Events
Events are all around us…

6. • APIs define how computer systems
interact
• APIs have defined semantics or
behavior to model information
exchange effectively
• APIs are usually not visible, and
offer no UI
• An event is a change of the
application state that has already
happened
• Event is immutable and can’t be
undone
• Events don’t have a known
destination

Architects must develop new approaches to mediating
and governing event-driven APIs, because API
management platforms designed only for RESTful APIs
may not be sufficient
