This creates an even playing field for all developers, at least when it comes to development costs: Developers still need to deploy their apps in a way that can handle potentially millions of users per day. Developers are also free to engineer their applications as they wish, choosing almost any technology they desire to write their app. With the proxy server model, Facebook can open its platform to developers through REST web services, and can provide APIs with high integrability to the Facebook look and feel, without needing to provide hosting services for each and every third-party application.

The Facebook Application Modelįacebook uses a proxy server model to allow web developers to integrate to its platform.
