Reactive Design Patterns is a clearly written guide for building message-driven distributed systems that are resilient, responsive, and elastic. In this book you'll find patterns for messaging, flow control, resource management, and concurrency, along with practical issues like test-friendly designs. All patterns include concrete examples using Scala and Akka.
Inside:Most examples use Scala, Java, and Akka. Readers should be familiar with distributed systems.
Dr. Roland Kuhn led the Akka team at Lightbend and coauthored the Reactive Manifesto. Brian Hanafee and Jamie Allen are experienced distributed systems architects.
If the ‘Reactive Manifesto’ gave us a battle cry, this work gives us the strategic handbook for battle.

An engaging tour of distributed computing and the building blocks of responsive, resilient software.

This book is so reactive, it belongs on the left-hand side of the periodic table!
