Amazon CloudWatch Events (CWE) is a stream of system events describing changes in your AWS resources.

Q

What is the difference between CloudWatch Events and AWS CloudTrail?

Events

Amazon CloudWatch | Management Tools

A

CloudWatch Events is a near real time stream of system events that describe changes to your AWS resources. With CloudWatch Events, you can define rules to monitor for specific events and perform actions in an automated manner. AWS CloudTrail is a service that records API calls for your AWS account and delivers log files containing API calls to your Amazon S3 bucket or a CloudWatch Logs log group. With AWS CloudTrail, you can look up API activity history related to creation, deletion and modification of AWS resources and troubleshoot operational or security issues.
