The diagram in the Scope section of this use case shows how vCloud Director Compute Cluster, Organization, Organization VDC, NSX-T Data Center segments, and Tier-1 gateways can be used to provide a multitenant environment for VNF deployments. The Edge Pod hosts the NSX-T Data Center Tier-0 gateways that are used as provider routers for external network connectivity. The NSX Manager provisions the Tier-0 gateway and other networking components needed for organization VDCs such as segment (East-West) and segment (North-South) connecting to Tier-1 gateway. NSX Manager also creates the Tenant Tier-1 gateway.
The CSP can map a vSphere compute cluster to a Provider VDC, then for each tenant the CSP can allocate and reserve resources by using organization-based constructs. Every organization VDC is associated with a resource pool within the compute cluster for resource guarantee.
The separation of network access between organizations is important for multitenancy. vCloud Director integrates with NSX Manager to create isolated layer 2 tenant networks. Tier-1 gateways allow tenants to route traffic between their tenant networks.
