Akka: Simpler Scalability, Fault-Tolerance, Concurrency & Remoting through Actors
Jonas Bonér

We believe that writing correct concurrent, fault-tolerant and scalable applications is too hard. Most of the time it's because we are using the wrong tools and the wrong level of abstraction. The Akka framework is here to change that. Akka is leveraging Scala, and using the Actor Model (its own Actors impl) together with STM it raises the abstraction level and provides a better platform to build correct concurrent and scalable applications. For fault-tolerance it adopts the "Let it crash" model which have been used with great success in the Telecom industry to build applications that self-heals, systems that never stop. Akka's Remote Actors (backed by a scalable non-blocking IO impl), provides the abstraction for transparent distribution and the basis for truly scalable and fault-tolerant applications. In this talk we discuss what Akka is, how it can be used to solve hard problems and the ideas behind its design and implementation.
