On the other site of the spectrum we have Service Orchestration. This is basically connecting (micro) services by means of BPMN models. You would see these types of processes in enterprise environments, focussing on eliminating manual work. Typically very high volume. Think of Amazon (the webshop): processing your order is fully automated, unless something goes wrong. We'd advice to use bare Camunda for these projects, combined with an experienced Java development team.
