corrie, from VMware, offered to help us understand the issues and show us how to best tune our JVM for this increasingly common deployment option.

The number of Java workloads running on virtualized infrastructure has been increasing exponentially over the last few years. Advancements in processors and hypervisor technology now make virtualizing Java a compelling proposition. However, there are still best practice provisos and considerations, particularly in the area of JVM memory management. This talk will present a lot of the innovation, practical insight, and lessons learned gained from the last year by a senior engineer from VMware who recently developed a Java "ballooning" solution called Elastic Memory for Java (EM4J)

As always, venue, food, drinks, and giveaways will be provided by our sponsors!

The rough agenda for the evening looks like this:

6:00-6:25pm: Arrive and mingle (food/drinks provided)
6:25-6:30pm: Announcements
6:30-8:00pm: Ben's presentation
8:00-8:15pm: Q&A, wrap-up, and giveaways

About Ben Corrie
Ben Corrie has been working on Java since 1998, where he began at IBM testing JDK 1.1.4. He progressed to working on the internals of IBM's Java Virtual Machine where he lead a project to develop industry-leading memory management technology for the JVM. He joined SpringSource as a consultant in 2008 and moved to California a year later to lead an effort to improve Java performance on vSphere.

    This was a fascinating talk. The speaker did a great job of balancing presentation and question/answer. Lots of good technical detail, presented at a good pace.

    @pudur ramaswamy: I think this is the link to the VI Java project page on Sourceforge:

    I think it may have been very good but the combination of sitting at the back and poor site acoustics caused me to miss critical points in the presentation. I'll have to review the slides/video to fill in the gaps once posted.

    Right. I just found out about that recently as well. We'll likely have to reschedule our event to a different date. I'll let you know.
