Before you deploy Cloud Foundation, or before you create or expand a workload domain, you must define the hostnames and IP addresses for various system components.
Most of the defined hostnames and IP addresses need to exist in DNS and be resolvable, through forward and reverse lookups.
The hostnames and IP addresses required are categorized as follows:
- External services: Services that are external to the Cloud Foundation solution and are required for proper operation.
- Virtual infrastructure layer: Components that provide for the basic foundation of the solution.
- Operations management layer: Components used for day-to-day management of the environment, for example, vRealize Operations.
- Cloud management layer: Services that consume the infrastructure layer resources, for example, vRealize Automation.
