The traditional workflow framework enhances the design orchestration and manageability of process tasks, but there are problems such as the lack of runtime expansion of the process engine, insufficient flexibility of task participants, and large change costs of complex process forms. This paper presents a containerized flexible microservices process development framework, combining domain-driven design, container-based microservices, dynamic organization key points and other technical mechanisms to improve workflow implementation efficiency, reduce development costs, and better solve the above problems. After the experimental analysis, the flexibility is enhanced and the cost is smaller, and the effectiveness of the framework and method is verified in practical projects.
