Oracle Notification Service (ONS)

The Oracle Cloud Infrastructure Notifications service broadcasts messages to distributed components through a publish-subscribe pattern, delivering secure, highly reliable, low latency and durable messages for applications hosted on Oracle Cloud Infrastructure and externally. Use Notifications to get notified when event rules are triggered or alarms are breached, or to directly publish a message.

Use the Notifications API to broadcast messages to distributed components by topic, using a publish-subscribe pattern. For information about managing topics, subscriptions, and messages, see Notifications Overview.
