Cloud Integration Hub
Publications and Subscriptions

Publications and subscriptions are entities that define how applications publish data to
Cloud Integration Hub
and how applications consume data from
Cloud Integration Hub
. Publications publish data to a defined topic and subscriptions subscribe to topics.
Publications and subscriptions control the data flow and the schedule of data publication or data consumption. An application can be a publisher and a subscriber. Multiple applications can publish to the same topic. Multiple applications can consume data from the same topic.
Publications and subscriptions can publish from and subscribe to any type of source and target that
Informatica Intelligent Cloud Services
supports. You can publish from and subscribe to different sources of data. Because the publishing process and the consuming process are completely decoupled, the publishing source and the consuming target do not have to be of the same data type. For example, you can publish data from a file and consume it into a database.
Publications and subscriptions can publish and consume data by triggering a Data Integration task or with an API. For publications and subscriptions that trigger a Data Integration task, you create the tasks in
Informatica Intelligent Cloud Services
. You then select a task when you create the publication or subscription in
Cloud Integration Hub
. For publications and subscriptions that are triggered by an API, you run the API manually.
