Install a cloud distribution point for Configuration Manager
Applies to: Configuration Manager (current branch)
The implementation for sharing content from Azure has changed. Use a content-enabled cloud management gateway by enabling the option to Allow CMG to function as a cloud distribution point and serve content from Azure storage. For more information, see Modify a CMG.
Starting in version 2107, you can't create a traditional cloud distribution point (CDP).
This article details the steps to install a Configuration Manager cloud distribution point in Microsoft Azure. It includes the following sections:
- Before you begin
- Set up
- Configure DNS
- Set up site server proxy
- Distribute content and configure clients
- Manage and monitor
- Advanced troubleshooting
Before you begin
Start by reading the article Use a cloud distribution point. That article helps you plan and design your cloud distribution points.
Use the following checklist to make sure you have the necessary information and prerequisites to create a cloud distribution point:
The site server can connect to Azure. If your network uses a proxy, configure the site system role.
The Azure environment to use. For example, the Azure Public Cloud or the Azure US Government Cloud.
Use the Azure Resource Manager deployment. It has the following requirements:
Integration with Azure Active Directory for Cloud Management. Azure AD user discovery isn't required.
The Azure Subscription ID.
The Azure Resource Group.
A subscription admin account needs to sign in during the wizard.
A server authentication certificate, exported as a .PFX file.
A globally unique service name for the cloud distribution point.
Before requesting the server authentication certificate that uses this service name, confirm that the desired Azure domain name is unique. For example, WallaceFalls.CloudApp.Net.
- Sign in to the Azure portal.
- Select All resources, and then select Add.
- Search for Cloud service. Select Create.
- In the DNS name field, type the prefix you want, for example WallaceFalls. The interface reflects whether the domain name is available or already in use by another service.
Don't create the service in the portal, just use this process to check the name availability.
The Azure region for this deployment.
To enable a cloud distribution point to use Windows BranchCache, install the BranchCache feature on the site server.
If the site server has an on-premises distribution point site system role, configure the option in that role's properties to Enable and configure BranchCache. For more information, see Configure a distribution point.
If the site server doesn't have a distribution point role, install the BranchCache feature in Windows. For more information, see Install the BranchCache feature.
If you've already distributed content to a cloud distribution point, and then decide to enable BranchCache, first install the feature. Then redistribute the content to the cloud distribution point.
Starting in version 2107, this action isn't available. You can't create a traditional cloud distribution point (CDP). Use a content-enabled cloud management gateway by enabling the option to Allow CMG to function as a cloud distribution point and serve content from Azure storage. For more information, see Modify a CMG.
Perform this procedure on the site to host this cloud distribution point as determined by your design.
In the Configuration Manager console, go to the Administration workspace, expand Cloud Services, and select Cloud Distribution Points. In the ribbon, select Create Cloud Distribution Point.
On the General page of the Create Cloud Distribution Point Wizard, configure the following settings:
First specify the Azure environment.
Select Azure Resource Manager deployment as the deployment method. Select Sign in to authenticate with an Azure subscription admin account. The wizard auto-populates the remaining fields from the information stored during the Azure AD integration prerequisite. If you own multiple subscriptions, select the Subscription ID of the desired subscription to use.
Select Next. Wait as the site tests the connection to Azure.
On the Settings page, specify the following settings, and then select Next:
Region: Select the Azure region where you want to create the cloud distribution point.
Resource Group (Azure Resource Manager deployment method only)
Use existing: Select an existing resource group from the drop-down list.
Create new: Enter the new resource group name to create in your Azure subscription.
Primary site: Select the primary site to distribute content to this distribution point.
Certificate file: Select Browse and select the .PFX file for this cloud distribution point's server authentication certificate. The common name from this certificate populates the required Service FQDN and Service name fields.
The cloud distribution point server authentication certificate supports wildcards. If you use a wildcard certificate, replace the asterisk (
*) in the Service FQDN field with the desired hostname for the service.
On the Alerts page, set up storage quotas, transfer quotas, and at what percentage of these quotas you want Configuration Manager to generate alerts. Then select Next.
Complete the wizard.
The site starts to create a new hosted service for the cloud distribution point. After you close the wizard, monitor the installation progress of the cloud distribution point in the Configuration Manager console. Also monitor the CloudMgr.log file on the primary site server. If necessary, monitor the provisioning of the cloud service in the Azure portal.
It can take up to 30 minutes to provision a new distribution point in Azure. The CloudMgr.log file repeats the following message until the storage account is provisioned:
Waiting for check if container exists. Will check again in 10 seconds
After it provisions the storage account, the service is created and configured.
