TechCast #47 – Jonas Boner on the Akka framework, Scala, and highly scalable applications

Today’s podcast features Jonas Bonér, the creator of the Akka framework.  If you’ve been listening to the podcast, especially to Episode #37 with Alex Miller on Java Concurrency, here is an alternative approach to providing scalability on the Java VM.

Akka features an implementation of Actors, Software Transactional Memory, and Transactors, a hybrid approach to working with STM inside of Actors themselves.  Jonas also provides a mechanism for writing these components inside of the Java language as well.

Actors are not a direct part of the Scala language. Rather, they are implemented as a library.  There are, in fact, at least three implementations.  Jonas Bonér’s Akka framework includes actors as well as access to Software Transactional Memory.  In this episode, my colleague Jamie Allen and I interview Jonas to try to pull apart what Actors and Software Transactional Memory are, and how they can help developers write highly scalable, concurrent applications.
