Understanding how to use Akka clusters effectively is well worth the effort. Ask anyone that “gets it.” In this discussion, we review a simple yet powerful visualization of a 5-node, RaspberryPi-based cluster to reveal the inner workings of Akka Cluster. In a matter of minutes, you will gain valuable insights into Akka clustering.

Required Knowledge

• No prior knowledge of Akka is required, just an open mind and curiosity about learning Akka

Learning Objectives
