A tenant is an isolated instance of NSX Advanced Load Balancer. Each NSX Advanced Load Balancer user account is associated with one or more tenants.
The tenant associated with a user account defines the resources that the user can access within NSX Advanced Load Balancer. When a user logs in, NSX Advanced Load Balancer restricts their access to only those resources that are in the same tenant. If a user is associated with multiple tenants, each tenant still isolates the resources that belong to that tenant from the resources in other tenants. To access resources in another tenant, the user must switch the focus of the management session to that other tenant.
