The fundamentals of using REST have helped create the distributed systems we know today. But as architectures have changed and systems over network have become more complex it's limitations have caused problem. In an interesting turn of events one of the ways these limitations can be overcome is by adding a workflow engine to your architecture. In the talk, I'll demonstrate live how to integrate Camunda into a running microservice architecture and demonstrate the problems that solves.

This talk will reflect on the role of BPMN from a software engineering perspective. It will then take a reverse tour through the BP-M-N acronym: N-What does the notation of BPMN tell us, and how can it be optimized via eye-tracking experiments? M-The model aspect will be discussed with respect to model theory and the question what is considered relevant in BPMN - and what not. BP-This final issue leads to a proposal for covering more human-oriented aspects by complementing BPMN with vision videos, a concept that was developed at Leibniz Universität Hannover.
