10. Issues with Event Driven Architecture
Developers lack visibility into existing events, their current use, and details on how to reuse
an existing event.
IT teams lack industry-standard best practices and conventions for defining machine and
human-readable event driven APIs.
Developers need to work with multiple protocols(JMS, MQ, Kafka, SNS etc) which can be
challenging.

Async API

12. Async API support in Anypoint Platform
12
Design: In Design Center , we can create Async API specification or import one from Anypoint
Exchange.
Publish: In Anypoint Exchange, we can add non-managed instances to our Async API asset.
Note: Anypoint Studio and Flow Designer do not support Async API. If we try to import Async API
in Anypoint studio, an error message will be displayed.

13. Components of Async API
13
Events: Message or data to be shared with other services.
Channels: Destination of the message to be sent or received.
Transport: Technology that transports the message, such as Rabbit MQ, Kafka, Anypoint MQ etc.
