Azure一個Cloud Service支援多個公網地址

Azure剛剛釋出在同一個Cloud Service下支援多個公網IP地址的功能。

這個功能主要是用於：

當相同的埠需要公用相同的LoadBalance時。

比如：

 

一種使用場景是多組Web伺服器被一組安全裝置保護，每組伺服器有自己獨立的IP地址，如下圖：

 

這時需要：

  1. 為CloudService新增多個VIP地址：

    PS C:\Users\hengz> Add-AzureVirtualIP -ServiceName hwmvip -VirtualIPName vip1

    OperationDescription OperationId OperationStatus
    -------------------- ----------- ---------------
    Add-AzureVirtualIP 14a912b8-5f03-4ecd-aecb-f97e679553e1 Succeeded

    PS C:\Users\hengz> Add-AzureVirtualIP -ServiceName hwmvip -VirtualIPName vip2

    OperationDescription OperationId OperationStatus
    -------------------- ----------- ---------------
    Add-AzureVirtualIP f9014c8f-d72d-4bad-ae3d-2ffa28e24ce1 Succeeded

  2. 建立三組不同的SLB和LBS，分別用原有的VIP和新增加的VIP

PS C:\Users\hengz> Get-AzureVM -ServiceName hwmvip -Name hwmvip01 | Add-AzureEndpoint -Name myEndpoint01 -LoadBalancedEndpointSetName myLBSet01 -Protocol tcp -LocalPort 80 -PublicPort 80 -VirtualIPName vip1 -DefaultProbe | Update-AzureVM

OperationDescription OperationId OperationStatus
-------------------- ----------- ---------------

PS C:\Users\hengz> Get-AzureVM -ServiceName hwmvip -Name hwmvip02 | add-AzureEndpoint -Name myEndpoint00 -LBSetName myLBSet01 -Protocol tcp -LocalPort 80 -PublicPort 80 -DefaultProbe -VirtualIPName vip1 | Update-AzureVM

OperationDescription OperationId OperationStatus
-------------------- ----------- ---------------
Update-AzureVM fd406797-3d41-4b74-b030-40c5674e6364 Succeeded

PS C:\Users\hengz> Get-AzureVM -ServiceName hwmvip -Name hwmvip01 | add-AzureEndpoint -Name myEndpoint02 -LBSetName myLBSet02 -Protocol tcp -PublicPort 80 -LocalPort 81 -DefaultProbe | Update-AzureVM

PS C:\Users\hengz> Get-AzureVM -ServiceName hwmvip -Name hwmvip02 | add-AzureEndpoint -Name myEndpoint02 -LBSetName myLBSet02 -Protocol tcp -PublicPort 80 -LocalPort 81 -DefaultProbe | Update-AzureVM

OperationDescription OperationId OperationStatus
-------------------- ----------- ---------------
Update-AzureVM 57f7bcc3-b09e-482d-85f7-704c552c69f9 Succeeded

PS C:\Users\hengz> Get-AzureVM -ServiceName hwmvip -Name hwmvip02 | Add-AzureEndpoint -Name myEndpoint013 -LoadBalancedEndpointSetName myLBSet03 -Protocol tcp -LocalPort 82 -PublicPort 80 -VirtualIPName vip2 -DefaultProbe | Update-AzureVM

3. 檢視配置情況：

PS C:\Users\hengz> $mvip = Get-AzureDeployment -ServiceName hwmvip

可以看到我們預期的配置在兩臺伺服器上實現了。兩臺伺服器各屬於3個不同的負載均衡組，三個負載均衡組各對應一個IP地址，對外發布的埠號都是80。

至此配置結束。
