Introducing CloudWatch Events - Monitor and rapidly react to changes in your Amazon Web Services resources

Amazon CloudWatch now provides a stream of events describing changes to your AWS resources, such as an Amazon Elastic Compute Cloud (EC2) instance coming into service or failing a system health check, the Auto Scaling service adding instances to a deployment, or suspicious API call patterns being logged in AWS CloudTrail.
