A private cloud consists of attributes that are built on virtualization but really focus on management infrastructure, hence the use of System Center 2012. A private cloud typically includes pooling of resources; scalability, which is enabled through the pooling of resources; user self-service; chargeback and showback to users; and focus on the application and service.
System Center 2012 can cover the management infrastructure of those requirements:
Use Virtual Machine Manager—which provides insight and abstraction of the virtualization host, storage, and network—to create and manage virtual machines (VMs) through templates
Use Service Manager to support a self-service portal through a central software catalog and to get reports on cloud usage and cost assignment
Use Orchestrator to coordinate the provisioning and modification of VMs and other components
Use Operations Manager to monitor the environment and applications
You could manually implement a private cloud using these four components of System Center 2012. However, Microsoft provides a process pack that simplifies the deployment and configuration of the private cloud, if all four of the above components are already deployed. The System Center Cloud Service Process Management Pack, which is available at the Microsoft download site, includes run books to import into System Center Orchestrator and Management Packs for System Center Service Manager, in addition to detailed installation and operational instructions to fully implement a private cloud using System Center.
