译者按：可⽤区举例：AWS可⽤区：http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions- availability-zones.html 在可⽤区之间传播Node的⼀个关键原因是：当整个区域停⽌时，⼯作负载可以转移到健康区域。因此，当⼀个区域中 的所有Node都不健康时，那么Node Controller就以正常速率 yaml⽂件上，调⽤ kubectl replace -f 也可实现相同的效果。 27-Ingress Resources 128 Failing across availability zones（跨可⽤区的故障） 不同cloud provider之间，跨故障域的流量传播技术有所不同。有关详细信息，请查看Ingress Controller相关的⽂档。 有关在federated clu
