Abstract: Workflow is an important technology for enterprise and institution informatization, workflow engine is the core of the workflow management system. However, traditional workflow engine is based on macro-kernel, that is kernel to end at the same time scheduling and services, which results in the problems of the workflow engine reconstruction and maintenance. Therefore, this paper prompts microkernel-based workflow engine to reduce the workflow engine maintenance and reconstruction difficulty.

Key words: workflow, workflow engine, microkernel
