OpenWhisk is an event-driven compute platform. OpenWhisk allows application developers to write and host application logic agnostic of the infrastructure on which it will run. This application logic is then triggered through events that can come from Bluemix services or other applications or sources. Such application logic are also called as actions. The uniqueness of this compute platform is that it is triggered only when an event occurs, which means that the trigger caused by an event will result in the application on OpenWhisk to be deployed and executed; if no event occurs the application unit does not run and hence does not use any infrastructure resources:
