The diagram in the Scope section of this use case shows how VMware Cloud 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 required 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. VMware Cloud Director integrates with NSX Manager to create isolated layer 2 tenant networks. Tier-1 gateways allow tenants to route traffic between their tenant networks.
