What are S3 Event Notifications?

Think of S3 Event Notifications as "alarms" that go off whenever something happens to your files in an S3 bucket. Whether a file is uploaded, deleted, or copied, S3 can instantly notify other systems so they can take action.

Introducing Amazon EventBridge

If S3 notifications are the alarms, Amazon EventBridge is the "postman." It is a serverless event bus that connects different parts of your AWS applications. It takes events from S3 and delivers them to targets like:

• AWS Lambda: To run custom code.
• Amazon SNS: To send emails or SMS alerts.
• AWS Step Functions: To start complex workflows.

How the Flow Works

1. The Action: A file is uploaded or deleted in your S3 bucket.
2. The Notification: S3 creates an event describing that action.
3. The Bridge: The event is sent to Amazon EventBridge.
4. The Target: EventBridge triggers another service (like sending an email) based on rules you've set.

How to Enable Integration

Enabling this connection is simple and done directly in the AWS Console:

• Go to your S3 Bucket.
• Click on the Properties tab.
• Find the Amazon EventBridge section.
• Click Edit, turn it On, and save your changes.
