After you create the VMware Cloud Director server group, you can install a Cassandra database. If you are using a PostgreSQL database, you can configure SSL and adjust some parameters on the database.

Service providers and tenants can use the VMware Cloud Director API to test connections to remote servers, and to verify the server identity as part of an SSL handshake. To protect VMware Cloud Director network connections, configure a deny list of internal hosts that are unreachable to tenants who are using the VMware Cloud Director API for connection testing. Configure the deny list after the VMware Cloud Director installation or upgrade and before granting tenants access to VMware Cloud Director. See Configure a Test Connection Denylist.
