Introduction to Custom Domain Names introduction
Cloud Manager’s UI lets you add a custom domain to identify your site with a unique, branded name in a self-service manner. Adobe Experience Manager as a Cloud Service is provisioned with a default domain name, ending in *.adobeaemcloud.com. This default domain name remains, even after you associate custom domain names to your website.
What are Custom Domain Names? what-are-custom-domain-names
Each website has a unique, machine-readable, numerical address associated with it such as 184.33.123.64. The Domain Name System (DNS) is what lets you have custom, branded domains attached to websites by translating numerical addresses into memorable addresses such as wknd.com.
It is good practices to have a domain name for your site that is memorable for your customers and reflects your brand.
You can buy a domain name from a domain name registrar, a company or organization managing and selling domain names. Domain name registrars manage domain names on DNS servers.
Custom Domain Names and BYO CDNs byo-cdn
AEM as a Cloud Service offers a built-in content delivery network (CDN) service, but also lets you bring-your-own (BYO) CDN to use with AEM. Custom domains can be installed either in the AEM-managed CDN or a CDN you manage.
- Custom domain names (and certificates) that are installed in the AEM-managed CDN are managed via Cloud Manager.
- Custom domain names (and certificates) that are installed in your own CDN are managed in that specific CDN.
Domains managed in your own CDN do not need to be installed by way of Cloud Manager. They are made available to AEM by way of X-Forwarded-Host and match the vhosts defined in the Dispatcher. See the CDN documentation.
In one environment you can have both domains installed in the AEM-managed CDN and installed in your own CDN.
Workflow workflow
Adding a custom domain name requires interaction between the DNS service and Cloud Manager. Because of this there are several steps required to install, configure,and verify custom domain names. The following table gives an overview of the steps required, including what to do when common errors occur.

There are several limitations to using custom domain names with AEMaaCS.
- Custom domain names are supported in Cloud Manager for both publish and preview services for Sites programs. Custom domains for author services are not supported.
- Each Cloud Manager environment can host up to a maximum of 500 custom domains per environment.
- Domain namescannot be added to environments while there is a current running pipeline attached to those environments.
- The same domain namecannot be used on more than one environment.
- Only one domain name can be added at a time.
- AEM as a Cloud Service does not support wildcard domains such as
*.example.com. - Before adding a custom domain name, a valid SSL certificate that contains the custom domain name (wildcard certificates are valid) must be installed for your program. See Adding an SSL Certificate to learn more.
