What Is Server Virtualization?

Server virtualization enables multiple virtual machines to run on one physical host

Benefits:• Server consolidation• Service or application isolation• Simplified server deployment• Increased service and application

availability• Multiple operating systems can run on one

consistent platform


What Is Desktop Virtualization?

Desktop virtualization provides options for virtualizing client operating systems Desktop virtualization provides options for virtualizing client operating systems

Desktop virtualization option

Description

Client-Hosted Virtual machines run on the user desktop to provide an alternate computing environment

Virtual Desktop Infrastructure

Client virtual machines are hosted in the data center and accessed through remote desktop

Microsoft Enterprise Desktop Virtualization

Provides the tools to build and deploy client virtual machines to user desktops


What Is Presentation Virtualization?

• Presentation virtualization runs applications on centralized servers • Windows Server 2008 R2 Remote Desktop Services replaces Terminal Services • Presentation virtualization runs applications on centralized servers • Windows Server 2008 R2 Remote Desktop Services replaces Terminal Services

Benefits include:

• Centralized data • Simplified application management • Integration with application virtualization Potentially improved performance


What Is Application Virtualization?

Application virtualization provides virtual environments for applications running on user desktopsApplication virtualization provides virtual environments for applications running on user desktops

Benefits include:

• Enables potentially incompatible applications to run on one computer

• Application deployment is easier • Virtual application use is transparent to users Virtual applications are easy to deploy


What Is Cloud Computing?Cloud computing enables access to IT services through the InternetCloud computing enables access to IT services through the Internet

A cloud computing infrastructure includes:

• Data center with virtualization hosts • Virtual servers, storage and network resources• Highly available and high bandwidth network• Automated tools for managing virtual machines• Tools for managing online and local integration

Benefits include:

• Flexible deployment options • Scalability • Decreased cost• Improved service availability


When identifying server workloads to virtualize, consider:

• Hardware requirements• Compatibility• Supportability• Licensing• Availability requirements

Evaluation Factors


Overview of Virtualization Solution Accelerators

Microsoft Virtualization Solution Accelerators provide guidance and tools that help you design and implement virtualizationMicrosoft Virtualization Solution Accelerators provide guidance and tools that help you design and implement virtualization

• Microsoft Assessment and Planning Toolkit • Infrastructure Planning and Design Guides • Offline Virtual Machine Servicing tool• Security Compliance Management Toolkit Series• Microsoft Deployment Toolkit

Assessment Features of the MAP Toolkit

The MAP toolkit provides:

• Hardware inventory • Agentless collection of data• Collects information about the hardware, drivers, and applications

installed on target computers• Data Analysis

• Identifies candidates for upgrading to new operating systems or for virtualization

• Readiness Reporting • Detailed reports on findings


Demonstration: Assessing the Computing Environment by Using the MAP Toolkit


Designing a Solution for Server Virtualization

1. Determine the virtualization scope 2. Create a list of potential workloads that you want to virtualize 3. Determine backup and fault-tolerance requirements for each workload 4. Design and place hardware for a virtualization host 5. Map workloads to hosts 6. Design host backup and fault tolerance 7. Determine storage requirements 8. Determine network requirements

Virtual Machine OverviewVirtual machine components include:

• Virtual processors• Memory• Network Adapters• Virtual Disks

Virtual machines can run:

• Windows Server 2008 and Windows Server 2008 R2• Windows Server 2003 SP2 and Windows Server 2003

R2 SP2• Windows 2000 Server, SP4• Redhat and Suse Linux• Windows 7, Windows Vista and Windows XP SP2 or later


Understanding Hypervisors

Hypervisors come in several different flavors . They can be categorized, for example,

• by type—that is, by whether they run directly on the physical hardware or within (hosted by) an operating system environment .

• by design—that is, whether they are monolithic or microkernel .


Type 1 Hypervisorrun directly on bare metal

• Microsoft Hyper-V• Citrix XenServer• VMware ESX Server


Type 2 hypervisors run within an operating system environment

• Microsoft Virtual Server• VMware Server


Monolithic vs. Microkernel

Planning for Disks and Storage

Hyper-V host computers can use:

• Directly attached storage• Storage Area Networks

Virtual machines require storage for:

• Virtual hard disk files• Snapshots• Failover clustering• Application data files


Determining Availability Requirements for Virtual Machines

To provide high availability, you can use:

• Virtual machine network load balancing for Web-based applications • Application clustering for applications that are failover clustering aware • Host-based failover clustering to make virtual machines highly available


Securing the Hyper-V Server Role

• Apply standard security policies to both host computers and virtual machines• Use a Server Core installation of Windows Server 2008 R2 for host computers• Use the security level of your virtual machines to determine the security level

of your management operating system • Do not give virtual machine administrators permissions on the management

operating system • Configure the network settings to enhance security • Use BitLocker Drive Encryption to protect resources

Consider the following:

Design Considerations for External, Internal, and Private Virtual Networks

• Use private networks to enable virtual machines to communicate with on virtual machines on the same host

• Use internal networks to enable virtual machines to communicate with other virtual machines on the same host and with the host computer

• Use external networks to enable virtual machines to communicate with other computers on the corporate network


What Are the Storage Options for Virtual Machines?

IDE SCSI

• Two IDE controllers• Two devices each

• Emulated/synthetic

• Four SCSI controllers• 256 devices each

• Methods supported:• Pass-through• Fixed-disk• Dynamic

• Synthetic
