Abstract The system based on microservice architecture is a trend of software system development in the future. As there are many independent micro services in the system based on micro services, the reliability evaluation of these micro services and the impact of their reliability on the system reliability have become a problem worth studying. Based on the reliability evaluation of the system based on the service dependency graph and the fault tree, this paper proposes a scheme of automatically generating the service dependency graph with the help of the service registry, and improving the reliability model of service fault tree. When establishing the fault tree, the influence of the system’s fault-tolerant mechanism and different probability of execution path on the system reliability is taken into account, thus improving the accuracy of the model analysis system fault rate.
