Thin Client - Thin Clients As Programs

Thin Clients As Programs

The notion of a thin client extends directly to any client–server architecture: in which case, a thin client application is simply one which relies on its server to process most or all of its business logic. This idiom is relatively common for computer security reasons: a client obviously cannot be trusted with the logic that determines how trustworthy they are; an adversary would simply skip the logic and say "I'm as trustworthy as possible!"

However, in web development in particular, client applications are becoming fatter. This is due to the adoption of heavily client-side technologies like Ajax and Flash, which are themselves strongly driven by the highly interactive nature of Web 2.0 applications.

A renewed interest in virtual private servers, with many virtualization programs coming to a ripe stage, means that servers on the web today may handle many different client businesses. This can be thought of as having a thin-client "virtual server" which depends on the actual host in which it runs to do all of its computation for it. The end result, at least, is the same: providing of the computing service for many clients.
