In order to give full play to the advantages of collaborative cloud-edge computing system and reduce the delay of supervisory control and data acquisition (SCADA) service, this paper proposes a microservice placement method of SCADA service in collaborative cloud-edge computing system. Firstly, the SCADA application is partitioned into multiple microservices and a sequential logic model of microservices is formulated. Then, an optimization model of microservice placement in the collaborative cloud-edge computing system is proposed and the placement results with minimum service delay are solved using an improved differential evolution algorithm. Finally, the comparison of different placement strategies and the influence of computation and communication resources on the placement results are investigated in simulation. Simulation results verify the effectiveness of the proposed method.
