Reference: Amazon EventBridge event patterns and types for Systems Manager

Note Amazon EventBridge is the preferred way to manage your events. CloudWatch Events and EventBridge are the same underlying service and API, but EventBridge provides more features. Changes you make in either CloudWatch or EventBridge are reflected in each console. For more information, see the Amazon EventBridge User Guide.

Using Amazon EventBridge, you can create rules that match incoming events and route them to targets for processing.

An event indicates a change in an environment in your own applications, software as a service (SaaS) applications, or an AWS service. Events are produced on a best effort basis. After an event type that is specified in a rule is detected, EventBridge routes it to a specified target for processing. Targets can include Amazon Elastic Compute Cloud (Amazon EC2) instances, AWS Lambda functions, Amazon Kinesis streams, Amazon Elastic Container Service (Amazon ECS) tasks, AWS Step Functions state machines, Amazon Simple Notification Service (Amazon SNS) topics, Amazon Simple Queue Service (Amazon SQS) queues, built-in targets and many more.

For information about creating EventBridge rules, see the following topics:

• Monitoring Systems Manager events with Amazon EventBridge

• Amazon EventBridge event examples for Systems Manager

• Getting started with Amazon EventBridge in the Amazon EventBridge User Guide
