Host names and IP addresses for external services
External services such as Active Directory (AD) and NTP must be accessible and resolvable by IP Address and Fully Qualified Domain
Name (FQDN). Acquire the hostnames and IP addresses for AD and NTP before deploying Cloud Foundation.
Allocate hostnames and IP addresses to the following components:
• NTP
• AD
• DNS
• Certificate Authority (CA)
The following table provides sample information for the external services. This example uses a DNS domain called osevcf17.local for
illustration purposes. Modify the sample information to conform to the configuration of your site.

Host names and IP addresses for the virtual infrastructure
layer
Most of the virtual infrastructure components that are installed by Cloud Foundation require their hostnames and IP addresses to be
defined before deployment.
During the initial deployment of Cloud Foundation, the management domain is created and you must define components specific to the
management domain before installation.
After the initial deployment, additional workload domains are created and you must define components specific to each additional workload
domain.
Planning ahead for the initial deployment and the workload domains to be created avoids delays in deployment.
The following table provides an example of the information for the virtual infrastructure layer using the standard deployment model with a
single workload domain. This example uses a DNS domain called osevcf17.local for illustration purposes. Modify the sample
information to conform to the configuration of your site.
