In this chapter, we will discuss how to develop Reactive Applications using the Akka Toolkit. Unlike the Shared-State Concurrency model, which does not support true Parallelism, Akka's Actor-based Concurrency model supports true Parallelism. Akka is an open source library available on Apache License Version 2.0.
We can develop applications using Akka to utilize today's multicore CPUs efficiently to improve application performance. In the old versions, Scala had the Actors library; Lightbend has removed it from Scala and moved it to the Akka Toolkit. Now the scala.actors library is no longer useful, and it is deprecated.
Akka is an Event-Driven middleware framework for building high-performance, highly Scalable, highly available, and Reliable distributed applications in Java and Scala.
In this book, we will use the latest version...
