Lightbend Akka Cluster - Fundamentals

This course will peel back the curtain and show you what happens inside of an Akka Cluster.

About This Course

Akka Cluster is a powerful set of tools used to build modern distributed and reactive systems. With it, you can build systems that can scale in ways that weren't possible using traditional architectures.

Using Akka Cluster properly can be challenging. An improperly configured cluster can create more problems than it solves. This course will attempt to de-mystify some aspects of Akka Cluster. We will peel back the curtain and take a look at how the cluster works behind the scenes.

By developing a deeper knowledge of Akka Cluster we will put ourselves in a better position to create a stable, and efficient cluster.
