What is microsoft application virtualization l.jpg
What Is Microsoft Application Virtualization?

Microsoft Application Virtualization (App-V) is a virtualization solution that:

  • Enables organizations to respond to the management challenge by providing the capability to make applications available to end-user computers without having to install the applications directly on those computers.

Determine model s needed l.jpg
Determine Model(s) Needed

App-V provides three methods for deploying application virtualization:

  • Option 1: Standalone Model via sequencing and client

  • Option 2: Streaming Model using the native streaming capabilities of App-V

  • Option 3: Full Infrastructure Model provides software distribution, management, and reporting capabilities (includes application streaming)

Option 1 standalone model l.jpg
Option 1: Standalone Model

  • Creates an .msi package as part of application sequencing

    The sequencer creates MSI package, which contains the publication information, shortcuts, and installer routines

  • Use the Standalone Model:

    • With disconnected remote users who cannot connect to App-V infrastructure

    • Where software management systems, such as SCCM 2007 and SMS 2003, are already in place

    • Where network bandwidth limitations prevent electronic software distribution

Option 2 streaming model l.jpg
Option 2: Streaming Model

  • Applications are streamed in feature blocks

    Allows a quick application start; needs only Feature Block 1 (FB1) to load application

  • Uses existing server infrastructure

  • Use the Streaming Model:

    • Where ConfigMgr 2007 SP1 with R2 is already in place and the organization will use it for managing virtual application publishing and delivery

    • Where Active Directory or SQL Server-based servers are not in place, but the organization wants to take advantage of streaming virtual applications

Option 3 full infrastructure model l.jpg
Option 3: Full Infrastructure Model

  • Requires significant additional infrastructure

    • Consists of one or more System Center Application Virtualization Management Servers

    • Requires Microsoft SQL Server database

    • Application Virtualization Management Console required on a management server or a designated management workstation

  • Use Full Infrastructure Model:

    • Where the organization wants to use the Management Server to publish the application shortcuts to the clients

    • Where the additional reporting capabilities of the Management Server are desired

    • When group-based application publishing is required

    • When license enforcement is required

    • For rapid provisioning of applications to clients

Determine number of app v instances l.jpg
Determine Number of App-V Instances

  • Determine number of instances for each model

    • Full Infrastructure Model instance anchored by single SQL Server database. Separate databases define separate instances.

    • Streaming Model instance is defined by Streaming Server that provides virtualized applications to a location. Each location requires a Streaming Server deployed locally.

Assess client considerations l.jpg
Assess Client Considerations

  • App-V Desktop Clients

    • Ensure cache is large enough

  • Terminal Server Clients

    • Ensure clients are pre-cached on Terminal Server for performance reasons

  • App-V Clients

    • Are limited to 32-bit operating systems

    • And must be pre-installed for all models

Sequencer considerations l.jpg
Sequencer Considerations

  • Sequencer should be placed in an isolated environment

    No agents or background applications

  • Virtual machine or physical CPU

    • Must have a second drive with a letter that matches the virtual drive used by the client

    • Default is drive Q

  • Deploying to a staging environment is recommended

Design streaming infrastructure l.jpg
Design Streaming Infrastructure

Three different Streaming Server types:

Determine streaming server scaling and fault tolerance l.jpg
Determine Streaming Server Scaling and Fault Tolerance

  • Streaming Server size is highly dependent on environment in which it’s placed

    • Start with one streaming server (or two if required for fault tolerance)

    • Fault tolerance for Streaming Servers using RTSP/S achieved by load balancing the servers

    • For information about fault-tolerance options available to file servers and IIS, see IPD – Windows Server 2008 File Services and Internet Information Services 7.0

Design full infrastructure model l.jpg
Design Full Infrastructure Model

  • App-V Full Infrastructure Model instance includes these server roles:

    • App-V Management Server

    • Streaming Server

    • Server running App-V Management Web Service

    • SQL Server

    • Active Directory

    • App-V Management Console

    • Sequencer for creating virtualized application packages

    • App-V Client installed on systems requiring app virtualization (desktops, VMs, or Terminal Servers)

Determine full infrastructure server resource scaling l.jpg
Determine Full Infrastructure Server Resource Scaling

  • No definitive numbers available so must determine resource requirements for each App-V role by using performance monitoring tools in Windows Server

  • Decisions to make:

    • Management Server Service — Service can be placed on its own server, or be placed on the Management Server

    • SQL Server — App-V Data Store can be located on a dedicated SQL Server instance, or in a shared database server

    • Management Server Scaling — To scale out, use load balancing

Determine full infrastructure fault tolerance for each role and combining roles l.jpg
Determine Full Infrastructure Fault Tolerance for Each Role and Combining Roles

  • Decisions to make:

    • Management Server Service — Service can be on same server with Management Console unless Management Server is load balanced

    • Microsoft SQL Server — Several SQL Server(s) versions available to provide fault tolerance, as well as possibility of clustering

    • Management Server — Two load balancing options for Management Server: software-based and hardware load balancing

  • Combining Server Roles:

    • Compatible Fault-Tolerant Role Combinations

Summary and conclusion l.jpg
Summary and Conclusion and Combining Roles

  • A combination of models may be required to deliver virtual applications within the organization

  • Carefully consider requirements for streaming infrastructure

  • Planning is key
