VMware Cloud Director (VCD) was designed from the bottom up with multi-tenancy in thoughts. It’s a product that permits a number of prospects or tenants to make use of the VMware Software program-Outlined Knowledge Heart (SDDC) infrastructure whereas sustaining strict isolation, safety, and useful resource allocation.
VMware NSX has offered a multi-tenant data-plane mannequin because the starting of the product. Nonetheless, it began to assist administration aircraft multi-tenancy with the introduction of NSX Initiatives in model 4.0.1.1 (API) and in 4.1 within the UI.
Naturally, to enhance the combination with NSX and unlock numerous networking options, VCD growth advanced in order that the newest 10.5.1 launch now adopts the NSX Mutli-Tenancy mannequin. Learn extra about NSX Multi-Tenancy journey.
Ideas
Within the VCD platform, tenancy is carried out by using the Organizations. Every tenant is assigned a devoted group, offering a logically segregated digital infrastructure and assets for his or her workloads. The Group assemble permits for fine-grained management over the tenant’s entry to assets and allows the tenant to handle their very own Customers, Digital Knowledge Facilities (VDCs), Catalogs, Insurance policies, and extra.
To explicitly outline the tenant paradigm, VMware NSX carried out an answer known as Initiatives. These Initiatives delegate NSX customers to completely different areas with their very own objects, configurations, and monitoring (based mostly on alarms and logs).
VCD 10.5.1 offers administration capabilities related to NSX Tenancy, that are solely within the Supplier’s scope. The NSX Tenancy function is on the market per Group foundation, and when enabled, a VCD Group maps on to an NSX Undertaking.
After the NSX Tenancy is enabled on the Organizational degree, Suppliers can create Group Digital Knowledge Facilities (VDCs) with Networking Tenancy enabled by way of the Org. VDC creation wizard.
Any present VDCs and Knowledge Heart (DC) Teams owned by that Group are thought-about brownfield and have the Networking Tenancy “Inactive”.
It’s essential to notice that VCD can not acknowledge and import present NSX Initiatives. With a purpose to use Networking Tenancy inside the context of VCD, suppliers should first outline the Group inside VCD after which to allow the Networking Tenancy.
VCD Networking Tenancy Particulars
When a Supplier allows the NSX Tenancy (Networking Tenancy) for a selected Group, he also can outline a Log Identify. That is the Group’s distinctive identifier within the backing NSX Supervisor logs.
Activating the Networking Tenancy for the Group doesn’t set off speedy NSX Undertaking creation. As an alternative, the NSX Undertaking will get created when the primary Networking Tenancy enabled VDC is created. The NSX Undertaking title corresponds to the Group title, although.
By default, the Networking Tenancy for a VDC that’s created in an NSX Tenancy enabled Group is “ON”. When the Networking Tenancy is enabled for a specific VDC, the Community Pool choice is disabled. That’s as a result of NSX helps Undertaking creation solely within the default overlay Transport Zone.
The Community Pool with the default overlay Transport Zone for the backing community supplier has to exit beforehand. In any other case, VCD will throw an error when creating Networking Tenancy enabled VDC.
Not all VDCs in a Undertaking-aware group have to take part within the Undertaking. Suppose a unique Geneve-backed Community Pool (non-default Transport Zone) or solely VLAN networks are required in a VDC. In that case, the Supplier can disable the Networking Tenancy and choose the respective Community Pool.
Nonetheless, it’s important to notice that the Networking Tenancy (NSX Undertaking participation) can solely be specified throughout VDC creation. It can’t be modified afterward. Likewise, as soon as a Supplier allows the Networking Tenancy on VDC creation, they can’t swap Community Swimming pools.
VCD Mannequin to NSX Initiatives
VCD makes the NSX Undertaking administration capabilities, corresponding to creation, Tier-0 Gateway, and NSX Edge Cluster assignments, solely clear for each the Supplier and the Tenant. When an Edge Gateway is created in a Networking Tenancy enabled VDC, VMware Cloud Director takes care of the respective NSX Edge Cluster and Tier-0 Gateway to be shared with the Undertaking.
NSX segments related to exterior and imported networks don’t must be a part of the Undertaking. If mandatory, VCD takes care of those exterior parts to be related to Undertaking parts by way of an NSX Useful resource Share. When the connection is eliminated, the share is up to date accordingly.
Knowledge Heart Teams assist
The NSX Undertaking is solely owned by the Group that created it. The DC Group beginning VDC kind (Networking Tenancy enabled or not) determines whether or not the DC Group can have the Networking Tenancy lively. It’s not necessary for all VDC members of the DC Group to have an lively Networking Tenancy. VMware Cloud Director helps a blended mode the place a DC Group has each Networking Tenancy lively VDCs and Networking Tenancy inactive VDCs.
The NSX Undertaking related to the beginning VDC is the one which will likely be used for all DC Group networking and safety objects. Edge Gateways, Networks, Distributed Firewall Guidelines, Safety Teams, and so forth., will sit inside the scope of that NSX Undertaking.
Unsupported options
At present, NSX Initiatives isn’t a supported function for NSX Federation deployments. Additionally, not all Edge Gateway options can be found for Networking Tenancy enabled VDCs or DC Teams. VPNs (IPsec/L2) and sharing section profile templates are the principle notables.

In Conclusion
By matching the NSX Initiatives with VCD’s Tenancy, prospects will profit from a variety of networking capabilities the NSX Multi-tenancy answer offers. Considered one of these essential options is tenant-focused logging for core VCD networking providers corresponding to Edge Companies and Distributed firewalls.
At present, the principle platform for offering log entry inside VCD is VMware Aria Operations (a.okay.a. LogInsight). Aria Operations is a part of the bottom VMware Cloud Supplier Platform (VCPP) bundle and, subsequently, is on the market for all suppliers at no cost as a part of the VCPP program.
NSX Initiatives logs from the Distributed and Gateway firewalls are labeled with the NSX Undertaking log identifier, offering simple identification and separation per Tenant.
The combination with NSX Initiatives may also enable exploring the potential for function enhancements to offer tenant self-service login capabilities in VCD.
