A Node-Level Model for Service Grid

Abstract

This papers studies a high-performance node-level service grid model, which aims to solve the problem that the current pod-level service grid model affects the service operation and consumes many computing resources. The main method of the node-level service grid model is to improve pod-accompanied service grid sidecar with the node-accompanied service grid sidecar sharing of multiple pods, combined with the cut-through of user mode protocol stack and scaling of node-level service grid sidecar. By the performance comparison of pod-level service grid model and node-level service grid, we can conclude that node-level service grid model can isolate pod services without affecting service operation, significantly reduce memory consumption without multiplying with the number of pods, and largely reduce end-to-end network delay about 30% but the overall CPU consumption as the same as that of the pod service grid model. It indicates that the node service grid model can obtain better business benefits than the pod service grid model in container cloud, cloud service providers can provide grid services for more tenants with less memory resources and network latency, and adding grid services has no impact on the operation of user applications.
