Older (Before HTML5) Techniques
Apache Flex, formerly Adobe Flex, is a software development kit (SDK) for the development and deployment of cross-platform RIAs based on the Adobe Flash platform. Initially developed by Macromedia and then acquired by Adobe Systems, Flex was donated by Adobe to the Apache Software Foundation in 2011.
Java applets are used to create interactive visualizations and to present video, three dimensional objects and other media. Java applets are more appropriate for complex visualizations that require significant programming effort in high level language or communications between applet and originating server.
JavaFX is a software platform for creating and delivering RIAs that can run across a wide variety of connected devices. The current release (JavaFX 8, July 2016) enables building applications for desktop, browser and mobile phones and comes with 3D support. TV set-top boxes, gaming consoles, Blu-ray players and other platforms are planned. Java FX runs as plug-in Java applet or via Webstart.
Silverlight was proposed by Microsoft as another proprietary alternative. The technology has not been widely accepted and, for instance, lacks support on many mobile devices. Some examples of application were video streaming for events including the 2008 Summer Olympics in Beijing, the 2010 Winter Olympics in Vancouver, and the 2008 conventions for both major political parties in the United States. Silverlight was also used by Netflix for its instant video streaming service. Silverlight is no longer under active development and is not supported in Microsoft Edge, Microsoft's most recent browser.
The term "rich Internet application" was introduced in a white paper of March 2002 by Macromedia (now merged into Adobe), though the concept had existed for a number of years earlier under names including Remote Scripting, by Microsoft, c. 1999, X Internet, by Forrester Research in October 2000, Rich (Web) clients, and Rich Web application.
Security issues in older standards
Security can improve over that of application software (for example through use of sandboxes and automatic updates), but the extensions themselves remain subject to vulnerabilities and access is often much greater than that of native Web applications. For security purposes, most RIAs run their client portions within a special isolated area of the client desktop called a sandbox. The sandbox limits visibility and access to the file-system and to the operating system on the client to the application server on the other side of the connection. This approach allows the client system to handle local activities, reformatting and so forth, thereby lowering the amount and frequency of client-server traffic, especially versus client-server implementations built around so-called thin clients.
In November 2011, there were a number of announcements that demonstrated a decline in demand for rich internet application architectures based on plug-ins in order to favor HTML5 alternatives. Adobe announced that Flash would no longer be produced for mobile or TV (refocusing its efforts on Adobe AIR). Pundits questioned its continued relevance even on the desktop and described it as "the beginning of the end". Research In Motion (RIM) announced that it would continue to develop Flash for the PlayBook, a decision questioned by some commentators. Rumors state that Microsoft is to abandon Silverlight after version 5 is released. The combination of these announcements had some proclaiming it "the end of the line for browser plug-ins".
