This document discusses virtualization strategies and trends. It outlines key IT challenges like simplifying management, reducing costs, and increasing security. Benefits of virtualization include reduced administration efforts, lower costs, improved resource utilization and increased availability. Server virtualization can enable server consolidation, support of multiple OS/applications, lab/deployment testing and disaster recovery. Application virtualization allows running incompatible applications in isolation. Planning for hardware virtualization involves ensuring appropriate licensing and addressing performance considerations.

What this session covers • IT Challenges • Virtualization Market Trends • Scenarios for Server Virtualization • Scenarios for Application Virtualization • Planning for Hardware Virtualization
IT Challenges
IT Challenges • Simplify Management – Information and organizational growth – Patching and software updates – Increase availability – System deployment – Regulatory compliance • Reduce Costs – Server sprawl – System and application maintenance – Infrastructure costs • Increase Security – AV & Spam – Threat protection
Virtualization Benefits • Reduces administrative efforts – Lowers operational costs • Fewer servers to manage – Speeds deployment • Now 1-6 weeks (requisition, setup, software, test) • Virtual reduces this to hours • Reduced hardware and infrastructure costs • Improves resource utilization • Increases availability • Tools to enhance security
Virtualization Trends
Virtual Server Growth • Tremendous growth in virtual servers • 1M servers by 2009 • WinHec – Bob Muglia – Virtualization will be the norm – All workloads will be virtualized in 2-4 years IDC Server Virtualization September 2005
Virtualization Market Growth • 5 fold growth in virtualization market place • More expensive servers • Virtualization management IDC Server Virtualization September 2005
Server Virtualization Scenarios • Server consolidation • Multiple OS & application support • Lab and deployment testing • Training • Help desk • Disaster recovery • Application isolation • Intrusion detection • Security
Server Sprawl • New application = new server File/Print File/Print File/Print Database Database Application Application Application Application Application Application Application Application
Problems Server Sprawl • Hardware – Increased hardware acquisition costs – Increased infrastructure requirements – Increased hardware maintenance costs – Increased hardware replacement costs
Problems of Server Sprawl • Administration – Patch management – Backup and recovery – Server management and troubleshooting

Server Consolidation Strategy Don’t know 2% No 28%Yes 70% IDG Server Consolidation Research July 2006
Server Consolidation • Increase hardware utilization • Reduced costs – Fewer systems – Less power – Less cooling – Lower IT resources • Reduced Infrastructure – Fewer racks – Fewer switches
Multiple O/S & Applications • Linux Interoperability – Shared hardware • Legacy OS Support – Windows NT 4.0 – Limited support for modern hardware • ISV Applications – Restricted platform support

Training • Present and reset training image – Just reset the VM – No need to reimage the systems – Network isolation
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
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
Demo: VMware Workstation Creating and restoring VM snapshots
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
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
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
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
High Availability for Hosts Primary Site Recovery Site
High Availability for VMs
MS VS2005 Cluster Primary Site Recovery Site
Application Isolation • Sandboxing • Use browser in VM • Isolated from host • Discard changes when finished
Application Isolation • VMware Browser Appliance – VMPlayer – Runs any VM (VMware or Microsoft) www.vmware.com/download/player/ – Browser Appliance • Ubuntu 5.1 & Firefox www.vmware.com/vmtn/appliances/directory/browserapp.html – Other Virtual Appliances • 300 Prebuilt Virtual Appliances www.vmware.com/vmtn/appliances/directory/
Intrusion Detection • Honeypotting – Create a “production look alike” – Logging sensors to record attack activity – Microsoft Honeymonkey http://research.microsoft.com/HoneyMonkey/ – VM Honeypots are recongnizable
Security • Forensic Analysis • Duplicate a compromised system – P2V makes an exact working copy – Offsite analysis • Snapshots – Point-in-time copies
Application Virtualization Scenarios
Running Incompatible Applications • Different versions of Microsoft Office • Running beta software • Running multiple Java virtual machines
Demo: Altiris SVS Creating an Application Layer and running multiple versions of Office
No Touch Application Deployment • SoftGrid – SoftGrid client is deployed – Application is sequenced • Stored on application server – User is added to AD SoftGrid group – Application is streamed from server to client • Partial app streaming results in fast code delivery – Altiris • AppStream
Application Reliability • SoftGrid – Application Reset • Overwrites malfunctioning applications – User controlled – Application restreamed • Altris – Layer Reset – User controlled – Restores original layer
Hardware Virtualization Technology
Hardware Virtualization • Why? – Performance – No direct virtualization for older x86 & x64 – Virtual Machine Additions • Change the guest OS allowing the VM kernel mode to run on the processor – Hardware Virtualization • Enables VM code to run on processor in virtualized mode • No significant difference for VM Additions • Big difference for unsupported operating systems
Windows Server 2008 Hypervisor • Hardware assisted virtualization – Intel Virtualization Technology (VT) – AMD Virtualization Technology (AMD-V) • Windows Server 2008 Hypervisor – 180 days after RTM • Compatible with MS VM Images • Compatible with XEN-enabled Linux
Virtualization Gottcha’s • You still need licenses – OS & any CALs – Windows Server 2003 Datacenter R2 is the exception • Performance – Shared hardware resources – VMM overhead • Can result in more server sprawl
Server Consolidation Resources • Mixed Workload Consolidation Guide • www.microsoft.com/downloads/details.aspx?FamilyId=0F70695E- 5D0B-4781-8966-84BE43216F9E&displaylang=en • Consolidating SQL Server • www.microsoft.com/technet/prodtechnol/sql/2000/deploy/32bitconso lidation.mspx • Consolidating Domain Controllers • www.microsoft.com/technet/itsolutions/ucs/ds/dmcnmgsa.mspx • Consolidating File and Print Servers • http://www.microsoft.com/technet/itsolutions/ucs/fp/cmfp/cmfpwnt4. mspx • Consolidating Web-based applications • www.microsoft.com/windowsserversystem/overview/benefits/consoli dation/bestpractices.mspx
