Table 2. Multi-tenant Deployment Examples
Example Description
Manage infrastructure configuration only
in the default tenant
In this example, all infrastructure is centrally managed by IaaS administrators and
fabric administrators in the default tenant. The shared infrastructure resources are
assigned to the users in each tenant by using reservations.
Manage infrastructure configuration in
each tenant
In this scenario, each tenant manages its own infrastructure and has its own IaaS
administrators and fabric administrators. Each tenant can provide its own infrastructure
sources or can share a common infrastructure. Fabric administrators manage
reservations only for the users in their own tenant.
The following diagram shows a multi-tenant deployment with centrally managed infrastructure. The IaaS
administrator in the default tenant configures all infrastructure sources that are available for all tenants.
The IaaS administrator can organize the infrastructure into fabric groups according to type and intended
purpose. For example, a fabric group might contain all virtual resources, or all Tier One resources. The
fabric administrator for each group can allocate resources from their fabric groups. Although the fabric
administrators exist only in the default tenant, they can assign resources to business groups in any
tenant.
Note Some infrastructure tasks, such as importing virtual machines, can only be performed by a user
with both the fabric administrator and business group manager roles. These tasks might not be available
in a multi-tenant deployment with centrally managed infrastructure.
