Abstract： In the face of diversified security threats, a resilience-driven microservices orchestration framework(RMOF) is proposed for the scheduling problem under the microservices architecture. RMOF framework takes many aspects into account, including system′s resilience objectives, risks, security techniques, and the cost of implementation. Under the constraints of resilience objectives, RMOF establishes the microservice orchestration model. On these basis designs, an algorithm named GA-PP(Partially Preserve Genetic Algorithm) is implemented to solve the orchestration model. Finally, through model calculations, a microservice chain, which meets the constraints of resilience, can be formed. The experimental results show that RMOF can effectively establish the orchestration model, which is used to generate microservice chain, under the constraint of resilience, and ultimately improve the resilience of the system.
