Camunda
Camunda is an open-source workflow and decision automation platform that enables developers to model, execute, and monitor business processes using BPMN (Business Process Model and Notation) and DMN (Decision Model and Notation). It provides tools for designing processes visually, deploying them as microservices, and managing them through a web-based operations interface. The platform is built on Java but supports polyglot implementations through REST APIs and client libraries.
Developers should learn Camunda when building applications that require complex workflow orchestration, such as order processing systems, loan approval workflows, or customer onboarding pipelines. It is particularly useful in microservices architectures where you need to coordinate distributed services, handle long-running transactions, and ensure compliance with business rules. Camunda's visual modeling and monitoring capabilities make it ideal for scenarios where business and IT teams collaborate on process automation.
