### 1. 可用区故切换
|
|
|
|
|
|
|
|
可用区切换的场景：
|
|
|
|
|
|
|
|
> 某个可用区内部出现系统性故障, 例如可用区VM之间网络不同； 切换方案：1）如果主可用区故障，则进行数据库切换 + 流量切换到副可用区； 2）如果副可用区故障，则流量切换到主可用区；
|
|
|
|
>
|
|
|
|
> 可用区之间的网络出现故障。例如az1 <--> az2 网络不通； 切换方案：流量切换到主可用区
|
|
|
|
|
|
|
|
|
|
|
|
#### 1.1 流量切换到主可用区（AZ1）
|
|
|
|
|
|
|
|
副可用区出现故障的场景，细分如下2个场景：
|
|
|
|
|
|
|
|
- 副可用区所在的外部负载均衡器正常: 在副可用区所在的负载均衡器上将流量切换到主可用区（AZ1）
|
|
|
|
|
|
|
|
- 副可用区所在的外部负载均衡器异常： 切换问询服务器，将APP的流量引导到主可用区
|
|
|
|
|
|
|
|
#### 1.2 数据库切换 + 流量切换到副可用区（AZ2）
|
|
|
|
|
|
|
|
|
|
|
|
需要进行切换的数据库域名：
|
|
|
|
|
|
|
|
| domain | record | az1 master | az2 slave |
