CloudWatch Events
Amazon CloudWatch Events enables you to automate your AWS services and respond automatically to system events such as application availability issues or resource changes. You can write simple rules to indicate which events are of interest to you, and what automated actions to take when an event matches a rule.

When a file is uploaded to a container or removed from a container, two events are fired in succession in the CloudWatch service:

-
Activating an AWS Step Functions state machine
-
Notifying an Amazon SNS topic or an AWS SMS queue
