Transactional Email Microservice with Zeebe and NestJS

NestJS is a JavaScript Microservices framework for Node.js inspired by Angular. For some time now, front-end developers have been able to get the benefits of configuration by convention, dependency injection, and composition using decorators to build code bases whose structure can scale. Now it’s time for backend developers to get the same benefits. NestJS is a framework that clearly meets a need felt in the community – it was the fastest growing Node.js framework in 2018 (measured by GitHub stars). NestJS leverages TypeScript, decorators, and the MVC architecture to enable developers to build applications that communicate over REST, WebSockets, gRPC, and GraphQL. With a new library from Dan Shapir – nestjs-zeebe – you can now integrate Zeebe into a NestJS…

Zeebe and IoT: Node-RED

Patrick (Paddy) Dehn and Cornelius Suermann join me on the Camunda Nation podcast this week to talk about Zeebe, IoT, and workflow automation. Paddy is a developer working on Operate, the web-based UI for Zeebe workflow inspection and management, and Cornelius is the engineering director for Camunda Cloud. They are also both massive IoT nerds. Paddy is the author of the open-source Zeebe nodes for Node-RED. We talk about their personal home automation projects, the Zeebe nodes for Node-RED, and some of the possibilities for massively scaled workflow automation in the cloud with Camunda Cloud, Zeebe, and IoT. Check them out on GitHub: Cornelius on GitHub Paddy on GitHub

Zeebe and Kubernetes: Introducing Mauricio Salatino

Mauricio Salatino has joined the Zeebe team as a Developer Advocate. He was previously a developer at Red Hat on jBPM, and then at Alfresco on Activiti. He’s also written courses on using Kubernetes. He’s based in London, and is happy to meet people from the Zeebe community at meetups and for coffee. In September, Mauricio sat down to talk with the Camunda Nation Podcast about Zeebe and Kubernetes. You can reach Mauricio in the Zeebe Slack and the Forum, follow him on Twitter @salaboy, and check him out on GitHub. You can subscribe to the Zeebe Nation podcast on iTunes, Spotify, Google Podcasts, Stitcher, or old-school RSS.

Announcing Camunda Cloud

Today at CamundaCon, our CTO Daniel Meyer (who also happens to have written more than 100,000 lines of Zeebe code) unveiled Camunda Cloud. This is a big step for Camunda. It’s the first time in the company’s history that we’re offering a workflow service in the cloud, and we’re super excited to be starting down this path. And we’re sharing the news here on the Zeebe blog because Zeebe is the workflow engine that sits at the heart of Camunda Cloud.

Zeebe on Camunda Cloud: Getting Started

Zeebe is now available as a managed service in the Camunda Cloud. This means that you can experiment with Zeebe without having to set up and manage the broker. Currently it is in beta, and you can apply here to get an account. You will be able do both development and go to production without having to concern yourself with deploying and managing the Zeebe broker on Kubernetes – you can leverage the expertise of the Camunda Cloud Engineering team, who do that full-time. You can still run Zeebe locally or deploy it to the cloud yourself, so this is an additional option rather than a change to anything. This post is a guide to getting started with the Zeebe…

Using the Zeebe Kafka Connector to Orchestrate, Integrate, and More

The Zeebe team just implemented a Kafka Connect Zeebe connector. This is a feature users have been asking for since the start of the project, so let’s give it a closer look. What is Kafka Connect? Kafka Connect is the ecosystem of connectors into or out of Kafka. There are lots of existing connectors, e.g. for databases, key-value stores or file systems. So for example you can read data from a RDMS and push it to Elasticsearch or flat files.

Coming in Zeebe 0.21: Long-polling workers

The upcoming 0.21 release of Zeebe includes a feature many users have been asking for: long-polling for workers. And make sure you stay tuned to the end to find out what a massive deal it is. Zeebe is a radical re-imagining of the workflow engine for the modern world: it uses event sourcing to interpret workflows over immutable streams. In the Zeebe model, workers are de-coupled from the broker. Conceptually, workers “subscribe” to task types on the broker to service. In terms of actual implementation, workers poll the broker for the task type they service. This allows the broker to have no stateful knowledge about workers. The Problem With Polling Every request to the broker for work from a worker…

Scaling Zeebe Horizontally: A Simple Benchmark

Note: The specific performance metrics in this blog post are from an earlier release of Zeebe. Since this post was published, work has been done to stabilise Zeebe clusters, and this has changed the performance envelope. You can follow the steps in this blog post to test the current release of Zeebe yourself, and derive the current performance envelope. Zeebe advertises itself as being a “horizontally-scalable workflow engine”. In this post, we cover what that means and how to measure it.
