Abstract

Event-driven architectures are on the rise. They promise both better decoupling of components by using an event bus and improved scalability in terms of throughput. Decoupled modules help to scale your software development efforts itself. Event streaming promises to handle ever-growing amounts of "data in motion" in real-time, event sourcing allows us to time travel, and domain events have turned out to be powerful building blocks that lead to a better understanding of underlying business requirements.  

But there are also pitfalls that you’d better be aware of. For example event-notifications used inappropriately can lead to tighter coupling or cyclic dependencies between components. It is also easy to lose sight of flows across service boundaries, making it hard to understand how core business logic is actually implemented. This can get even worse if you lack tooling to get insights into your event flows. Last but not least, the event-driven approach is not well-understood by most developers or business analysts, making it hard for companies to adopt. In this talk, I will quickly go over the concepts, the advantages, and the pitfalls of event-driven utopia. Whenever possible, I will share real-life stories or point to source code examples.

Speaker: Bernd Rücker

Co-Founder and Chief Technologist @Camunda

Throughout my 15+ years in software development, I have helped automating highly scalable core workflows at global companies including T-Mobile, Lufthansa and Zalando. I have contributed to various open source workflow engines. I am co-founder and chief technologist of Camunda, an open source software company reinventing workflow automation. I co-authored "Real-Life BPMN," a popular book about workflow modeling and automation. I regularly speak at conferences and write for various magazines. I am currently focused on new workflow automation paradigms that fit into modern architectures around distributed systems, microservices, domain-driven design, event-driven architecture and reactive systems.
