How ColdFusion Fits into Flash Applications

I like to think of remote services (services provided by a computer other than the computer the client is running on) as extensions of the client. In fact, once you get used to incorporating a server-side aspect to your Flash applications—and especially once you have a library of reusable services in place—it is difficult to think of application development without integrating server-side functionality.

Writing services in ColdFusion provides some nice options to Flash application developers. ColdFusion is simple enough to allow the Flash developer to also write the remote services that his application needs. Alternatively, projects can be organized to create more of a division between remote services and the client code that uses them. One team of developers can provide various remote services, such as database interaction or email capability, while another team builds the front end of the application that makes use of those services.
