By default you access Oracle APEX apps, REST endpoints, and developer tools on Autonomous Database using the
oraclecloudapps.com domain name.
You can optionally configure a vanity URL or custom domain name that is easy to remember to
help promote your brand identity.
After you acquire a desired domain name and matching SSL certificate from a vendor of your choice, deploy an Oracle Cloud Infrastructure Load Balancer in your Virtual Cloud Network (VCN) using your Autonomous Database as the backend. Your Autonomous Database instance must be configured with a private endpoint in the same VCN. See Configuring Network Access with Private Endpoints for more information.
