Dynamic Application Virtualization
Turn physical applications into virtual applications that are never installed but can seamlessly communicate with the local operating system, middleware, plug-ins, and other applications.
From a user perspective virtual applications must appear and function like any physically installed application. As in preparing a physical application for enterprise deployment, virtual applications require preparation before being publishing. The preparation process is easy and the tools are powerful. Microsoft Application Virtualization (App-V) has all the capabilities you need to create virtual application packages for your business needs.
The Microsoft Application Virtualization Sequencer is a wizard-based tool that packages and virtualizes Windows applications for real-time delivery via your App-V infrastructure or a third-party software distribution system. In App-V 4.5 we have added new functionality to the Sequencer including Dynamic Suite Composition and the ability to create an MSI to install the virtual application. The Sequencer has sequenced thousands of applications using the following steps:
1.
Creates the virtual application run-time environment known as the “virtual bubble”: The Sequencer monitors and records interactions between the application and operating system during application installation and execution. It analyzes which OS components the application uses or depends upon, including specific DLL versions. From this information, the Sequencer creates a virtual application package.
2.
Prepares an application package for on-demand streaming: The Sequencer converts hierarchical file system data into App-V's optimized multimedia file format. Enterprise IT departments that support hundreds of applications for thousands of users can use scripting to help expedite the sequencing of new applications, as well as dynamically updating existing applications, accelerating their delivery and use.
3.
Transforms existing application package libraries into virtual applications without having to re-configure their existing packages: Existing repackaged applications in MSI files can be run inside the Sequencer, enabling these packages to be virtualized without new coding or reconfiguration. By automatically detecting file-type associations, the Sequencer simplifies the usability of the application by end users. Existing IT packaging groups can continue to focus on their core packaging expertise in MSI, Installshield, and other packaging methods without having to shift their entire focus to Sequencing. Additionally, App-V Sequence can now create MSI Installer-based virtual applications.
4.
Logging and information display for each application, including update history, helps manage the sequencing process.
Dynamic Suite Composition (DSC), a new feature in App-V 4.5, provides the flexibility to control virtual application interaction. Administrators wanting to consolidate virtual environments, and enable faster, easier administration, can use the product’s Dynamic Suite Composition, which sequences and manages packages for middleware applications separately from the main application. It shrinks potential package size by eliminating redundant packaging of middleware, allowing, for instance, multiple Web applications to communicate with the same instance of a virtualized Java Runtime Environment (JRE). This “many-to-one” capability greatly reduces the cost and effort of updating the common virtual middleware component. It also makes it easier to deploy and manage applications with multiple plug-ins and add-ins, and improves management of plug-in distribution to different user groups.
Using Dynamic Suite Composition, virtual applications can now communicate with each other; share resources such as middleware, plug-ins, and data; or be combined into the same virtual environment.
Independent virtual environments where applications can run side by side but do not communicate or share resources.
