Kubernetes is Google’s leading container orchestration engine. Its resource scheduling algorithm consists of two processes: pre-selection and optimization. The pre-selection process needs to traverse all nodes, which is time-consuming, the improved scheduling algorithm proposes to directly optimize the number of nodes that meet the conditions without having to traverse all, which is expected to improve the scheduling efficiency. For the optimization process, only the CPU and memory usage applied by the pod itself are considered, and the resource utilization of the node itself is not considered. The improved resource scheduling comprehensively considers CPU, memory, network, IO indicators. The improved algorithm is verified through experiments, which can adapt to more complex internet application environments, thereby improving the load balancing efficiency of the cluster.
