By default, you access APEX components as well as your developed APEX apps and REST endpoints 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. Once 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 APEX database as the backend. Your APEX database must be configured with a private endpoint in same VCN.
