The latest episode of the Camunda Nation podcast is live, and it features an interview with Mackenzie Clark, the maintainer of the open source Rust client library for Zeebe – Zeebest.
Extract from 00:17:18:
Mackenzie: Another reason I liked Zeebe a lot is they were using BPMN – which was (an) ISO standard format – for describing workflows, and I think Conductor was not using BPMN – or they had to have some kind of adapter. And so that was another bonus, is it had that legitimacy of ISO.
Josh: Yeah, I think Conductor uses its own YAML format, and then from the YAML it generates a diagram, whereas with Zeebe you can go GUI-first and it generates XML in the background.
Mackenzie: Yeah. That XML, the “living document” strategy for describing things – the flow of things at a higher level – is just so incredibly valuable. One of the things I’ve seen a lot happen in orgs that adopt a kind of microservice strategy is that you get these little teams that go off and build microservices, and we just kind of throw them out there – we throw them on Kub(ernetes) or on VMs or something, and then: how do you debug this giant distributed thing?
You end up kind of building those abstractly – not with any kind of formal, codified way; but you start building those high-level workflow abstractions between these microservices.
And with Zeebe and BPMN, you’re very straight-forward about “what are we actually doing?” There’s no confusion about what you’re making: it is a workflow that is a business process. And those little boxes in your workflow, those little processes correspond to a microservice. Not everybody has to use the same language, and not everybody has to use the same paradigms, but they all feed up to that high-level business process.
And that was where it really clicked for me. I feel like when orgs are adopting microservices, they kind of miss that.
