App-V Streaming Server Overview

Formerly Lightweight Server (LWS):

Streaming is the term used to describe the process of obtaining content from a sequenced application package, starting with Feature Block 1, and then obtaining additional blocks as needed, which allows the application to be quickly available for the user.

The virtual application package content is placed on App-V Streaming Servers so that the package can be streamed to the clients on demand and be cached locally. File servers and Web servers can also be used as streaming servers. The streaming server should be on the same high-speed LAN as the clients.

The App-V Streaming Model consists of one or more Streaming Servers and the App-V Clients; another mechanism such as an electronic software distribution system or Group Policy will need to be used to publish the application icons to the client. This server has streaming capabilities, including active/package upgrade without the Active Directory or SQL Server requirements; however, it does not have a Desktop Configuration Service, licensing or metering capabilities. This service relies on the manual or scripted addition of a manifest file for virtual application configuration.

App-V Lightweight Infrastructure components can seamlessly integrate with existing ESD solutions by leveraging App-V streaming and the App-V client capabilities.

This App-V Steaming server infrastructure provides two additional options:

•

The RTSP Streaming Server is typically used to deploy a branch model, enabling you to scale too many locations and maintain the out-of-the-box Active Upgrade capabilities. This is useful when the customer does not want to deploy SQL servers at each location but still requires streaming capabilities. An App-V Management Server is deployed centrally, and streaming servers are deployed in each branch. This is recommended for customers who do not have an existing ESD solution and will leverage App-V management infrastructure. Use in branch office scenarios where the server will reside on the local area network and the data will not traverse the WAN or Internet.

•

The HTTP Streaming Server allows you to use an existing ESD infrastructure and add a new http server to stream applications. HTTP streaming is optimized for Internet/intranet delivery over wide area networks and is recommended for Internet-facing scenarios and businesses that require streaming capabilities across large, disperse networks. Active Upgrade is not available when using HTTP streaming.

In a load-balanced environment, which is typical of large deployments, all servers in a server group should stream the same applications. If App-V Streaming Servers are to stream different applications, assign the servers to different server groups. In this case, you also might need to increase a server group's capacity.
