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 Bonr, Creator of AkkaAbout the Technology Mission 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 techniquesWhat 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 designsAbout the AuthorDuncan DeVore, Sean Walsh, and Brian Hanafee are seasoned architects with experience building and deploying reactive systems in production Table of ContentsPARTFUNDAMENTALS What is a reactive application Getting started with Akka Understanding Akka PARTBUILDING A REACTIVE APPLICATION Mapping from domain to toolkit Domain driven design Using remote actors Reactive streaming CQRS and Event Sourcing A reactive interfaceProduction readiness
