Content
Akka is the implementation of the Aktor model on the JVM. Akka allows the development of real cloud-native applications according to the reactive principles (The Reactive Manifesto). Akka enables clean competitive programming and correct design of distributed systems. Akka systems are resilient, powerful, elastic and decentralized.
Together we will incrementally build a sample application that illustrates the following topics:
- Akka overview
- actors
- messaging
- location
- cluster
- sharding
- singleton
- deployment on Kubernetes
- event-sourcing
- streaming
- persistence
- split-brain
- etc. We focus on a specific selection of topics to look at and understand in detail.
The actual course content may differ from the above depending on the trainer, delivery, duration and the composition of participants.

More about Akka
Akka is an open-source toolkit for building concurrent, distributed, and fault-tolerant applications on the JVM. It implements the Actor Model, originally conceived by Carl Hewitt in the 1970s, providing an elegant abstraction for managing state and behavior in distributed systems. Akka is maintained by Lightbend and serves as the foundation of many high-scale production systems worldwide.Further resources:
History
The Actor Model was first described by Carl Hewitt in 1973 and forms the theoretical foundation of Akka. Jonas Bonér founded the Akka project in 2009 and released it as open-source software. Since then, Akka has gained widespread adoption and has become the preferred solution for reactive, distributed systems on the JVM.
With the introduction of the Typed Actors API, Akka significantly improved its safety and expressiveness. The framework today underpins well-known projects such as Apache Spark and Lagom, and is used at scale by companies like LinkedIn, Twitter, and PayPal.
