Summary
In this chapter, we discussed the Akka framework, which is a de-facto standard for actor-oriented programming in Scala. We have learnt how to create new actors, how to define them, and how to run an actor-based application. We saw how actors are organized into actor systems, and how they work together in hierarchies. Also, we briefly discussed the patterns that Akka provides for working with actors and futures.
In the next chapter, we will see the usage of the actors model in practice by looking at an example application implemented with this model.
