The CSP can facilitate the NFV transformation on a shared resource infrastructure environment with multitenant consumption models. The design of those tenant environments is outlined in this section.
Scope Multitenancy defines the isolation of resources and networks to deliver applications with quality. Because multiple tenants share the resource infrastructure, secure multitenancy can be enabled by using VMware vCloud Director in a single cloud island and across distributed clouds. In addition to the built-in workload and resource optimization capabilities, predictive optimization can be enabled with analytics by using features such as vSphere DRS.
Design Objectives A unit of tenancy is called an Organization VDC within the scope of an Organization. It is defined as a composition of dedicated compute, storage, and network resources as well as workloads. The tenant is associated with a set of operational policies and SLAs. The tenant can be bound to a single Organization VDC or can be composed of many Organization VDCs. Services such as HSS and DNS are examples of shared tenancy.
