Lightning Talk: Dissecting Service Mesh Overheads - Xiangfeng Zhu, University of Washington

Service meshes like Istio enable highly flexible microservice deployments, but this flexibility comes at the cost of higher latency and CPU usage. It is difficult to fully understand the source of such overheads, which makes it challenging for developers to optimize service mesh configurations and to predict the impact of performance optimizations. We have developed MeshInsight, a tool to analyze and predict the performance overhead of Istio. MeshInsight decomposes the overheads into independent, yet composable components, which enables it to predict performance overheads for applications and configurations. It can help application developers to pick configurations that strike the right balance between functionality and performance, and service mesh developers can estimate the impact of optimizations on application performance. This talk will describe how MeshInsight works and show results from a study that characterizes performance overheads of a range of deployment patterns.
