Functions provide the capability to execute custom business rules at any level (cloud and edge) with the same architecture.

Functions are divided into two main parts, called Workers and Triggers.

A Worker is the Function itself. It allows you to create its custom-base function and enables you to subscribe to an “Event Trigger”.

A Trigger is a component that is capable of invoking serverless Functions from an event source. Triggers work as a listener to a particular endpoint. It enables the capturing of events and messages from different sources and redirects them to one or more Functions. Triggers convert incoming events to HTTP requests to asynchronously invoke all the Functions that match certain criteria.

Both Triggers and Functions must be configured according to the events that fire the Functions.
