Below is a comparison list from the perspective of node count and node configuration. Below is a comparison of choosing a few large clusters versus many small clusters: Feature A few large clusters Many small clusters Resource utilization High Low Node management overhead Low High Resource scaling range Large Small Resource scheduling range Large Small Efficiency of inter-application communication High Low Cluster operations difficulty High Low Cluster version diversity Low High Blast radius Large Small Below is a comparison of choosing a few high-spec nodes versus many low-spec nodes:WeChat Official AccountKubernetesClusterPlanningOperationsNodehttps://www.chenshaowen.com/en/blog/how-to-change-kubelet-config.htmlWed, 23 Jun 2021 00:00:00 +0000Wed, 23 Jun 2021 00:00:00 +0000https://www.chenshaowen.com/en/blog/how-to-change-kubelet-config.html1.
