+## Cloud provider resource quotas {#quota-issues}
 
-<!--
-Normally the number of nodes in a cluster is controlled by the value `NUM_NODES` in the platform-specific `config-default.sh` file (for example, see [GCE's `config-default.sh`](http://releases.k8s.io/{{< param "githubbranch" >}}/cluster/gce/config-default.sh)).

-中的 `NUM_NODES` 参数控制。
-
-<!--
-Simply changing that value to something very large, however, may cause the setup script to fail for many cloud providers. A GCE deployment, for example, will run in to quota issues and fail to bring the cluster up.
--->
-但是，在许多云供应商的平台上，仅将该值更改为非常大的值，可能会导致安装脚本运行失败。例如，在 GCE，由于配额问题，集群会启动失败。

-    * 路由
-    * 目标池
-* 由于某些云供应商会对虚拟机的创建进行流控，因此需要对设置脚本进行更改，使其以较小的批次启动新的节点，并且之间有等待时间。

-### Etcd storage
+<!--  
+## Control plane components
+
+For a large cluster, you need a control plane with sufficient compute and other
+resources.
+
+Typically you would run one or two control plane instances per failure zone,
+scaling those instances vertically first and then scaling horizontally after reaching
+the point of falling returns to (vertical) scale.
 -->
-### Etcd 存储
+## 控制面组件
 
-<!--
-To improve performance of large clusters, we store events in a separate dedicated etcd instance.
+对于大型集群，你需要一个具有足够计算能力和其他资源的控制平面。
+
+通常，你将在每个故障区域运行一个或两个控制平面实例，
+先垂直缩放这些实例，然后在到达下降点（垂直）后再水平缩放。
+
+<!-- 
+You should run at least one instance per failure zone to provide fault-tolerance. Kubernetes
+nodes do not automatically steer traffic towards control-plane endpoints that are in the
+same failure zone; however, your cloud provider might have its own mechanisms to do this.
+
+For example, using a managed load balancer, you configure the load balancer to send traffic
+that originates from the kubelet and Pods in failure zone _A_, and direct that traffic only
+to the control plane hosts that are also in zone _A_. If a single control-plane host or
+endpoint failure zone _A_ goes offline, that means that all the control-plane traffic for
+nodes in zone _A_ is now being sent between zones. Running multiple control plane hosts in
+each zone makes that outcome less likely.
 -->
-为了提高大规模集群的性能，我们将事件存储在专用的 etcd 实例中。
+你应该在每个故障区域至少应运行一个实例，以提供容错能力。 
+Kubernetes 节点不会自动将流量引向相同故障区域中的控制平面端点。 
+但是，你的云供应商可能有自己的机制来执行此操作。
+
+例如，使用托管的负载均衡器时，你可以配置负载均衡器发送源自故障区域 _A_ 中的 kubelet 和 Pod 的流量，
+并将该流量仅定向到也位于区域 _A_ 中的控制平面主机。 
+如果单个控制平面主机或端点故障区域 _A_ 脱机，则意味着区域 _A_ 中的节点的所有控制平面流量现在都在区域之间发送。
+在每个区域中运行多个控制平面主机能降低出现这种结果的可能性。

-To prevent memory leaks or other resource issues in [cluster addons](https://releases.k8s.io/{{< param "githubbranch" >}}/cluster/addons) from consuming all the resources available on a node, Kubernetes sets resource limits on addon containers to limit the CPU and Memory resources they can consume (See PR [#10653](http://pr.k8s.io/10653/files) and [#10778](http://pr.k8s.io/10778/files)).

The addons consume a lot more resources when running on large deployment clusters (see [#5880](http://issue.k8s.io/5880#issuecomment-113984085)). So, if a large cluster is deployed without adjusting these values, the addons may continuously get killed because they keep hitting the limits.

-除了 Heapster 之外，这些限制都是静态的，并且限制是基于 4 节点集群上运行的插件数据得出的（请参阅 [#10335](http://issue.k8s.io/10335#issuecomment-117861225)）。在大规模集群上运行时，插件会消耗大量资源（请参阅 [#5880](http://issue.k8s.io/5880#issuecomment-113984085)）。因此，如果在不调整这些值的情况下部署了大规模集群，插件容器可能会由于达到限制而不断被杀死。
