You must provide a set of external services before you deploy the vRealize Suite 2019 and Workspace ONE Access components for this guidance. IP Subnets for the Application Virtual NetworksYou must allocate an IP subnet to each application virtual network and the management applications that are in this network. Host Names and IP AddressesBefore you deploy vRealize Suite 2019 and Workspace ONE Access, you must define the host names and IP addresses for each of the components. These host names must also be configured in DNS with fully qualified domain names (FQDN) that map the hosts to their IP addresses. Time SynchronizationSynchronized systems over NTP are essential. Consistent system clocks are important for the proper operation of the components in the SDDC. User Accounts and GroupsBefore you deploy and configure vRealize Suite 2019 and Workspace ONE Access on VMware Cloud Foundation, you must provide a specific configuration of Active Directory users and groups. You use these users and Active Directory groups for application login, for assigning roles, and for application-to-application authentication. Active Directory Computer ObjectsYou must create Active Directory computer objects for the Workspace ONE Access virtual appliances, so that they can join the Active Directory domain for connector operations. Additional Storage RequirementsFor vRealize Log Insight log archiving, you must provide supplemental storage.
