Each System Center 2012 R2 product plays a different role within a private cloud environ-
ment. Understanding which product you would leverage to complete each task is an impor-
tant part of the 70-247 exam. The following pages provide a brief description of the basic
purpose of each System Center 2012 R2 product in a private cloud deployment.
Virtual Machine Manager
Virtual Machine Manager (VMM) allows you to manage your organization's virtualization
infrastructure, including virtualization hosts, storage, and networking resources. You can use
VMM to create, manage, deploy, and update VMs. You can also use VMM to create, man-
age, deploy, and update applications and services that are hosted within your organization's
private cloud. VMM supports management of virtualization hosts running Hyper-V, VMware
ESX and ESXi, as well as Citrix Xen.
You can use VMM to perform the following tasks:
■
Automatically place new VMs on virtualization hosts that have the most available
resources. This feature is termed intelligent placement.
■
Automatically move virtual machines between cluster nodes based on cluster node
workload and available resources. This includes evacuating VMs off of host cluster
nodes so that VMM can shut those nodes down to preserve electricity.
■
Deploy and manage Server App-V applications.
■
Manage the process of VM live migration between virtualization hosts.
■
Manage software updates for VMM infrastructure, including VMM servers and virtual-
ization hosts.

App Controller
App Controller includes a Self-Service Portal. You can grant access to this Self-Service Portal
to allow users to deploy services and applications to your organization's private cloud, as well
as to the Microsoft Azure public cloud. You grant access by delegating the appropriate roles
and permissions. App Controller allows an application's owner to scale out, or scale back in,
an application. Scaling out allows the application to have access to increased resources as
demand for those resources escalates. In System Center 2012 R2, App Controller functions as
VMM's Self-Service Portal. Previous versions of VMM had their own Self-Service Portal.
