  • 1. Virtualization Landscape Jose Nunez, CISSP, CEH, TOGAF-EA 8
  • 2. Agenda Introduction: Virtualization Technologies Virtualization Use-Cases Conclusions
  • 3. The players
  • 4. Why Virtualize Servers?
    • IT flexibility/agility
      • Predictable scaling to dynamically respond to business needs
      • Key part of disaster recovery strategy
    • Server or data center consolidation
      • Higher utilization leads to greater consolidation
      • Promotes greater centralization and security
    • "Green Computing"
      • Consume less power, cooling, and real estate
    • Support DevTest environments
      • Works for both IT shops and development houses
    • Desktop virtualization
  • 5. Platform Architecture
    • Hypervisor runs on bare metal
      • Extremely thin; only 50K lines of code
      • Processor and memory access through hypervisor
    • Network and storage
      • Accessed through management domain
      • Uses standard Linux device drivers
    Xen Control Interface Virtualized Hardware Hardware VT/AMD-V Drivers Storage Open Source Control Interface
  • 6. Emulation Virtualization User Apps User Apps Hardware HALT SAFE HALT Legacy Hypervisor Slow, expensive software emulation layer
  • 7. Next-Generation Virtualization
    • Paravirtualization
    • Kernel and I/O paths know they are being virtualized
    • Cooperation provides best performance
    User Apps User Apps Hardware HALT HYPERCALL HALT Xen VT/AMD-V Paravirtualized guests makes high-speed calls directly to the hypervisor Other guests benefit from hardware-accelerated call translation
    • Hardware-assisted
    • Hardware-assist allows high performance without emulation
  • 8. Agenda Virtualization Use Cases Introduction: Virtualization Technologies Conclusions
  • 9. Server Consolidation Server sprawl due to silos is reduced New applications introduced without mandating additional hardware Virtual Servers SAP SAP SAP SAP CRM CRM BI BI
  • 10. Fast, Effortless Provisioning
    • Traditional "virtual" provisioning
      • Create virtual machine
      • Duplicate virtual disk/virtual machine to create new virtual machines
    • Improves provisioning with templates
      • Creating a virtual machine from a template is single-step
      • New virtual machines provisioned in seconds
    Provision A
  • 11. Simplify DevTest
    • Two aspects to DevTest
      • IT infrastructure
      • Application development
    • Improve IT DevTest flexibility
      • Smaller organizations do not have full DevTest environments
      • Replicate production environment with fraction of the resources
      • Qualify patches and application changes
      • Push images rapidly from DevTest (virtual) to production (physical)
    • Enhance application development on XenApp
      • Create virtual servers for application development silos
      • Especially complementary for off-shore development
  • 12. Support Zero-Downtime Hardware Maintenance Shared Storage Repository
  • 13. Add DR to Virtualized Server Farms Export Guest VMs Import Guest VMs Servers @ Site 1 Servers@ Site 2 Guests can be exported from one environment and imported into a DR environment
  • 14. Desktop virtualization Server Virtualization Desktop Virtualization ($MILLIONS) $2,000 $1,000
  • 15. Globalization Cost of desktop maintenance and support Regulatory compliance and data security User flexibility and business continuity
  • 16. Virtual Desktop Infrastructure A step in the right direction Virtual Delivery Protocol Desktop Appliance VM VM Infrastructure VM VM VM
  • 17. Task Workers Standardized Server-Based Desktops Knowledge Workers Personalized Windows Desktops 250 users 25 users 30% 60%
  • 18. Patch High Risk & High Cost Desktops & Apps on every server Storage Desktop image sprawl
  • 19. Separate Desktops and Apps Best App Compatibility, Low TCO and Best Performance Single desktop image 90% less storage
  • 20. High Speed Virtual Delivery (ICA) Virtualization Infrastructure Provision virtual desktops from a single image Complete VDI System Desktop Appliance
  • 21. Consider desktop virtualization when:
    • Doing desktop rollouts
    • Desktop security for compliance and IP protection
    • Business continuity
    • Desktop refresh
  • 22.
    • “ We’re excited to expand our work around desktop and server virtualization technologies”
  • 23.
    • Desktop Appliance
    A new class of devices built for Virtual Desktops
  • 24. Agenda Conclusions Virtualization Use Cases Introduction: Virtualization Technologies
  • 25. Key Takeaways
    • Highly complementary: server virtualization and desktop virtualization
      • Add resiliency and flexibility IT operations
      • Easily support rapid provisioning, high availability, DR, and DevTest
      • Obviously, your (virtualization) mileage may vary
    • Virtualization is not just for the datacenter anymore
      • 40% lower cost of desktop maintenance & support
      • Reduced risk of data loss
      • Deliver desktops quickly a reliably to any location
    • Don´t forget app virtualization
