Scalability Server and Virtual Application Deployment

The Virtual Application Package Registration Wizard (which you use to import virtual application images and create packages in the Software Package Library) creates the following software packages for each virtual application image:

• Staging—This package provides access to the virtual application for both standalone and streaming modes of package delivery. This package contains the virtual application image.
• Standalone—This package is used to install and execute the virtual application locally on the target computer.
• Streaming—This package is used to downstream the virtual application from a streaming server and execute it on the local computer.

You deploy the virtual application Staging package to the scalability server. The scalability server also functions as the streaming server for virtual applications. Therefore, Staging packages are deployed to the scalability server for streaming of the virtual application to the target computers.

The Microsoft App-V streaming server uses two protocols for streaming communications: RTSP (not secured) and RTSPS (secured). The default protocol and port for the Microsoft App-V streaming server are RTSP and port 554. If you want to use the secured RTSPS protocol with port 322, you must configure the streaming server. For information about configuring the Microsoft App-V streaming server, see the Microsoft product documentation.

You deploy the Standalone and Streaming packages from the domain manager to the target computers. You can also stage packages on the scalability server before deployment to target computers. You can use standard Software Delivery deployment methods to deploy virtual application packages to target computers.

Note: For more information about virtual application packaging and deployment, see the Software Delivery Administration Guide.
