Amazon EventBridge Rule Icon

Amazon EventBridge rules automate responses to events in your AWS accounts or software applications. You define rules that 'listen' for specific events – such as a new file uploaded to S3, a database change, or a custom application event. When an event matching a rule's criteria occurs, EventBridge triggers a pre-configured action, like sending a notification, running a Lambda function, or updating a database. This lets you easily build event-driven architectures without writing complex event handling code, simplifying your applications and improving their responsiveness.
