Create EventBridge rules

When an event is emitted by Amazon EC2 Auto Scaling, an event notification is sent to Amazon EventBridge as a JSON file. You can write an EventBridge rule to automate what actions to take when an event pattern matches the rule. If EventBridge detects an event pattern that matches a pattern defined in a rule, EventBridge invokes the target (or targets) specified in the rule.

You can use the example procedures in this section as a starting point.
