Viktor Klang, tech lead of Akka at Typesafe, discusses scaling software with actors at the 2012 Northeast Scala Symposium. Traditional approaches to concurrency and distribution force the issue of choosing between productivity and scalability. The cause of that has been the wrong tools and the wrong layer of abstraction and Akka is here to change that.
Akka is a unified runtime and programming model for scaling both UP (utilizing multi-core processors) and OUT (utilizing the grid/cloud). With Akka 2.0 this will be taken to a whole new level, "Distributed by Design".
The Northeast Scala Symposium is a yearly gathering of the Scala community, made possible by efforts of Boston, Philadelphia, and New York Scala Enthusiasts.
