```text
-ResourceGroupName "RG-Automation" `
-AutomationAccountName "Automation01"

View update deployments
Get-AzAutomationSoftwareUpdateRun `
-ResourceGroupName "RG-Automation" `
-AutomationAccountName "Automation01"

## Extension Ecosystem
### Installing Extensions

```powershell
## Install extensions via Windows Admin Center UI:

## Settings → Extensions → Available extensions

## Popular extensions:

## - Active Directory: Domain controller management

## - DHCP: DHCP server management

## - DNS: DNS server management

## - Storage Replica: Storage Replica management

## - System Insights: Predictive analytics

## - Security (Azure): Security Center integration

## View installed extensions
Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\ServerManagementGateway\Extensions\*" |
```text
Select-Object PSChildName, Version

## Developing Custom Extensions
```powershell

## Windows Admin Center SDK for custom extensions

## https://aka.ms/wacsdk

## Install Node.js and npm

## Install Windows Admin Center CLI
npm install -g windows-admin-center-cli

## Create new extension
wac create --company Contoso --tool CustomTool

## Build extension
cd CustomTool
npm install
npm run build

## Package extension
npm run package

## Upload to Windows Admin Center

## Settings → Extensions → Sideload extension → Upload .nupkg file
Expected output:
added 245 packages in 8s
found 0 vulnerabilities

Remote Management Capabilities
Browser-Based Access

## Windows Admin Center accessible from any device with web browser:

## - Windows (Chrome, Edge, Firefox)

## - macOS (Chrome, Safari, Firefox)

## - Linux (Chrome, Firefox)

## - iOS/Android (mobile browsers with limited functionality)

## Configure external access via reverse proxy or Azure AD Application Proxy

## Example: Configure IIS reverse proxy
Install-WindowsFeature Web-Server, Web-WebSockets, Web-Asp-Net45 -IncludeManagementTools

## Install URL Rewrite and Application Request Routing modules

## Configure reverse proxy rules in IIS for external access

Certificate Management

## Use trusted SSL certificate for production

## Generate CSR
$cert = New-SelfSignedCertificate -DnsName "wac.contoso.com" `
```powershell
-CertStoreLocation "cert:\LocalMachine\My" `
-KeyLength 2048 `
-KeyExportPolicy Exportable `
-NotAfter (Get-Date).AddYears(2)

Export CSR (submit to CA)
$csrPath = "C:\Certs\wac-csr.txt"
certreq -new -f -q "$env:TEMP\wac-request.inf" $csrPath

After receiving certificate from CA, import and bind to Windows Admin Center
$pfxPath = "C:\Certs\wac.contoso.com.pfx"
$pfxPassword = ConvertTo-SecureString "P@ssw0rd123!" -AsPlainText -Force
$cert = Import-PfxCertificate -FilePath $pfxPath `
-CertStoreLocation "Cert:\LocalMachine\My" `
-Password $pfxPassword

Update Windows Admin Center to use new certificate

Settings → Gateway → Use this certificate → Select certificate

## Multi-Server Sessions
```powershell

## Windows Admin Center supports multiple concurrent server connections

## Open multiple browser tabs for different servers

## Each tab maintains independent session

## Or use Server Manager extension for consolidated view of multiple servers

Hybrid Cloud Scenarios
Azure Arc-Enabled Servers

## Onboard on-premises servers to Azure Arc

## Install Azure Arc agent
$tenant = "YOUR_TENANT_ID"
$subscription = "YOUR_SUBSCRIPTION_ID"
$resourceGroup = "RG-HybridServers"
$location = "eastus"

$servers = "server1", "server2", "server3"
foreach ($server in $servers) {
```powershell
Invoke-Command -ComputerName $server -ScriptBlock {
param($tid, $sid, $rg, $loc)
# Download Arc agent
Invoke-WebRequest -Uri "https://aka.ms/AzureConnectedMachineAgent" -OutFile "$env:TEMP\AzureConnectedMachineAgent.msi"
# Install agent
msiexec /i "$env:TEMP\AzureConnectedMachineAgent.msi" /qn
# Connect to Azure
& "$env:ProgramW6432\AzureConnectedMachineAgent\azcmagent.exe" connect `
--tenant-id $tid `
--subscription-id $sid `
--resource-group $rg `
--location $loc `
--cloud "AzureCloud"
} -ArgumentList $tenant, $subscription, $resourceGroup, $location```
}
## Manage Arc-enabled servers from Windows Admin Center

## Azure Arc extension provides unified management

Unified Monitoring Across Environments
Figure: Azure Monitor Logs – KQL query results with time-series visualization.

## Use Azure Monitor to monitor both Azure and on-premises servers

## Query logs across all servers
$workspaceId = "YOUR_WORKSPACE_ID"

## Example query using Azure Monitor Logs
$query = @"
Perf
| where TimeGenerated > ago(1h)
| where ObjectName == "Processor" and CounterName == "% Processor Time"
| summarize AvgCPU = avg(CounterValue) by Computer
| order by AvgCPU desc
"@

## Execute query
Invoke-AzOperationalInsightsQuery -WorkspaceId $workspaceId -Query $query

Disaster Recovery with Azure Site Recovery
Architecture Overview: 

Architecture Decision and Tradeoffs
When designing server infrastructure solutions with Windows Server, consider these key architectural trade-offs:
| Approach | Best For | Tradeoff |
|---|---|---|
| Managed / platform service | Rapid delivery, reduced ops burden | Less customisation, potential vendor lock-in |
| Custom / self-hosted | Full control, advanced tuning | Higher operational overhead and cost |
Recommendation: Start with the managed approach for most workloads and move to custom only when specific requirements demand it.
Validation and Versioning
- Last validated: April 2026
- Validate examples against your tenant, region, and SKU constraints before production rollout.
- Keep module, CLI, and SDK versions pinned in automation pipelines and review quarterly.
Security and Governance Considerations
- Apply least-privilege access using RBAC roles and just-in-time elevation for admin tasks.
- Store secrets in managed secret stores and avoid embedding credentials in scripts or source files.
- Enable audit logging, data protection policies, and periodic access reviews for regulated workloads.
Cost and Performance Notes
- Define budgets and alerts, then monitor usage and cost trends continuously after go-live.
- Baseline performance with synthetic and real-user checks before and after major changes.
- Scale resources with measured thresholds and revisit sizing after usage pattern changes.
