A Glance of BPMN 2.0 and Alfresco BPM Engine Activiti

Alfresco Activiti is a well-known open source BPM (Business Process Management) engine which may execute business processes depicted in BPMN 2.0. The authors of Alfresco Activiti developed jBPM for Red Hat previously, and after they left Alfresco in 2016, they forked Activiti code and created another open source workflow engine called Flowable. Later, Alfresco Activiti was re-branded as Alfresco Process Services (APS).

Before Activiti, the market of BPMN engines is already very crowded, Oracle, SAP, IBM and many others offer solutions. There are even more BPMN diagram tools, such as MS Visio,  LucidChart, MagicDraw, yEd and Sparx EA, etc. Among all of these solutions, Alfresco Activiti has its unique advantages, it’s an open source, Java-based, programmable, mature and well-rounded solution.
