<!--
The main implementation of a Kubernetes API server is [kube-apiserver](/docs/reference/generated/kube-apiserver/).
kube-apiserver is designed to scale horizontally&mdash;that is, it scales by deploying more instances.
You can run several instances of kube-apiserver and balance traffic between those instances.

Kubernetes API 服务器的主要实现是 [kube-apiserver](/zh-cn/docs/reference/command-line-tools-reference/kube-apiserver/)。
`kube-apiserver` 设计上考虑了水平扩缩,也就是说,它可通过部署多个实例来进行扩缩。
你可以运行 `kube-apiserver` 的多个实例,并在这些实例之间平衡流量。
