Reactive architecture patterns allow you to build self-monitoring, self-scaling, self-growing, and self-healing systems that can react to both internal and external conditions without human intervention. These kind of systems are known as autonomic systems (our human body is one example). In this session I will show you some of the most common and most powerful reactive patterns you can use to automatically scale systems, grow systems, and self-repair systems, all using the basic language API and simple messaging. Through code samples in Java and actual run-time demonstrations, I'll show you how the patterns work and also show you sample implementations. Get ready for the future of software architecture - that you can start implementing on Monday.


  • introduction to reactive architecture
  • supervisor consumer pattern (automated microservices scalability)
  • workflow event pattern (automated asynchronous error handling)
  • producer control flow pattern (automated repairing of downstream systems)
