Azure刚刚发布在同一个Cloud Service下支持多个公网IP地址的功能。
这个功能主要是用于：
当相同的端口需要公用相同的LoadBalance时。
比如：
一种使用场景是多组Web服务器被一组安全设备保护，每组服务器有自己独立的IP地址，如下图：
这时需要：
-
为CloudService添加多个VIP地址：
PS C:Usershengz> Add-AzureVirtualIP -ServiceName hwmvip -VirtualIPName vip1

创建三组不同的SLB和LBS，分别用原有的VIP和新增加的VIP

可以看到我们预期的配置在两台服务器上实现了。两台服务器各属于3个不同的负载均衡组，三个负载均衡组各对应一个IP地址，对外发布的端口号都是80。
至此配置结束。
