Reactive Application Development

by Duncan K. DeVore

SummaryReactive Application Development is a hands-on guide that teaches you how to build reliable enterprise applications using reactive design patterns.Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.Foreword by Jonas Bonér, Creator of Akka About the TechnologyMission-critical applications have to respond instantly to changes in load, recover gracefully from failure, and satisfy exacting requirements for performance, cost, and reliability. That's no small task! Reactive designs make it easier to meet these demands through modular, message-driven architecture, innovative tooling, and cloud-based infrastructure.About the BookReactive Application Development teaches you how to build reliable enterprise applications using reactive design patterns. This hands-on guide begins by exposing you to the reactive mental model, along with a survey of core technologies like the Akka actors framework. Then, you'll build a proof-of-concept system in Scala, and learn to use patterns like CQRS and Event Sourcing. You'll master the principles of reactive design as you implement elasticity and resilience, integrate with traditional architectures, and learn powerful testing techniques.What's InsideDesigning elastic domain modelsBuilding fault-tolerant systemsEfficiently handling large data volumesExamples can be built in Scala or JavaAbout the Reader Written for Java or Scala programmers familiar with distributed application designs.About the AuthorDuncan DeVore, Sean Walsh, and Brian Hanafee are seasoned architects with experience building and deploying reactive systems in production.

[David Stevenson · Rating 4 out of 5]

I like this book a lot but unfortunately by the time I got to read it in 2020, Akka has moved on and some of the content is getting dated.

Specifically there is a lot of use of Akka Remoting, but scant coverage of Akka Cluster. The official Akka docs and other resources nowadays discourage direct use of Akka Remoting and point towards use of higher level Akka Cluster instead.

This book will help with understanding Akka concepts, and has some fun example programs, but you’ll want to check other resources to learn how to use Akka Cluster and other updated APIs.

The final chapter has a lot of useful pointers related to making your application production ready.
