    21. 21. Training • Present and reset training image – Just reset the VM – No need to reimage the systems – Network isolation
    22. 22. Training • Microsoft Virtual Labs www.microsoft.com/technet/traincert/virtuallab/default.mspx • Set of preconfigured environments • Microsoft tools and current products – Vista, Exchange 2007, SQL Server 2005, Windows Server 2007, Office 2007
    23. 23. Help Desk • Increase ability to represent multiple product environments • Reduced infrastructure – Physical systems – Space requirements – Power – Cabling • Enhanced test system accessibility • Ability to rollback test system state
    24. 24. Demo: VMware Workstation Creating and restoring VM snapshots
    25. 25. Lab and Deployment Testing • Build a test virtual network infrastructure • Duplicate physical model – Same domain structure and system names – Virtual network clients • Reduced physical system requirements – No need for 1-1 physical systems • Virtual networking – Connects virtual systems – Isolated from production network
    26. 26. Lab and Deployment Testing • Use the virtual network to test – Active Directory, networking, policy changes – Patch testing – Application deployment • Roll out change to production after successful tests in the virtual environment
    27. 27. Disaster Recovery • Fewer servers to manage and recover/restore – Reduces costs • Server VMs are hardware independent – Can be restored to other platforms – No need to match primary site and secondary site hardware • VMs are encapsulated – Faster – Can be replicated between sites – No need for bare-metal installs
    28. 28. Disaster Recovery • Physical-to-VM recovery – Restore physical backup to running VM – Lower costs – no need for 1-to-1 physical servers • VM-to-VM recovery – Protects against operating system/application failure – Recover failed VM on another server
