Application Services

Application Services are the means to extract, process/transform and send event/reading data from EdgeX to an endpoint or process of your choice.

Application Services are based on the idea of a "Functions Pipeline". A functions pipeline is a collection of functions that process messages (in this case EdgeX event/reading messages) in the order that you've specified. The first function in a pipeline is a trigger. A trigger begins the functions pipeline execution. A trigger is something like a message landing in a watched message queue.

Any application built on top of the Application Functions SDK is considered an App Service. This SDK is provided to help build Application Services by assembling triggers, pre-existing functions and custom functions of your making into a pipeline.

Note Application Services has replaced Export Services in this EdgeX release.
