4.1. DNS Names

The Azure option in the Cogent DataHub^™ service for Azure accessible from Remote Config lets user-administrators of the service configure DNS names and firewall rules.

4.1. DNS Names

Here you can configure DNS names that will allow users to access the system with an alternate DNS name that you specify using your own DNS servers. When you create a DataHub for Azure deployment, Microsoft creates a server with a host name that is not particularly user-friendly, such as skkynetdemo2-93468441fe4f.eastus.cloudapp.azure.com. Choosing your own DNS name can better represent your company, product or solution, as well as being easier to remember and type.

Enabling DNS name support on your DataHub for Azure requires two steps:

Use your DNS server to create a CNAME record for the desired alternate name, routing it to the host name created by Microsoft for your DataHub for Azure service.
Use Remote Config to connect to your DataHub for Azure service and add the alternate DNS name to the certificate that the DataHub instance generates that supports SSL web server traffic.

The Add and Edit buttons open a dialog where you can add a DNS name, or edit the one currently selected. The Remove button removes the selected DNS name.

Dry run mode: Checking this box means that the current certificate will not be replaced. This is useful for testing certificate creation. The certificate creation tool limits the number of certificates that can be generated to a maximum of five per week. This option lets you test certificate creation without risking exceeding the limit. Once you confirm everything is correct, uncheck the checkbox and click Apply to generate and deploy the production certificate. Then re-check the box and click Apply again. This will help avoid accidentally creating another certificate.
Status: Displays the current status of user interactions with the system. When you click Apply to create a certificate, the results will be displayed in the Status area. Review the messages to confirm the required DNS names have been correctly added to the certificate as alternates.
Certificate Viewer: Lists details about the certificate. Review the Subject Alternative Names to confirm the certificate includes the alternates DNS names you require.
