​Overview

System Center 2012 cloud and datacenter management solutions empower you
with a common management toolset for your private and public cloud applications
and services. System Center helps you confidently deliver IT as a Service for
your business. Virtual Machine Manager 2012 Release Candidate (RC) is key to
delivering the promise of the System Center 2012 release. Virtual Machine
Manager 2012 enables you to:

Deliver flexible and cost effective Infrastructure
as a Service (IaaS). You can pool and dynamically
allocate virtualized datacenter resources (compute, network, and storage)
enabling self-service infrastructure experience for your business, with flexible
role based delegation and access control.

Apply cloud principles to provisioning and servicing your
datacenter applications with techniques like service modeling, service
configuration and image based management. You can also state-separate your
applications and services from the underlying infrastructure using server
application virtualization. This results in a “service centric” approach to
management where you manage the application or service lifecycle and not just
datacenter infrastructure or virtual machines.

Optimize your existing investments by managing
multi-hypervisor environments, including Hyper-V, Xen and VMware.

Dynamic optimization of your datacenter resources based on
workload demands, while ensuring reliable service delivery with features like
high availability.

Best-of-breed virtualization-management for Microsoft
workloads like Exchange and Sharepoint.
