Aiming at the problems that the current power grid information communication operation and maintenance system has hardware platform out-of-date service and information processing tasks cannot be completed quickly, this study proposes a migration model of micro service application system based on Spring Could to the cloud. This model migrates the power grid information communication operation and maintenance system to a cloud platform. In response to the management problems that occurred after the centralized system was migrated to the cloud and transformed into a distributed system, all system services were moved into the EDAS system to achieve one-click deployment, elastic scaling, grayscale release, and fault self-healing. In addition, a data consistency sampling verification method based on Gibbs sampling is designed to solve the problem of consistency check of huge amount of data in the cloud process. This method improves the efficiency of data consistency verification and reduces the cloud workload on the system. Afterwards, this article proves the system’s successful cloud deployment and reliable operation through the actual case of the cloud of the State Grid Anhui Electric Power SG-I6000 microservice system.
