• All site collections for a single site subscription must reside in the same Web
application.
• Multiple site subscriptions can be hosted in a single Web application. Multiple
site subscriptions can share the same database.
• Administrators define which services are available and activated for each tenant.
The subscription ID for a tenant is used to map the service to the site collections.
• Multiple tenants can share service data. For example, multiple branches of an
organization can share profile data. In this case, the multiple branches share a
data partition within the profile service.
• Service data can be partitioned for each tenant, ensuring that customer data is
not exposed to other tenants. In this case, data for a single tenant is contained
within a separate data partition for the service.
Administration
Administrators can host multiple tenants on the same farm and centrally manage the
deployment of services and features. Tenants can manage the configuration of
administrator-delegated features and control the functionality of their site collections.
Administrative functionality is aligned with common hosting roles, as summarized in the
