<DIV><p>Akka is a Scala-based toolkit that simplifies developing concurrent distributed applications. Perfect for high-volume applications that need to scale rapidly, Akka is an efficient foundation for event-driven systems that want to scale elastically up and out on demand, both on multi-core processors and across server nodes.</p><p><i>Akka in Action</i> is a comprehensive tutorial on building message-oriented systems using Akka. The book takes a hands-on approach, where each new concept is followed by an example that shows how it works, how to implement the code, and how to test it. Readers will explore a message-oriented event-driven application in Akka and also tackle key issues like how to model immutable messages and domain models, and apply patterns like Event Sourcing, and CQRS. The book concludes with practical advice on how to tune and customize a system built with Akka.</p><p>Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.</p></div>
