SMN is a reliable, extensible, and massive event notification service. SMN significantly simplifies system coupling. It can automatically push messages to subscribers through emails, text messages, and applications. For example, after users upload or delete objects, SMN notifies users of the operations.
You can set event notification by the prefix and suffix of an object. For example, add an event and specify that the notification is sent only when the files suffixed with .jpg or prefixed with images/ are added to the storage bucket.
