What is AWS CloudWatch Events?
AWS CloudWatch Events is a service that allows you to monitor your AWS resources and respond to events that occur in real-time.

When an event occurs, CloudWatch Events can trigger automated workflows, such as sending a notification or invoking a Lambda function.
How does AWS CloudWatch Events work?
To use AWS CloudWatch Events, you first define the events you want to monitor using rules. A rule matches incoming events based on a set of conditions, such as the event source or the event type. Once a rule matches an event, you can configure one or more targets to respond to the event. Targets can be AWS services, such as SNS, Lambda, or Step Functions, or custom HTTP endpoints.
