Modern applications present incredible design challenges: we expect near-realtime performance while managing petabyte-scale data and distribution across environments ranging from traditional servers to cloud systems to mobile devices. The Reactive Application model addresses these demands through new patterns designed to "react" effectively to user and system events, changes in load, competition for shared system resources, and unanticipated failures. Although reactive design patterns can be implemented using standard enterprise development tools, you best realize the benefits when you pair them with a functional programming language like Scala and an Actor-based concurrency system like Akka.
