Abstract

Abstract: With the development of cloud computing and container virtualization, the microservice architecture has received more and more attention. While microservices bring many benefits, they also bring some challenges. A user's request may require multiple microservices to collaborate, and chained invocations between microservices result in higher latency than a monolithic architecture. In this paper, we propose a dynamic priority based weighted scheduling algorithm for the problem that the latency of chained-service requests is too long in the case of high concurrency. Experiments show that the algorithm can reduce the latency of chained-service requests effectively in the case of little impact on the latency of leaf-service requests.
