Move-AzureDeployment花費太長時間來交換服務器？

Question

我試圖通過在PowerShell中運行它來使用Move-AzureDeployment cmdlet交換服務器。它似乎需要大約4分鐘才能從分期轉換到生產。這就是4分鐘的停機時間，並不是真的可以接受。當我從Azure Portal手動交換服務器時，它幾乎是瞬間發生的。

我想知道爲什麼它需要更長的時間使用cmdlet，我該怎麼做才能解決此問題，因爲我希望能夠使用powershell交換我的分段和生產服務器。

這裏是我的PowerShell腳本：

try 
{ 
$ErrorActionPreference = "stop" 

Write-Host "Deploying build build no. $env:build_number to $_serviceName" 

#import azure cmdlets module 
Write-Host "Importing azure service management modules (i.e for the old portal)" 
Import-Module "C:\Program Files (x86)\Microsoft SDKs\Azure\PowerShell\ServiceManagement\Azure\Azure.psd1" 

Write-Host "Started Command for Switching Slots" 
#Switch slots from Staging to Production 
Move-AzureDeployment -ServiceName $_serviceName 
Write-Host "Finished Command for Switching Slots" 


#make sure deployment is in running state 
$deployment = Get-AzureDeployment -servicename $_serviceName -slot $_slotName 
Write-Host "$_serviceName is in state $($deployment.status)" 
$StopWatch = [System.Diagnostics.Stopwatch]::StartNew() #declare stopwatch 
while (($deployment.Status -ne "running") -and ($StopWatch.Elapsed.Hours -lt 2)) #running the loop for a maximum of 2 hours 
{ 
    Write-Host "wait 5 seconds before trying again" 
    Start-Sleep -s 5 
    $deployment = Get-AzureDeployment -servicename $_serviceName -slot $_slotName 
    Write-Host "$_serviceName is in state $($deployment.status)"   
} 

#make sure all roles are in ready state 
$nonReadyInstances = (Get-AzureDeployment $_serviceName -Slot $_slotName).RoleInstanceList | Where-Object { $_.InstanceStatus -ne "ReadyRole" } | ft -Property RoleName, InstanceName, InstanceStatus 
$nonReadyInstances 
$StopWatch = [System.Diagnostics.Stopwatch]::StartNew() #declare stopwatch 
while (($nonReadyInstances -ne $null) -and ($StopWatch.Elapsed.Hours -lt 2)) #running the loop for a maximum of 2 hours 
{ 
    Write-Host "wait 5 seconds before trying again" 
    Start-Sleep -s 5 
    $nonReadyInstances = (Get-AzureDeployment $_serviceName -Slot $_slotName).RoleInstanceList | Where-Object { $_.InstanceStatus -ne "ReadyRole" } 
    $nonReadyInstances 
} 

#output deployment id 
#$deploymentid = Check-Deployment -serviceName $_serviceName -slotName $_slotName 
#Write-Host "Deployed to $_serviceName with deployment id $deploymentid and slot $_slotName" 
    exit 0 

    } 
catch [System.Exception] 
    { 
Write-Host $_.Exception.ToString() 
exit 1 
}

從我的理解一個臨時插槽和生產之間的交換是VIP交換，因爲他們都在運行。微軟表示，你不應該在網站/應用程序本身上看到任何停機時間。請求仍然會打到舊的生產服務器，直到更改完成。在交換過程中您是否看到網站停機？
