Our modern systems and applications are constantly generating events. These events could be generated by service requests, application events, health checks, etc.
Event source plugins within Event-Driven Ansible act as a bridge between Ansible and event generating applications and services.
Event source plugins allow rulebooks to receive events from things like cloud services, applications and brokers.
Within a rulebook, event sources are called by name and parameters included in the rulebook source configuration are passed into the event source plugin.
