Final answer:
A nonbuffered event-based implicit invocation architecture includes message topic, event sources, and event listeners.
Step-by-step explanation:
The partition of a nonbuffered event-based implicit invocation architecture includes the following:
- Message topic: This identifies the type or category of the event.
- Event sources: These are the entities that generate events.
- Event listeners: These are the entities that receive and process events.
A message queue is not part of the partition of a nonbuffered event-based implicit invocation architecture.
