Reading:Reactive Messaging Patte

From:
Reactive Messaging Patterns With the Actor Model: Applications and Integration in Scala and Akka

Reactive applications are designed to do the following:
• React to users and other application components: Reactive applications meet or　exceed application response time to nonfunctional requirements.
• React to failure: Software is designed with the ability to recover at every component type by making resilience a central feature.
• React to load: Reactive applications tend to avoid shared resource contention by
managing discrete resources (for example, system entities) separately. This design constraint allows for system elasticity and high throughput.
• React to messages: The principle design philosophy of reactive applications is
message-driven through asynchronous messaging at its core.
