- 16. @eljuanchosf Why? • Open Source->https://github.com/openwhisk/openwhisk • Easy to understand • Integration with many of Bluemix’s services • Swift and Javascript support • Run Docker containers! • Download it and run it yourself. :)
- 17. @eljuanchosf Concepts Triggers A named channelfor a class of events. Fired by using a list of k,v pairs. -> EVENT! Can be explicitly fired by a user or by an external event source. Rules: Associates one trigger with one action Actions: Stateless code snippets that run inside OpenWhisk Can be invoked or respond to an event Actions can call more actions, setting chains of actions
- 18. @eljuanchosf Concepts/2 Feeds A external eventsource that fires a trigger Packages A bundle of actions and feeds Can be used together with other actions and packages Can be explicitly fired by a user or by an external event source. Polling: $ wsk activation poll
