Microsoft Application Virtualization Technical Overview
Realize greater efficiency and responsiveness for software deployments and updates.
Application virtualization is at the heart of Microsoft Application Virtualization (App-V). It decouples applications from the operating system and enables them to run as network services. Application virtualization can be layered on top of other virtualization technologies—network, storage, machine—to create a fully virtual IT environment where computing resources can be dynamically allocated in real-time based on real-time needs. App-V's patented application virtualization, dynamic streaming delivery, and centralized management technologies make everything from deployments and upgrades to migrations and business continuity initiatives easier and faster with better agility:
Application virtualization: Enable applications to run without the need to visit a desktop, laptop, or terminal server. Applications are no longer installed on the client—and there is minimal impact on the host operating system or other applications. The most extensive virtualization technology on the market, App-V virtualizes per user, per application instance, as well as key application components. As a result, application conflicts and the need for regression testing are dramatically reduced.
Dynamic streaming delivery: Applications are rapidly delivered, when needed, to laptops, desktops, and terminal servers. In most cases only a small percentage of the application is needed to launch the application. Additional components are delivered when transparently requested by the application. This results in faster delivery of the application when needed.
Centralized, policy-based management: Virtual Application deployments, patches, updates, and terminations are more easily managed via policies, and administered through the App-V console or via your ESD system. Use Microsoft App-V Application Virtualization to help reduce the complexities inherent in enterprise application management. With App-V you can reduce challenges and transform your computing environment into a dynamic, services-oriented infrastructure.
The diagram illustrates the key components of Microsoft App-V Application Virtualization.
Virtualized application environments enable each application to bring its own set of configurations and run without any installation within a virtual run-time abstraction layer on the client, so dependencies or effects on the configuration of the operating system are minimized. However, since applications execute locally, they run with full performance, functionality, and access to local services—including cut and paste, OLE, printing, network drives, and attached devices.
The table below illustrates how application virtualization interacts with the operating system and other virtualized applications.
Standard Operating System Environment: In standard OS environments, applications install their settings onto the host operating system, hard-coding the entire system to fit that application's needs. Other applications' settings can be overwritten, possibly causing them to malfunction or break.
The Virtual Application Environment: With application virtualization, each application brings down its own set of configurations on-demand, and executes in a way so that only it sees its own settings.
Side-by-Side Virtualization: Each App-V enabled application brings down its own set of configurations and can run side by side without the settings conflicting with each other—or the host operating system. Despite this separation, inter-application communication with other App-V applications and those installed locally is preserved, allowing for cut and paste, OLE, and all other standard operations.
