This document discusses the "Framework Principal" pattern which allows optimizing resource usage across multiple applications by initializing shared services and configurations in a single starter class. The Framework Principal runs very early and can be used to launch services independently of any application based on configuration properties. It provides examples of how to configure different applications to use the same Framework Principal by specifying different property files and user names for production vs sandbox environments. This allows launching shared services only once across multiple applications rather than separately in each one.
