Introduction to reactive programming: Hands-on with Akka, Java, and Scala

Duncan DeVore (Lightbend), Henrik Engstrom (Lightbend)
9:00am–5:00pm Monday, 07/20/2015
Training D134

This training continues on to Tuesday.

Prerequisites

Code examples and exercises will be written primarily in Java with some Scala, so a basic knowledge of the Java language is required.

Computer Requirements

In addition, attendees should bring their own laptop with admin rights, have access to the internet, and Java 8 installed. Both Windows and OSX environments are supported.

Overview

Are you building distributed apps? If so, you need those apps to be responsive, resilient, and elastic in the face of both failure and extreme load. Reactive programming is a practical way to make sure you are meeting the needs of your customers and ensuring that you are not losing out on revenue.

This two-day training course will explore the tenets of reactive programming through first establishing the reasons why from both a technical and business perspective. Then we will dive in with hands-on exercises that lead to a fully functional reactive application, that is message-driven, elastic and resilient by the conclusion of the course.

Topics

  • Overview
  • Why reactive?
  • Establishing our analogy
  • Handling the basics of a reactive application
  • Introducing and understanding bottlenecks
  • Resolving bottlenecks through elasticity
  • Introducing and understanding failure
  • Resolving failure through self-healing

Audience

Architects, developers, technical leaders, and anyone who is interested in learning about the basics of reactive programming and distributed computing with Akka, Java, and Scala.
