6 Microsoft strategy Vision of virtualization IT organization benefit when workloads are decoupled from hardware Increased availability, manageability Long term, workloads will be increasingly dynamic Virtualization is a key enabling technology to achieve this

7 Type of Virtualization Application Virtualisation Microsoft SoftGrid Desktop/Presentation Virtualisation Windows Terminal Services Machine Virtualisation Virtual Server & Virtual PC File Virtualization in Vista ? Hardware Operating System Application Desktop

11 Application Virtualization SoftGrid Traditional Layered Install Model Isolated Virtual Application Model

12 Application Virtualization SoftGrid Applications are virtualized per instance: Files (including System Files) Registry.ini files Fonts COM / DCOM objects Services Semafores, Mutexes Name spaces Applications do not get 'installed' Applications do not alter the host OS Note: Tasks process locally on the host computer

14 Usage Scenarios for Virtualization  Production server consolidation Consolidate low-utilization workloads Legacy OS (NT4) and application re-hosting Resource partitioning (limit resources per VM)  Business continuity management Workload deployment and provisioning OS and application patching (swap VMs) Isolation / sandboxing  Dynamic data center Workload mobility  Development and test Rapid provisioning of multiple virtual machines Undo-disk and save state helpful

15 Usage Scenario Production server consolidation Consolidate workloads Infrastructure applications Branch office and datacenter workloads Low-utilization workloads Efficient use of available hardware resources Re-host legacy OS and applications NT4 guest applications on Win2003 host Run on current hardware and current OS No application updates required Partition resources Limit CPU resource per VM

16 Usage Scenario Business continuity management Workload deployment Quickly switch pre-configured VM (vhd-files) For disaster recovery Eliminate unscheduled downtime OS and application patching Deploy and test patches off-production, and swap Eliminate scheduled downtime Isolation / sandboxing Isolate OS environments for untrusted applications Prevent malicious code from affecting others

17 Usage Scenario Dynamic datacenter Workload mobility Package up entire OS environment and move to other location Flexible deployment of workloads

18 Usage Scenario Development and test Rapid provisioning of virtual machines Provide multiple VMs for testing quickly Use save state to start up quickly Create arbitrary test scenarios Recreate reported issues Avoid use of production network Use undo-disk to rollback to known state Wider test range for niche scenarios Provision multiple VMs with variations Use difference-disks for easy provisioning

19 Usage Scenario Other server consolidation WorkloadMicrosoft productsSample scenario Branch office and department applications Win2003 and Virtual Server 2005 Enterprise customer migrates Windows NT 4.0 applications from 1,000 stand-alone servers to 50 centralized, 4-way, rack-mount systems Enterprise applications Win2003 and WSRM Medium-sized customer moves enterprise resource planning suite onto 8-way systems running Windows Server 2003 and WSRM File and print Windows Storage Server Small business consolidates file and print servers by using network attached storage (NAS) Database Win2003 and SQL Server 2005 Enterprise customer consolidates databases on highly scalable IA-64 systems Win2003 and Exchange Server 2003 Medium-sized business consolidates servers using Exchange Server on scalability cluster Web Win2003 and IIS 6.0 Hosting service consolidates extranet applications on blades

20 Virtualization Support and Licensing Support (two meanings) Supported by Microsoft Product Support Technical possible with the product Needed licenses On host - host OS and Virtual Server ? In guests - guest OS and applications ?

21 Support By Microsoft PSS Vision in WSS Common Engineering Criteria: See - Limitations... all server products will support Microsoft Virtual Server Each product must be capable of running from within a virtual instance. Exemptions will be granted if: The product requires hardware that is not currently supported in the VM environment. Core product scenarios fail because of virtualization performance or scaling issues. Exchange Server Only on Virtual Server 2005 R2 or later (KB ) Certificate Server - Only with Win2003 SP1 or later guest and host (KB ) ISA Server Is supported, but not recommended (KB ) KB Microsoft supports Windows Server System software running within a Microsoft Virtual Server environment subject to the Microsoft Support Lifecycle policy... KB The following Windows Server System software is not supported within a Microsoft Virtual Server environment: Speech Server, ISA Server 2000/2004, MIIS 2003, Sharepoint Portal Server. KB For Microsoft customers who do not have a Premier-level support agreement, Microsoft will require the issue to be reproduced independently from the non-Microsoft hardware virtualization software. KB Microsoft support for Linux guest operating systems is currently limited to the following list of qualified and tested operating systems: [9 Linux distributions]

22 Pricing ProductPrice (US) Virtual PC 2004 After 12-Jul-2006: Free (was $ 129) Virtual Server 2005 Standard Edition $ 499 Virtual Server 2005 Enterprise Edition $ 999 Virtual Server 2005 R2 Standard Edition $ 99 Virtual Server 2005 R2 Enterprise Edition $ 199 Virtual Server 2005 R2 Enterprise Edition * After 1-Jan-2006: Free download Virtual PC 2007 Free download Windows Virtualization Free download * Virtual Server 2005 Standard Edition is no longer available

23 Virtual Server 2005 R2 Free Why would Microsoft do that? Reasons: Customer satisfaction Increase interest in Win2003 R2 EE 1 license = 4 VMs + host Accelerate proof-of-concept test efforts Rapidly deploy workloads (AD / SQL / BizTalk, etc) Ease migration to Longhorn virtualization

24 Licensing Windows server licenses Licensing changes for server products Virtualization friendly (after 1-Dec-2005)  Only count licenses for running VMs  For per-processor licenses, only count virtual CPUs in VM  Single Win2003 R2 EE license: 1 host + 4x Win2003 R2 EE in guest Virtualization unlimited (after 1-Oct-2006)  Single Win2003 R2 Datacenter license: 1 host + unlimited Win2003 R2 (any) guests See -
