Retaining Community Knowledge on the Slack Free Tier with a Slack bot

by Josh Wulf on Dec 17 2020 in Community .

“There is a lot of valuable information in this Slack, but whenever I come back to find it, it’s gone because of the 10,000 message limit. Can we move this community to Discord, which has persistent message history?“ That message, from a community member in the Zeebe Slack, triggered a DevRel project that resulted in the Slack Archivist - a Slack bot that allows valuable conversations to be archived from the community Slack to a dedicated searchable topic in our Discourse-powered Forum.

Refactoring an Actor Model System from Nact.io to Camunda Cloud

by Josh Wulf on Dec 14 2020 in Tutorials Use cases .

This month marks the 20th anniversary of the Open Source Erlang language and the Erlang virtual machine. Renowned for its reliability, the ability to hot-patch running code, and the Actor model, Erlang has been incredibly influential in software development, particularly in scalable distributed systems. If you look through the Zeebe source code, you’ll see Actor components sprinkled throughout. Zeebe core engineer Deepthi Akkoorath did her PhD thesis in Scalable Consistency in the Multi-core Era and is a huge fan of Erlang. Read more…

Virtual Conference Swag

by Josh Wulf on Nov 26 2020 in Community .

I loved that as a developer - in fact, I first met (now, fellow-) Camunda Developer Advocate Niall Deehan at the Camunda booth when speaking at NDC Oslo, in 2017. A essential part of the conference experience is getting some cool swag. My wardrobe is literally 70% conference and swag t-shirts. Read more…

Orchestrating Microservices with Zeebe

by Salaboy on Oct 28 2020 in Kubernetes Zeebe Orchestration Spring Cloud .

Last Tuesday, I gave a presentation about “Orchestrating Microservices with Zeebe” for a London Meetup. In this blog post you can find the slides and video for the presentation - but first, a few words about the content of the presentation. I’ve focused more on the orchestration side of the example that you can find here: http://github.com/salaboy/from-monolith-to-k8s. Instead of spending time discussing the frameworks used for the example, I’ve highlighted the importance of exposing the business logic and flow of our applications to other relevant stakeholders.

You can find the Demo application, installation instructions, and some videos of the application and the tools in action on GitHub. Read more…
