Consider a data center heavily built on Hyper-V (or VMware) and the ability to clone virtual machines from template VMs or from other existing VMs. For a highly virtualized data center, how does this change the deployment options available from traditional data centers? Is there any benefit or need in using some of the traditional deployment options (e.g., disk imaging using software like Ghost, deploying operating systems using Windows Deployment Services and the Windows Automated Installation Kit or Microsoft Deployment Toolkit)?
