Course Description

The full capabilities of Akka come from the ability to scale using clustering and networking. In this course, you will learn how to build, manage, and configure a cluster, manage network communication within an application, and use advanced utilities.

Learning Objectives


  • start the course
  • describe the advantages of clusters and how they work
  • create a cluster and actors that can join its nodes
  • manage and remove cluster members
  • subscribe actors to cluster events

Advanced Clustering

  • distribute actors across nodes using cluster sharding
  • publish and send messages to members
  • communicate with cluster members from outside the cluster using cluster client
  • create routers that monitor or deploy routes on cluster nodes
  • use Cluster Metrics Extension to monitor cluster health and perform load balancing
  • manage clusters using a JMX console or command lines

Other Network Features

  • monitor and manage actors remotely and enhance remote security
  • use serialization to convert objects to and retrieve objects from simple byte data
  • describe the Akka I/O implementation
  • create and manage connections using TCP
  • use the Akka-Camel module to send and receive messages

Akka Utilities

  • use the event stream to publish events
  • set up logging within an Akka application
  • use the scheduler to create future events
  • use circuit breakers to avoid "hanging" applications caused by nonresponsive services
  • create extensions to add your own features to Akka
  • use Akka along with Sprint or any other JEE application
  • use Akka along with Play framework as a service backend
  • separate Akka message into its own module, group actors into modules, and deploy those modules independently
  • implement continuous integration and deploy large-scale Akka-based applications

Practice: Akka Clusters

  • create a clustered Akka application including logging and event subscription
