Bernd Rücker - Co-founder and Chief Technologist of Camunda and co-author of “Real-Life BPMN"

These days, many teams favor loose coupling, isolation and autonomy of services and therefore typically opt for event-driven and reactive architectures, using a communication pattern known as choreography.​
Bernd Rücker believes that choreography is beneficial in some situations, but that it is far from the holy grail of integration.​
In some scenarios, it increases coupling, often accidentally and to a dangerous degree. Orchestration is a better choice for some situations but is often bashed for introducing tight coupling. Bernd will debunk some of these myths and show how orchestration can even reduce coupling in some situations and work in an asynchronous, message-driven fashion [...]
