Amazon CloudWatch Events enables you to react selectively to events in the cloud as well as in your applications.

You can create CloudWatch Events rules that match event patterns, and take actions in response to those patterns. 

CloudWatch Events lets you process both AWS-provided events and custom events (those that you create and inject yourself). The AWS-provided events that CloudWatch Events supports include:
  • Amazon EC2 instance state-change events.
  • Auto Scaling lifecycle events, and instance launch and terminate notifications.
  • Scheduled events.
  • AWS API call and console sign-in events reported by AWS CloudTrail.