Verify that the cloud distribution point installation is complete by using the following methods:
In the Configuration Manager console, go to the Administration workspace. Expand Cloud Services, and select the Cloud Distribution Points node. Find the new cloud distribution point in the list. The Status column should be Ready.
In the Configuration Manager console, go to the Monitoring workspace. Expand System Status, and select the Component Status node. Show all messages from the SMS_CLOUD_SERVICES_MANAGER component, and look for status message ID 9409.
If necessary, go to the Azure portal. The Deployment for the cloud distribution point displays a status of Ready.
Before clients can use the cloud distribution point, they must be able to resolve the name of the cloud distribution point to an IP address that Azure manages. The management point gives them the Service FQDN of the cloud distribution point. The cloud distribution point exists in Azure as the Service name. See these values on the Settings tab of the cloud distribution point properties.
The Cloud Distribution Points node in the console includes a column named Service Name, but actually shows the Service FQDN value. To see both values, open Properties for the cloud distribution point and switch to the Settings tab.
The server authentication certificate common name should include your domain name. This name is required when you purchase a certificate from a public provider. It's recommended when issuing this certificate from your PKI. For example,
WallaceFalls.contoso.com. When you specify this certificate in the Create Cloud Distribution Point Wizard, the common name populates the Service FQDN property (
WallaceFalls.contoso.com). The Service name takes the same hostname (
WallaceFalls) and appends it to the Azure domain name,
cloudapp.net. In this scenario, clients need to resolve your domain's Service FQDN (
WallaceFalls.contoso.com) to the Azure Service name (
WallaceFalls.cloudapp.net). Create a CNAME alias to map these names.
Create CNAME alias
Create a canonical name record (CNAME) in your organization's public, internet-facing DNS. This record creates an alias for the cloud distribution point's Service FQDN property that clients receive, to the Azure Service name. For example, create a new CNAME record for
Client name resolution process
The following process shows how a client resolves the name of the cloud distribution point:
The client gets the Service FQDN of the cloud distribution point in the list of content sources. For example,
It queries DNS, which resolves the Service FQDN using the CNAME alias to the Azure Service name. For example,
It queries DNS again, which resolves the Azure service name to the Azure public IP address.
The client uses this IP address to start communication with the cloud distribution point.
The cloud distribution point presents the server authentication certificate to the client. The client uses the trust chain of the certificate to validate.
Set up site server proxy
The primary site server that manages the cloud distribution point needs to communicate with Azure. If your organization uses a proxy server to control internet access, configure the primary site server to use this proxy.
For more information, see Proxy server support.
Distribute content and configure clients
Distribute content to the cloud distribution point the same as any other on-premises distribution point. The management point doesn't include the cloud distribution point in the list of content locations unless it has the content that clients request. For more information, see Distribute and manage content.
Manage a cloud distribution point the same as any other on-premises distribution point. These actions include assigning it to a distribution point group, and managing content packages. For more information, see Install and configure distribution points.
Default client settings automatically enable clients to use cloud distribution points. Control access to all cloud distribution points in your hierarchy with the following client setting:
In the Cloud Settings group, modify the setting Allow access to cloud distribution points.
By default, this setting is set to Yes.
Modify and deploy this setting for both users and devices.
Manage and monitor
Monitor content that you distribute to a cloud distribution point the same as with any other on-premises distribution points. For more information, see Monitor content.
When you view the list of cloud distribution points in the console, you can add additional columns to the list. For example, the Data egress column shows the amount of data clients downloaded from the service in the last 30 days.
Configuration Manager periodically checks the Azure service. If the service isn't active, or if there are subscription or certificate issues, Configuration Manager raises an alert.
Configure thresholds for the amount of data that you want to store on the cloud distribution point, and for the amount of data that clients download from the distribution point. Use alerts for these thresholds to help you decide when to stop or delete the cloud service, adjust the content that you store on the cloud distribution point, or modify which clients can use the service.
Storage alert threshold: The storage alert threshold sets an upper limit in GB on the amount of data or content that you want store on the cloud distribution point. By default, this threshold is 2,000 GB. Configuration Manager generates warning and critical alerts when the remaining free space reaches the levels that you specify. By default, these alerts occur at 50% and 90% of the threshold.
Monthly transfer alert threshold: The monthly transfer alert threshold helps you to monitor the amount of content that transfers from the distribution point to clients for a 30-day period. By default, this threshold is 10,000 GB. The site raises warning and critical alerts when transfers reach values that you define. By default, these alerts occur at 50% and 90% of the threshold.
Configuration Manager monitors the transfer of data, but does not stop the transfer of data beyond the specified transfer alert threshold.
Specify thresholds for each cloud distribution point during installation, or use the Alerts tab of the cloud distribution point properties.
