Step 3: Configure Azure virtual machines by using virtual machine extensions
We will install Windows Server Web Server role on the two Azure virtual machines you deployed in the previous task by using the Custom Script virtual machine extension.
In the Azure portal, search for and select Storage accounts and, on the Storage accounts blade, click the entry representing the diagnostics storage account you created in the previous task.
On the storage account blade, click Containers and then click + Container.
| Setting | Value |
|---|---|
| Name | scripts |
| Public access level | Private (no anonymous access) |
Upload file from https://github.com/MicrosoftLearning/AZ-104-MicrosoftAzureAdministrator/tree/master/Allfiles/Labs/08/az104-08-install_IIS.ps1
In the Azure portal, search for and select Virtual machines and, on the Virtual machines blade, click az104-08-vm0. On the az104-08-vm0 virtual machine blade, in the Settings section, click Extensions, and the click + Add. On the New resource blade, click Custom Script Extension and then click Create.
On the Storage accounts blade, click the name of the storage account into which you uploaded the az104-08-install_IIS.ps1 script, on the Containers blade, click scripts, on the scripts blade, click az104-08-install_IIS.ps1, and then click Select.
On the az104-08-vm1 blade, in the Settings section, click Export template. On the az104-08-vm1 - Export template blade, click Deploy. On the Custom deployment blade, click Edit template. On the Edit template blade, in the section displaying the content of the template, insert the following code
{
"type": "Microsoft.Compute/virtualMachines/extensions",
"name": "az104-08-vm1/customScriptExtension",
"apiVersion": "2018-06-01",
"location": "[resourceGroup().location]",

}
}
}, 
On the Run Command Script blade, type the following and click Run to access the web site hosted on az104-08-vm0:
Invoke-WebRequest -URI http://10.80.0.5 to access the web site hosted on az104-08-vm1.Step 3 : Scale compute and storage for Azure virtual machines
We will scale compute for Azure virtual machines by changing their size and scale their storage by attaching and configuring their data disks.
On the az104-08-vm0 virtual machine blade, click Size and set the virtual machine size to Standard DS1_v2 and click Resize
On the az104-08-vm0 virtual machine blade, click Disks, Under Data disks click + Create and attach a new disk.

Also it can be resized in the following process
On the az104-08-vm1 - Export template blade, click Deploy. On the Custom deployment blade, click Edit template. On the Edit template blade, in the section displaying the content of the template, replace the line 30
"vmSize": "Standard_D2s_v3" with the following line):"vmSize": "Standard_DS1_v2"
On the Edit template blade, in the section displaying the content of the template, replace line 49 (
"dataDisks": [ ] line) with the following code :"dataDisks": [ { "lun": 0, "name": "az104-08-vm1-datadisk0", "diskSizeGB": "1024", "caching": "ReadOnly", "createOption": "Empty" }, { "lun": 1, "name": "az104-08-vm1-datadisk1", "diskSizeGB": "1024", "caching": "ReadOnly", "createOption": "Empty" } ]
Also we can deploy zone-resilient Azure virtual machine scale sets by using the Azure portal
| Setting | Value |
|---|---|
| Subscription | the name of the Azure subscription you are using in this lab |
| Resource group | the name of a new resource group az104-08-rg02 |
| Virtual machine scale set name | az10408vmss0 |
| Region | select one of the regions that support availability zones and where you can provision Azure virtual machines different from the one you used to deploy virtual machines earlier in this lab |
| Availability zone | Zones 1, 2, 3 |

Scale compute and storage for Azure virtual machine scale sets
On the az10408vmss0 - Scaling blade, select the Custom autoscale option and configure autoscale with the following settings (leave others with their default values):
| Setting | Value |
|---|---|
| Scale mode | Scale based on a metric |
Click the + Add a rule link and, on the Scale rule blade, specify the following settings (leave others with their default values):
| Setting | Value |
|---|---|
| Metric source | Current resource (az10480vmss0) |
| Time aggregation | Average |
| Metric namespace | Virtual Machine Host |
| Metric name | Network In Total |
| Operator | Greater than |
| Metric threshold to trigger scale action | 10 |
| Duration (in minutes) | 1 |
| Time grain statistic | Average |
| Operation | Increase count by |
| Instance count | 1 |
| Cool down (minutes) | 5 |
Command for clean up : Get-AzResourceGroup -Name 'az104-08*' | Remove-AzResourceGroup -Force -AsJobSetting Value Instance limits Minimum 1 Instance limits Maximum 3 Instance limits Default 1
