Thanks for your comment! That is true, Akka is much more than just actors — which I tried to communicate throughout the three parts. I also tried to (hopefuly) consistently use the term akka-actors or akka-typed-actors, to underline the fact that we are dealing only with the actor module.
While Akka does offer a lot more, e.g. for clustering, I think it’s very often use in single-node, local setups. This might not be often the best option, and showcasing that might be an additional side-goal of this series.
Finally, akka-cluster is in many parts independent of the actors part, and it should be quite easy to use clustering with Monix or ZIO.
