Get Events in motion with Event Mesh & Async APIS

8. “Event-driven APIs are a new style
of API that uses a subscription
“push” model rather than the
request-response model of
conventional RESTful APIs.
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.”

Services”, 24 Sept 2020, Twiggy Lo, Brendan Williams
