Interactive Demo:
Visualizing Akka Cluster Node Lifecycles

Hugh McKee, Developer Advocate at Lightbend, Inc.

About the webinar

Akka Cluster and related Akka toolkit modules provide a powerful way to scale high performance microservices and preserve data consistency in Reactive, cloud native applications. Yet until now, much of that power is expressed behind the scenes.

In this hands-on session with Hugh McKee, O’Reilly author and Developer Advocate at Lightbend, you’ll be able to install a very simple dashboard to visualize, deploy, and interact with Akka Cluster nodes and their lifecycles. Here are the details:

  • Intro and set up (10 min) -Walking through the what and how of Akka Cluster and the browser dashboard. For those who want a head start, you can install the project directly in order to interact with the dashboard during the live session. The only prerequisites are Git, Maven, and Java 8+.
  • Cluster Dashboard (10-15 min) - we explore the sample application structure, useful CLI commands, dashboard layout, and the different states of Akka Cluster nodes.
  • Node Lifecycle Interaction (15-20min) - in this more interactive part, we’ll fully review the lifecycle of Akka Cluster nodes, how they form clusters using gossip protocols, and what happens as nodes leave, join, or are forcibly removed from the cluster or become unreachable.
  • Q/A (5-10min) - Ask your burning questions about Akka Cluster to Hugh via the GoToWebinar Questions tab.
