Planning for Domain Name System UpdatesPlanning for Domain Name System Updates
To allow users to locate your web tier and optional load balancer, you must buy publicly resolvable names for these systems. Do the following:
-
Define a domain name, for example, mydomain.com
-
Define host names, for example, myhost.mydomain.com
-
Contact a Domain Name registrar, and register the domain name and associated host names.
Clients using Self-Service and risk-based authentication (RBA) must be able to resolve to the virtual host name using Domain Name System (DNS).
-
If your deployment has a load balancer, the virtual hostname must resolve to the public IP address of the load balancer.
-
If your deployment does not have a load balancer, the virtual hostname must resolve to the public IP addresses of each web tier.
