Learn how we successfully reduced Zeebe's process execution latency with batch processing during a recent hackday.

Learn how we test and identify hard-to-find critical bugs in Zeebe, the workflow engine powering Camunda Platform 8, using property-based testing.

Monitoring is an essential facet of running applications in a production system. Through this process, organizations collect and analyze data, and determine if a program is performing as expected within set boundaries. When combined with alerting, monitoring allows for detecting unexpected system behavior to mitigate exceptional situations as fast as possible. Furthermore, tracking the performance of a system enables organizations to improve those aspects that have the biggest impact with higher priority. One essential aspect of monitoring is the list of key metrics you want to observe. There are different categories of statistics that can be of interest here. To observe the defined metrics, there are plenty of application monitoring tools on the market today. They differ in many aspects...

Directory services are an effective way to manage an organization’s users, groups, printers, devices, and more. Most organizations accomplish this using Active Directory, Apache Directory, Oracle Internet Directory, or other similar tools. Recently I worked with a customer who wanted to see how he could secure the Camunda 8 Platform and process applications with such a directory. Their requirements consisted of: Allowing Directory users to access Camunda applications (Tasklist, Operate, Optimize) Accessing secured Tasklist & Operate APIs from our custom project Securing the custom project In this article, I’ll briefly explain the 3 easy steps taken to fulfill their requirements which include: Federate users from the Directory service into Keycloak Declare an application in Identity to access Camunda APIs Configure...

Eliminate islands of automation by orchestrating processes from end to end.

During Summer Hackdays 2022, I worked on a project called “Zeebe chaos” (zbchaos), a fault injection command-line interface (CLI) tool. This allows us engineers to more easily run chaos experiments against Zeebe, build up confidence in the system’s capabilities, and discover potential weaknesses. Requirements To understand this blog post, it is useful to have a certain understanding of Kubernetes and Zeebe itself. Summer Hackdays: Hackdays are a regular event at Camunda, where people from different departments (engineering, consulting, DevRel, etc.) work together on new ideas, pet projects, and more. Check out previous Summer Hackdays here: Summer Hackdays 2020 Summer Hackdays 2019 Zeebe chaos CLI Working on the Zeebe project is not only about engineering a distributed system or a process...

Deleting process definitions in Camunda Platform 8 requires complex behavior across multiple components in the system.

At Camunda Community Summit 2022, Fidelity Investments Director of Architecture Harish Malavade shared a behind-the-scenes look at Fidelity’s digital automation platform that uses Camunda as its core workflow engine. Here are the technical details.
