What Is Infrastructure Planning & Design? Guidance that aims to clarify and streamline the planning and design process for Microsoft ® infrastructure technologies IPD…in 50 pages: Defines decision flow Describes decisions to be made Relates decisions and options for the business Frames additional questions for business understanding Replaces Windows Server System™ Reference Architecture (WSSRA) Page 3 |

SELECTING THE RIGHT VIRTUALIZATION TECHNOLOGY Getting Started Page 4 |

Why Use Virtualization? Scenarios driving virtualization: Server consolidation – lower datacenter costs Application migration Increased IT agility – reduced deployment and provisioning time Software development and training Page 5 |

Purpose and Overview Purpose To assist in the decision process regarding which technology to use to meet business and technical requirements Agenda Determine a virtualization technology Locate the IPD guide to use to plan and design the infrastructure for the technology Page 6 |

Page 9 | Decision Flow Walk through the scenario for each application Arrive at a decision Repeat for each scenario

Areas to consider when determining if virtualization is appropriate include: Compatibility Supportability Licensing Business benefits Page 10 | Step 1. Determine Whether Virtualization Is Appropriate

Step 2. Categorize the Application: Server or Client Page 11 | Is the application designed to run on: A server operating system? Proceed to “Select Server Hardware Virtualization or Software Virtualization” A client operating system? Proceed to “Determine Client Connectivity” Click this button to proceed Click this button to proceed Back to previous decision

Step 3. Select Server Hardware Virtualization or Software Virtualization Use the table below to select between: Windows Server 2008 Hyper-V Virtual Server 2005 R2 SP1 Page 12 | CriteriaWindows Server 2008 Hyper-V Virtual Server 2005 R2 SP1 32-bit host 64-bit host Multiple CPU support for guest OS Enhanced management tools Type 1 hypervisor (server hardware virtualization) Server software virtualization Return to the start to process the next application Back to previous decision

Step 4. Determine Client Connectivity Option 1: Connected Client Client computers that will have reliable network connections Client computers that will not need to run the application when disconnected from the network Proceed to: “Determine Application Location” Option 2: Disconnected Client Client computers that will run the application while disconnected from the network Proceed to: “Choose Application or Desktop Virtualization” Page 13 | Click this button to proceed Click this button to proceed Back to previous decision

Step 5. Determine Application Location Option 1: Centralized Application The application can be run and managed on a server Tight control is required, and application resources are in a central location Easier to deploy and manage If the application will be run centralized, proceed to “Select Desktop or Presentation Virtualization” Option 2: Decentralized Application The application cannot run on a server Individualized configurations are required by different users Access to local resources is required If the application will be run decentralized, proceed to “Choose Application or Desktop Virtualization” Page 14 | Click this button, to proceed Click this button, to proceed Back to previous decision

Step 6. Select Desktop or Presentation Virtualization Option 1: Desktop Virtualization The entire desktop must be virtualized, both the operating system and the applications The operating system is Windows Vista Use Vista Enterprise Centralized Desktops (VECD) Option 2: Presentation Virtualization One or more applications must be virtualized The applications can support multiple users Use Windows Server 2008 Terminal Services Page 15 | Return to the start, to process the next application Back to previous decision

Step 7. Choose Application or Desktop Virtualization Option 1: Application Virtualization One or more applications must be virtualized The client’s operating system supports the application Use Microsoft Application Virtualization 4.5 Option 2: Desktop Virtualization The entire desktop must be virtualized, both the operating system and the applications The client operating system is Windows XP or Windows Vista Use Virtual PC Page 16 | Return to the start, to process the next application Back to decision : Determine Application Location Back to decision : Determine Client Connectivity

Additional Considerations Managing the Virtualization Environment Microsoft provides two products to assist with the challenges of managing a virtualized environment: Microsoft System Center Virtual Machine Manager Microsoft Enterprise Desktop Virtualization Microsoft virtualization management products can be used to manage the organization’s virtualized environment—for example, to quickly provision new virtual machines Page 17 |
