Are MicroServices the Death of BPM and Case Management? By Jan Kettenis

 

When reading about MicroServices you could get the impression that orchestrated business processes or even case management applications will soon become legacy. I seriously doubt that, considering the challenges you will face with creating a landscape of MicroServices that will be able to support some of the characteristics that gave birth to BPM and Case Management in the first place. Also, Martin Fowler’s primary guideline concerning MicroServices is "don’t even consider MicroServices unless you have a system that’s too complex to manage as a monolith". In the following I discuss the issues you might face with Business Process and Case Management in a pure MicroServices architecture. My conclusion being that MicroServices will not be the death of BPMN or Case Management. On the contrary, it probably is going to help delivering on some of their promises we so far seem not always be able to deliver upon.

MicroServices are supposed to be stateless, and its business capability should not depend on others to complete its work, which makes it like the opposite. In BPMN the order in which activities are executed is prescribed or ‘orchestrated’ as we say, by ‘flows’ that go from one point to another. Read the complete article here.
