Scaling with Terracotta

I recently had the pleasure of chatting with Alex Miller, who is a respected Java concurrency and scalability enthusiast (and fellow NFJS speaker) who works on Terracotta, an open source, Java-based clustering system. In this JavaWorld sponsored talk, Alex demystifies Terracotta, explaining the programming magic that enables enterprise customers to run 50 to 100 JVMs on a single application server instance. Alex also talks about Terracotta’s “sweet spot” — storing session data off of the database — and Terracotta 3.0, which promises new features that he says will eliminate certain scalability barriers.
