Stateful Orchestration (or, Why Your Microservices Application Needs a Brain)
When checking in for a flight online, normal people hope that everything works the way it’s supposed to. That usually means no error messages, and at the end of the process, getting a boarding pass in your selected format.
We at Camunda, however, are not “normal people”.
A problem during check-in is a bit of a thrill for us because it gives us a peek into how a company handles software failures in a high-traffic application.
We never know exactly what’s happening under the hood, of course, but we like to speculate.
Read more…BPMN and Microservices Orchestration, Part 2 of 2: Graphical Models, Simplified Sagas, and Cross-functional Collaboration
This is part 2 in a 2-part series about BPMN and how it’s being applied to new use cases. You can find part 1 here. A sincere thanks to Bernd Rücker for his feedback during the writing of both blog posts.
Welcome back to our discussion of BPMN (Business Process Model and Notation) and its role in emerging use cases such as microservices orchestration. You don’t have to read the posts in order to be able to follow along, but if you’re new to BPMN, you might find it helpful to start with part 1.
To recap, the first post covered:
- An introduction to BPMN
- Why a well-established standard that thrived in the past can thrive in the future, too
- Common orchestration patterns supported by BPMN
- The current state and future plans of BPMN in Zeebe
In this part 2, we’ll:
- Look at examples where using a graphical model instead of a code-based model simplifies workflow definition
- Dive into tooling for building graphical models in BPMN (and other ways to define workflows)
- Reassure you that BPMN’s graphical models are nothing to be afraid of–even if you’ve had a bad experience with graphical models in the past
BPMN and Microservices Orchestration, Part 1 of 2: Flow Languages, Engines, and Timeless Patterns
A sincere thanks to Bernd Rücker for his feedback during the writing of this blog post.
This is part 1 of 2 in a 2-part blog post series. Part 2 is available here.
We’re building Zeebe to be a next-generation workflow engine for emerging use cases such as microservices orchestration–use cases that may require an engine to handle hundreds of thousands (or millions) of new workflow instances per second.
And to do that, we’re using a graphical modeling standard that’s been around for almost 15 years: BPMN (Business Process Model and Notation).

Read more…We've Opened the 2018 Microservices Orchestration Survey, and We're Looking For Your Input
When we talk about Zeebe, we also talk a lot about the challenges that organizations face when managing business processes that span many independent microservices.
“Microservices orchestration” is a useful term for describing one potential solution to this problem. But every organization will take a different approach to a microservices architecture, and we want to be sure we have a clear understanding of what microservices orchestration means to the many different users who might benefit from Zeebe.

Read more…Benchmarking Zeebe: An Intro to How Zeebe Scales Horizontally and How We Measure It
In the past few weeks, we’ve mentioned Zeebe’s performance in horizontal scalability benchmarks that we run internally, but we haven’t yet explained how exactly we run these benchmarks. We decided we should take it one step further and open up the benchmark to anyone who wants to try it.
