Linux distributions • Cons • O(N^2) in control plane / O(N) in data plane • Poor in scheduling algorithm • Iptables rules are difficult to debug IPVS mode • Services are organized in hash table • IPVS time complexity in control/data plane • Stably runs for two decades • Support rich scheduling algorithm • Cons • Performance cost caused by conntrack • Some bugs How to optimize • Guidelines •

encryption: best practices Managing DEKs: ● Generate DEKs locally ● Use a strong cryptographic algorithm ● For easy access, store the DEK near the data that it encrypts ● Ensure DEKs are encrypted at

请注意，如果某些pod的容器未设置相应的资源请求，则不会定义pod的CPU利⽤率，并且autoscaler不会对该指标 采取任何操作。有关⾃动伸缩算法如何⼯作的更多信息，阅读 autoscaling algorithm design document 。 对于per-pod的⾃定义指标，Controller的功能类似于per-pod的资源指标，除了它适⽤于原始值⽽⾮利⽤率值。 对于对象的指标，获取单个指
