2. Azure AD DS Setup:


<h1>Enable Azure AD DS</h1>

az ad ds create --name "yourdomain.com" --resource-group "your-resource-group" --location "your-location"

3. Syncing On-Premise AD DS with Azure AD:


<h1>Install Azure AD Connect</h1>

msiexec /i AzureADConnect.msi

<h1>Configure synchronization</h1>

<h1>Follow the prompts to sync your on-premise AD with Azure AD</h1>

4. Managing Azure AD Users:

az ad user create --display-name "John Doe" --password "Password123" --user-principal-name "[email protected]"

<h1>List all users</h1>

az ad user list --output table

5. AD DS with Azure Virtual Machines:


<h1>Create a VM with AD DS</h1>

az vm create --resource-group "your-resource-group" --name "ad-vm" --image "Win2019Datacenter" --admin-username "adminuser" --admin-password "AdminPassword123" --size "Standard_DS2_v2"

<h1>Install AD DS on the VM</h1>

Invoke-Command -ComputerName "ad-vm" -ScriptBlock { Install-WindowsFeature -Name AD-Domain-Services -IncludeManagementTools }

6. AD RMS Configuration:


<h1>Install AD RMS role</h1>

Install-WindowsFeature -Name ADRMS -IncludeManagementTools

<h1>Configure AD RMS</h1>

Install-AdfsFarm -CertificateThumbprint "your-cert-thumbprint" -FederationServiceName "your-federation-service-name"

7. AD CS (Certificate Services) Setup:


<h1>Install AD CS role</h1>

Install-WindowsFeature -Name ADCS-Cert-Authority -IncludeManagementTools

<h1>Configure Certificate Authority</h1>

Install-AdcsCertificationAuthority -CACommonName "your-CA-name" -CAType "EnterpriseRootCA"

8. AD FS (Federation Services) Configuration:


<h1>Install AD FS role</h1>

Install-WindowsFeature -Name ADFS-Federation -IncludeManagementTools

<h1>Configure AD FS</h1>

Install-AdfsFarm -CertificateThumbprint "your-cert-thumbprint" -FederationServiceName "your-federation-service-name"

9. AD LDS (Lightweight Directory Services) Setup:


<h1>Install AD LDS role</h1>

Install-WindowsFeature -Name ADLDS -IncludeManagementTools

<h1>Configure AD LDS instance</h1>

dsdbutil /install "your-instance-name" /ldapport:389

What Undercode Say:

Understanding the differences between AD DS and Azure AD DS is crucial for making informed decisions about your organization’s infrastructure. AD DS is ideal for on-premise environments, offering full control and customization, while Azure AD DS provides a cloud-based solution with seamless integration with other Azure services. Both have their unique advantages and can be used in tandem to create a hybrid environment that leverages the strengths of both solutions. Always consider your organization’s specific needs, such as scalability, security, and compliance, when choosing between these services. For further reading, you can refer to the official Microsoft documentation on AD DS and Azure AD DS.
