7.5 Amazon Event Bridge on AWS S3

What is Amazon EventBridge?

Amazon EventBridge is a serverless event bus service that makes it easy to connect applications using data from your own apps, integrated Software-as-a-Service (SaaS) applications, and AWS services. EventBridge simplifies the architecture of your applications by enabling them to react to data changes in your S3 buckets, DynamoDB tables, and more, without the need for polling or other inefficient methods.

Key Features of Amazon EventBridge:

1. Serverless Event Bus: Easily route events between AWS services, your own applications, and SaaS applications without managing infrastructure.
2. Easy Integration: Connect with various AWS services and SaaS applications seamlessly.
3. Real-Time Data Streaming: Respond to changes in your environment in real-time.
4. Scalable: Automatically scales with your application’s needs.
5. Secure: Ensures data is securely managed and transferred.

Integrating Amazon EventBridge with AWS S3

Integration via AWS Management Console

1. Login and Navigate: Log in to your AWS Management Console and navigate to the Amazon EventBridge service.
2. Create a Rule: Click on ‘Create Rule’ and specify the event source. For integrating with S3, select the bucket you want to monitor.
3. Define Event Pattern: Specify the type of events you want to monitor (e.g., object creation, deletion).
4. Set Target: Choose the AWS service or resource that should respond to the event. It could be a Lambda function, an SNS topic, or another service.
5. Review and Create: Review your settings and create the rule. Your S3 bucket is now integrated with EventBridge.

Integration via AWS CLI

1. Install AWS CLI: Ensure that the AWS CLI is installed and configured on your machine.
2. Create Event Rule: Use the create-rule command to create a new EventBridge rule. Specify the event source and details.

aws events put-rule --name "DailyLambdaFunction" --schedule-expression "cron(0 9 * * ? *)"

3. Set Up Permissions: You may need to set up permissions for EventBridge to access your S3 bucket. Use the put-permission command if necessary.

aws lambda add-permission ...

4. Specify Target: Use the put-targets command to specify what action should be taken when the rule is triggered.

aws events put-targets --rule MyS3EventRule --targets ...

1. Test and Validate: Test the integration by performing actions in your S3 bucket that match the event pattern. Monitor the response to ensure it works as expected.

Why Integrate EventBridge with S3?

• Automated Workflows: Automate workflows in response to S3 events, like processing data as soon as it’s uploaded.
• Real-Time Monitoring: React to changes in your S3 buckets in real-time.
• Reduce Complexity: Simplify your application architecture by eliminating the need for polling mechanisms.

Conclusion

Integrating Amazon EventBridge with AWS S3 streamlines your cloud-based applications, making them more efficient and responsive. Whether through the Management Console or the CLI, setting up this integration is straightforward and brings a multitude of benefits, from real-time data processing to simplified application architectures.
