Abstract
Microservice is increasingly seen as a rapidly developing architectural style that uses containerization technology to deploy, update, and scale independently and quickly. A complex microservice flow that is composed of a set of microservices can be characterized by a complex request execution path spanning multiple microservices. It is essential to aggregate quality of service (QoS) of individual microservice to provide overall QoS metrics for a complex microservice flow. Besides, leveraging the cost and performance of a complex microservice flow to find an optimal end-to-end container allocation solution with QoS guarantee is also a challenge. In this paper, we define an end-to-end QoS aggregation model for the complex microservice flow, and formulate the end-to-end container allocation problem of microservice flow as a nonlinear optimization problem, and propose an ONSGA2-DE algorithm to solve this problem. We comprehensively evaluate our modeling method and optimization algorithms on the open-source microservice benchmark Sock Shop. The results of experiments show that our method can effectively assist in the QoS management and container allocation of complex microservice flow.
