With the CMG set up via internal or external certs (see Parts 1 & 2),  we can now use cloud distribution points to get content to our external endpoints.

Three certificates are needed to set up the cloud DP, the client authentication certificate which we have already created in either part 1 or 2, an Azure management certificate  and a web server certificate for the cloud DP.  We can use the same technique for the cloud DP certificate creation as in the previous blogs but for completeness let’s run through that process again.

Creating the cloud DP management cert

The management certificate for the cloud DP service can be created in the same manner as in parts 1 and 2 of this series. However, for part 3 I thought I would show you another way that you can create a management certificate, this time using some PowerShell commands.

Type in the following command into an elevated PowerShell windows

$cert = New-SelfSignedCertificate -DnsName <yourdomain>.cloudapp.net -CertStoreLocation "cert:\LocalMachine\My"
$password = ConvertTo-SecureString -String "<your password>" -Force -AsPlainText
Export-PfxCertificate -Cert $cert -FilePath ".\CloudDP-ManagementCert.pfx" -Password $password
Export-Certificate -Type CERT -Cert $cert -FilePath .\CloudDP-ManagementCert.cer

As you can see this quickly generates a pfx and cer management certificate.

Right click the Web Server template and select Duplicate Template.

2017-11-18 23_00_53-Certificate Templates Console.jpg

Select Windows Server 2003 Enterprise. Click OK.

2017-11-13 20_51_04-Duplicate Template.jpg

Enter a name for the template. I’ve called mine ‘SCCMCMG – Management Certificate’ as I am going to create another template for my Web Server cert.

2017-11-13 20_52_03-Properties of New Template.jpg

In the Request Handling tab choose Allow private key to be exported.

2017-11-13 20_52_09-Properties of New Template.jpg

Set security accordingly so that enrollment can take place, Read and Enroll permissions are required for this.

2017-11-18 23_09_55-Properties of New Template.jpg

With the template in place, we need to issue it so that we can enroll with it.

To do this right click the Certificate Templates folder in the Certificate Authority and choose New>Certificate Template to Issue.

2017-11-13 20_53_09-certsrv - [Certification Authority (Local)_internal-DC-CA_Certificate Templates].jpg

Set up Azure for cloud DPs

As with the CMG we need to upload a managment certificate into Azure for the cloud service.

In the Azure Portal , navigate to Subscriptions and then select your subscription.

cmg-009.JPG

Select Management Certificates from the list of options.

cmg-003.JPG

Click the Upload link.

The cloud service information provided will be validated.

2017-11-17-20_18_16-validate-cloud-service-information.jpg

Note that Azure will automatically generate a GUID for the service name. Make a note of this GUID as we will need this later in the set-up. Click the Browse button.

2017-11-20 22_05_08-Create Cloud Distribution Point Wizard.jpg

Choose the cloud DP certificate file.

2017-11-20 22_07_12-Service Certificate.jpg

Enter the password for the .pfx and click OK.

2017-11-20 22_00_24-Password.jpg

Note that the service FQDN is automatically populated. We’ll need to map this address to the <Service name GUID>.cloudapp.net address shortly. Click Next.

2017-11-20 22_18_28-Create Cloud Distribution Point Wizard.jpg

Set any threshold alert levels for the cloud DP at this stage and click Next.

2017-11-20 22_21_20-Create Cloud Distribution Point Wizard.jpg

Click Next.

clouddp-011.jpg

Click Close to complete the set up wizard.

The cloud DP will be in a provisioning state. It can take a while to build the cloud DP

2017-11-20 22_22_57-System Center Configuration Manager (Connected to CMR - SCCM 2012 R12 - CMR Netw.jpg

The progress can be monitored in the CloudMgr.log file.

2017-11-20 22_24_10-Configuration Manager Trace Log Tool - [C__Program Files_Microsoft Configuration.jpg

When provisioning has completed the cloud DP will report as ready.

2017-11-20 22_41_56-System Center Configuration Manager (Connected to CMR - SCCM 2012 R12 - CMR Netw.jpg

Set up name resolution for the cloud DP

To resolve the cloud DP, you need to map the address of the service FDQN to the <service GUID>.cloudapp.net address.

So for my example, I need to create a CNAME record to cater for this.

clouddp-004.jpg

Upload content to the cloud DP

At this stage, our cloud DP is ready, configured and raring to go. We can upload content to it in the same way as we do any on-prem DP.

The finale – push software to a client connected via the CMG

So we’ve been building up to this point. We showed in parts 1 and 2 that we could connect clients to the SCCM environment via the CMG, which acts as a proxy to the internal MP and SUP. We need cloud DP since you cannot route internally to non-Internet facing DPs.

So as a test, I am going to publish a 7-Zip installation to the Internet connected client and install the software across the Internet

First up, I have confirmed that my client is still connected via the Internet – note the Domain joined client is in Internet in the ClientLocation.log

clouddp-005.JPG

A quick check and nothing is assigned to the device for software deployment.

clouddp-006.JPG

I then created an available deployment for 7-Zip targeted at my Internet based client and on the client ran a policy retrieval – all standard ConfigMgr tasks.

After policy had updated the Software Center showed 7-Zip as an available install.

clouddp-007.JPG

After kick starting the 7-Zip install, a quick glance at the CAS.log shows the download taking place, and from my cloud DP, sccmsolcloudp1.sccmsolutions.co.uk.

clouddp-008.JPG

and that the install succeeds.

clouddp-009.JPG

There’s a lot to take in with the new Cloud Management Gateway and it’s integration with cloud DP and internal MP and SUP. I have show how to get the services up and running but there are plenty of planning considerations that need to be examined prior to doing these installations.

I recommend that you read the following before deploying these services.

Plan for the cloud management gateway in Configuration Manager at https://docs.microsoft.com/en-us/sccm/core/clients/manage/plan-cloud-management-gateway
