Lightbend Akka for Java - Professional
Overview
This three-day course introduces experienced application developers to the Akka toolkit and runtime
Students will also learn about the Reactive Manifesto and the Actor Model
These tools enable the creation of real-world, actor-based systems in Java
This course has extensive hands-on work
Each exercise builds upon prior lessons learned to produce a fully functional application
The goal is to produce a system that is both event-driven and resilient by the end of the course
Objectives
After having participated in this course you should:
know how to design scalable and fault-tolerant applications using Akka's actors
know how to configure, test, and tune Akka applications
know best practices for designing asynchronous, event-driven systems using Akka
be confident to start using Akka in production systems
