Determine message and event scenarios

Does sending component expect the communication to be processed in a specific way?

Action	Description	When to use
Event	- Light weight. - Includes a publisher and a subscriber.	Used for boradcasts and are often ephemeral. Ephemeral means the communication might not be handled by any receiver if none is currently subscribing.
Message	- Contains raw data, produced by one component, that will be consumed by another component. - Contains the data itself, not just a reference to that data.	Used where the distributed application requires a guarantee that the communication will be processed.
