A newly created organization VDC has no networks in it. After a system administrator has created the required network infrastructure, an organization administrator can create and manage most types of organization VDC networks.After a Virtual Infrastructure Administrator creates a VDC, a Virtual Infrastructure Administrator or Network Administrator can create and manage organization VDC networks.
An organization VDC can be provisioned with zero or more networks. These organization VDC networks can be configured to provide direct or routed connections to external networks, or can be isolated from external networks and other organization VDC networks. Routed connections require an Edge Gateway and network pool in the VDC. The Edge Gateway provides firewall, network address translation, static routing, VPN, and load balancing services. An organization VDC can be provisioned with zero or more networks. These organization VDC networks can be configured to provide routed connections to external networks, or can be isolated from external networks and other organization VDC networks.
In addition to the network operations enabled by the VMware Cloud Director API, you can use the VMware Cloud Director API for NSX for advanced networking operations. See the VMware Cloud Director API for NSX Programming Guide.
