Design, distribution, cost

Rich Internet applications use a Rich Applicant deployment archetypal (deployment of a aggregate applicant appliance through a browser) rather than a thin-client-server archetypal (where the user's appearance is abundantly controlled from the server).

Flash, Silverlight and Java are appliance platforms accessed by the user's web browser as plug-ins. These appliance platforms absolute the bulk of abstracts downloaded during initialization to alone what is all-important to affectation the page. The browser constituent is alone downloaded once, and does not charge to be re-downloaded every time the folio is displayed; this reduces appliance amount time, bandwidth requirements, and server load.

Proponents of RIAs advance that the amount of RIA development and O&M is about lower than that of HTML-based alternatives due to added developer abundance and standardized, backwards accordant attributes of the appliance belvedere runtime environments. A 2010 abstraction conducted by International Abstracts Corporation approved an boilerplate accumulation of about $450,000 per appliance in the case of Flash belvedere development (in affiliation with use of the accessible antecedent Flex SDK), a 39% abridgement in amount over a three-year period.14
