What is Akka? — An open source project that provides a simpler, single programming model - one way of coding for concurrent and distributed applications - the actor programming model. Akka’s primary goal is to make it simpler to build applications that are deployed in the cloud or run on devices with many cores and that efficiently leverage the full capacity of the computing power available. It’s a toolkit that provides an actor model, runtime, and required supporting tools for building scalable applications.
