Components

The Resource Pod provides the runtime environment for the network functions. The section covers the logical tenancy and networking components.

Provider VDC

The Provider Virtual Data Center (VDC) is a standard container for a pool of compute, storage, and network resources from a single vCenter Server instance. During the deployment, a VNF can use one or more Provider VDCs per site, or multiple VNFs can share a single Provider VDC with different organization VDCs. The requirements of each VNF are assessed as part of the onboarding process.

Organization

Organizations are the unit of multi-tenancy within VMware Cloud Director. A tenant can be defined in multiple ways in the Telco Cloud Infrastructure platform. A tenant can, for example, be a VNF provider, but it can also be defined per Telco application consisting of multiple VNF providers who provide a joint service. The necessary level of separation between different VNFs and the creation of tenants should be identified during the onboarding process.

Organization VDCs

An organization VDC is a subgroup of compute, storage, and network resources that are allocated from a Provider VDC and mapped to an organization. Multiple organization VDCs can share the resources of the same Provider VDC. An organization VDC is the environment where VNF workloads are deployed and executed.

Quotas on organizations set limits on the VMware Cloud Director tenant resources. Organization VDCs allow providing resource guarantees for workloads from the resource quota available to the organization and avoid noisy neighbor scenarios in a multitenant environment.

vApps

A vApp is a container for multiple VMs and the standard unit for workloads in VMware Cloud Director. vApps contain one or more VMs and networks and can be imported or exported as an OVF file. In the Telco Cloud Infrastructure platform, a VNF instance can be a vApp.
