Answer: 
Explanation:
The VMM can provide a self Service Portal for VM provisioning itself so no need for Service Manager
or else.
Author: Grants members permission to author templates and profiles. Users with authoring rights
can create hardware profiles, operating system profiles, application profiles, SQL Server profiles,
virtual machine templates and service templates.
Deploy: Grants members permission to deploy virtual machines and services from templates and
virtual hard disks that are assigned to their user role. However, they do not have the right to author
templates and profiles.
(Expanded in VMM to include creation of Services)
Start: Grants members permission to start their own virtual machines and Services.
