Transcript

  • 1. Virtualization Strategies: Virtual Technology Real Results Bryan Von Axelson IT Pro Evangelist Microsoft
  • 2. What this session covers IT Challenges Virtualization Market Trends Scenarios for Server Virtualization Scenarios for Application Virtualization Planning for Hardware Virtualization
  • 3. IT Challenges
  • 4. 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
  • 5. 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
  • 6. Virtualization Trends
  • 7. 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
  • 8. Virtualization Market Growth 5 fold growth in virtualization market place More expensive servers Virtualization management IDC Server Virtualization September 2005
  • 9. Server Virtualization Scenarios Server consolidation Multiple OS & application support Lab and deployment testing Training Help desk Disaster recovery Application isolation Intrusion detection Security
  • 10. Server Sprawl New application = new server
  • 11. Problems Server Sprawl Hardware – Increased hardware acquisition costs – Increased infrastructure requirements – Increased hardware maintenance costs – Increased hardware replacement costs
  • 12. Problems of Server Sprawl Administration – Patch management – Backup and recovery – Server management and troubleshooting
  • 13. Servers Deployed Less than 10 1% 10 - 25 8% 26 - 99 13% 100 - 249 26% 250 - 499 13% 500 - 999 9% 1,000 - 4,999 6% 5,000 or more 6% Don't know 18% 0% 10% 20% 30% IDG Server Consolidation Research July 2006
  • 14. Multiple Vendor Support 1 vendor 6% 2 17% 3 29% 4 14% 5 13% 6 4% 7 2% 8 1% 9 1% 10 - 25 2% Over 25 vendors 2% Don't know 9% 0% 10% 20% 30% IDG Server Consolidation Research July 2006
  • 15. Biggest Challenges Patch management 63% Resource utilization 60% Maintenance costs 44% Server sprawl 42% Interoperability 27% Downtime 25% Other 6% Don't know 2% 0% 10% 20% 30% 40% 50% 60% 70% IDG Server Consolidation Research July 2006
  • 16. Server Consolidation Strategy No Yes 28% 70% Don’t know 2% IDG Server Consolidation Research July 2006
  • 17. Server Consolidation Increase hardware utilization Reduced costs – Fewer systems – Less power – Less cooling – Lower IT resources Reduced Infrastructure – Fewer racks – Fewer switches
  • 18. 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
  • 19. OS Support 40% 32% 30% 24% 21% 20% 14% 10% 6% 3% 0% 5 or more 4 3 2 1 Don't know IDG Server Consolidation Research July 2006

  • 21. Training Present and reset training image – Just reset the VM – No need to reimage the systems – Network isolation
  • 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. 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. 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
  • 25. 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
  • 26. Demo: Virtual Server Using Undo Disks
  • 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. 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
  • 29. High Availability for Hosts Primary Site Recovery Site
  • 30. Clustering Guest to Guest Host to Host SAN or iSCSI iSCSI connection connection Cluster Cluster storage storage
  • 31. Application Isolation Sandboxing Use browser in VM Isolated from host Discard changes when finished
  • 32. 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/
  • 33. 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
  • 34. Security Forensic Analysis Duplicate a compromised system – P2V makes an exact working copy – Offsite analysis Snapshots – Point-in-time copies
  • 35. Application Virtualization Scenarios
  • 36. Running Incompatible Applications Different versions of Microsoft Office Running beta software Running multiple Java virtual machines
  • 37. 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
  • 38. Application Reliability SoftGrid – Application Reset • Overwrites malfunctioning applications – User controlled – Application restreamed Altris – Layer Reset – User controlled – Restores original layer
  • 39. Demo: Application Virtualization
  • 40. Hardware Virtualization Technology
  • 41. 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
  • 42. Windows Server 2007 Hypervisor Hardware assisted virtualization – Intel Virtualization Technology (VT) – AMD Virtualization Technology (AMD-V) Windows Server 2007 Hypervisor – 180 days after RTM Compatible with MS VM Images Compatible with XEN-enabled Linux
  • 43. 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
