The standard architecture model includes a dedicated management domain for all management components of Cloud Foundation. The management domain uses a minimum of four hosts and is created during the bring-up process.
User workloads run in virtual infrastructure (VI) workload domains. Thus, there is a separation between the management domain and user-created VI workload domains.
Standard architecture is recommended for Cloud Foundation deployments with seven or more hosts where four hosts are required for the management domain and three or more hosts are required for a VI workload domain.
