Secondary topics:  Best Practice

Who is this presentation for?

  • Enterprise architects and developers

Prerequisite knowledge

  • Basic knowledge of distributed systems and messaging

What you'll learn

  • Understand why commands are one important ingredient to reduce coupling


With the rise of microservices and serverless clouds, the world is moving toward event-driven architectures composed of diverse, distributed systems and services. In this world, we have to manage business transactions and end-to-end processes that cross the boundary of individual services. Although event-driven choreography is fundamental to achieving nicely decoupled systems, complex event chains can cause headaches.

Bernd Rücker explains why transforming certain events into commands is beneficial and how to avoid losing sight of larger-scale flows. Bernd also demonstrates how to leverage existing technology to handle complex flows that require state handling, proper reactions on errors, timeouts, and compensating actions.

Bernd Rücker is a technology evangelist and cofounder at Camunda. Bernd started developing Java more than 15 years ago, when the world was still three-tiered and using ACID transactions. Previously, he was a consultant, coaching clients on their software projects and helping them implement business logic centered around long running flows. Bernd is excited about how flows will be implemented in next-generation architectures.
