Understanding Akka Cluster Through Raspberry-Pi Cluster Visualization

Conference

Explaining how clustering works in general, and Akka Cluster specifically, is well worth the effort. Ask anyone who "gets it". As someone who has taught Akka Cluster courses many times over, I was always left unsatisfied after explaining the key concepts behind it in front of a white board. What I will explain and demonstrate live using a 5-node Raspberry-Pi based Akka Cluster, is how a powerful visualisation of the state of the nodes in a cluster can transform this complicated topic into one that is easy to grasp for anyone. Not only that: my personal experience has shown that it can actually transform a rather passive observer into someone who starts asking questions that demonstrate the fact that they fully grasp it. The fact that we use a physical cluster to demo and explain Akka Cluster is instrumental for this. I will conclude the talk by giving an overview how the Raspberry-Pi cluster is built along with the tooling that is used to put the demos together.
