Abstract:  As the core of large-scale complex equipment manufacturing， industrial software plays an important role in realizing Industry 4.0， but China’s industrial software faces the problem of stuck neck. This paper analyzes the development situation and future strategic needs of civil aircraft industrial software， introduces the Internet micro-services architecture technology， designs the civil aircraft industrial software architecture for the entire civil aircraft industry chain， and applies it to a civil aircraft manufacturing enterprise. The enterprise innovates the concept of “business + technology”， realizes business process-oriented micro-services and technology mid-stage micro-services， and adopts the lean management model to finely manage huge and complex business modules and public technology modules. The system has been in trial operation for half a year， and the success rate of continuous release and delivery version has reached 98%， and the quality factor of development is getting higher and higher. Although affected by the epidemic， the success rate of a release that passes software testing is still significantly increased by 75%.