Alerts for a cloud distribution point depend on usage statistics from Azure, which can take up to 24 hours to become available. For more information about Storage Analytics for Azure, see Storage Analytics.
In an hourly cycle, the primary site that monitors the cloud distribution point downloads transaction data from Azure. It stores this transaction data in the
CloudDP-<ServiceName>.log file on the site server. Configuration Manager then evaluates this information against the storage and transfer quotas for each cloud distribution point. When the transfer of data reaches or exceeds the specified volume for either warnings or critical alerts, Configuration Manager generates the appropriate alert.
Because the site downloads information about data transfers from Azure every hour, the usage might exceed a warning or critical threshold before Configuration Manager can access the data and raise an alert.
View high-level information about the distribution point in the Cloud Distribution Points node under Cloud Services in the Administration workspace of the Configuration Manager console. Select a distribution point and select Properties to see more details.
When you edit the properties of a cloud distribution point, the following tabs include settings to edit:
Certificate file: Before the server authentication certificate expires, issue a new certificate with the same common name. Then add the new certificate here for the service to start using. If the certificate expires, clients won't trust and use the service.
Adjust the data thresholds for storage and monthly transfer alerts.
Manage content the same as for an on-premises distribution point.
Redeploy the service
More significant changes, such as the following configurations, require redeploying the service:
- Classic deployment method to Azure Resource Manager
- Service name
- Private to public PKI
- Azure region
If you have an existing cloud distribution point on the classic deployment method, in order to use the Azure Resource Manager deployment method you need to deploy a new cloud distribution point. There are two options:
If you want to reuse the same service name:
First delete the classic cloud distribution point. If there isn't another cloud distribution point, then clients may not be able to get content.
Create a new cloud distribution point using a Resource Manager deployment. Reuse the same server authentication certificate.
Distribute the necessary software package content to the new cloud distribution point.
If you want to use a new service name:
Create a new cloud distribution point using a Resource Manager deployment. Use a new server authentication certificate.
Distribute the necessary software package content to the new cloud distribution point.
Delete the classic cloud distribution point.
To determine the current deployment model of a cloud distribution point:
- In the Configuration Manager console, go to the Administration workspace, expand Cloud Services, and select the Cloud Distribution Points node.
- Add the Deployment Model attribute as a column to the list view. For a Resource Manager deployment, this attribute is Azure Resource Manager.
Stop or start the cloud service on demand
Stop a cloud distribution point at any time in the Configuration Manager console. This action immediately prevents clients from downloading additional content from the service. Restart the cloud service from the Configuration Manager console to restore access for clients. For example, stop a cloud service when it reaches a data threshold.
When you stop a cloud distribution point, the cloud service doesn't delete the content from the storage account. It also doesn't prevent the site server from transferring additional content to the cloud distribution point. The management point still returns the cloud distribution point to clients as a valid content source.
Use the following procedure to stop a cloud distribution point:
In the Configuration Manager console, go to the Administration workspace. Expand Cloud Services, and select the Cloud Distribution Points node.
Select the cloud distribution point. To stop the cloud service that runs in Azure, select Stop service in the ribbon.
Select Start service to restart the cloud distribution point.
Delete a cloud distribution point
To uninstall a cloud distribution point, select the distribution point in the Configuration Manager console, and then select Delete.
When you delete a cloud distribution point from a hierarchy, Configuration Manager removes the content from the cloud service in Azure.
Manually removing any components in Azure causes the system to be inconsistent. This state leaves orphaned information, and unexpected behaviors may occur.
If you need to collect diagnostic logging from the Azure VMs to help troubleshoot problems with your cloud distribution point, use the following PowerShell sample to enable the service diagnostic extension for the subscription:
# Change these variables for your Azure environment. The current values are provided as examples. You can find the values for these from the Azure portal. $storage_name="4780E3836835850223C071" # The name of the storage account that goes with the CloudDP $key="3jSyvMssuTyAyj5jWHKtf2bV5JF^aDN%z%2g*RImGK8R4vcu3PE07!P7CKTbZhT1Sxd3l^t69R8Cpsdl1xhlhZtl" # The storage access key from the Storage Account view $service_name="4780E3836835850223C071" # The name of the cloud service for the CloudDP, which for a Cloud DP is the same as the storage name $azureSubscriptionName="8ba1cb83-84a2-457e-bd37-f78d2dd371ee" # The subscription name the tenant is using $subscriptionId="8ba1cb83-84a2-457e-bd37-f78d2dd371ee" # The subscription ID the tenant is using # This variable is the path to the config file on the local computer. $public_config="F:\PowerShellDiagFile\diagnostics.wadcfgx" # These variables are for the Azure management certificate.
