Event-driven architectures are on the rise. They promise 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 you 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 pitfalls you should be aware of. For example, event notifications used inappropriately can lead to tighter coupling or cyclic dependencies between components. It’s 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.

Join Bernd Rücker to discover the concepts, advantages, and pitfalls of event-driven utopia through real-life stories and source code examples.

Prerequisite knowledge

  • A basic understanding of distributed systems, microservices, or events (useful but not required)

What you'll learn

  • Understand the different meanings of event-driven, the advantages of the different approaches, and the pitfalls of the approaches
  • Discover some concrete ideas on what to do and not to do in the next projects
