Rich Internet Application- Characteristics To Enhance Your Website

A Rich Internet Application (RIA) is a Web application that has many of the characteristics of desktop applications, typically delivered either by way of a site-specific browser, via a browser plug-in, independent sandboxes, or virtual machines. Adobe Flash, Java, and Microsoft Silver light are currently the three most common platforms, with penetration rates around 99%, 80%, and 54% respectively (as of July 2010). Although new Web standards have emerged, they still use the principles behind IRAs. Users generally need to install a software framework using the computer's operating system before launching the application, which typically downloads updates, verifies and executes the Rich Internet Application. This is the main differentiator from JavaScript-based alternatives like Ajax that use built-in browser functionality to implement comparable interfaces. While some consider such interfaces to be IRAs, some consider them competitors to IRAs and others, including Garner, treat them as similar but separate technologies.

Rich Internet Application dominates in on line gaming as well as applications that require access to video capture (with the notable exception of Mail, which uses its own task-specific browser plug-in). Web standards such as HTML5 have developed and the compliance of Web browsers with those standards has somewhat improved. However, the need for plug-in based IRAs for accessing video capture and distribution has not diminished, even with the emergence of HTML5 and JavaScript-based desktop-like widget sets that provide alternative solutions for mobile Web browsing.

Rich Internet Application present indexing challenges to search engines, but Adobe Flash content is now at least partially index able. 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 Development. For security purposes, most IRAs 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, calculations, reformatting and so forth, thereby lowering the amount and frequency of client-server traffic, especially as compared to the client-server implementations built around so-called thin clients.
