Appboard/2.4/software components

Overview

AppBoard consists of a number of software components working together to deliver the overall features. In actual deployments the architecture may also include some custom (external to AppBoard) components in addition to the core AppBoard product, and any external product integrations.

This page details the individual software components. For a more general overview of how AppBoard works, refer to the Overview page.

Main Components

Configuration Database

In a default install the configuration database is purely in-memory and running within the Tomcat process. In other words, there is no external process or ports.

In clustering or high-availability environments AppBoard can be configured to use an external configuration database. This is via a JDBC driver and requires network connectivity to the external database.

AppBoard Clients

AppBoard clients are supported Web Browsers running the Builder or Viewer in an Adobe Flash Player plug-in.

All rendering takes place within the client and this is comprised of native flash content (via the flash plugin) and HTML frames (via the browser).

The client communicates with the AppBoard server using HTTP/HTTPS over a single port for all resources, data communications, and enPortal proxied content. Non-proxied content, and some widgets such as the Google Map or Tile Map, the client may need additional network connectivity beyond the AppBoard server.

Additional Credits

AppBoard incorporates the use of some 3rd party libraries. See the License Credits page for more information.
