AWS EventBridge is a powerful service that simplifies event-driven architectures by allowing multiple AWS services to work together without the need for custom AWS Lambda functions. One of its standout features is EventBridge Pipes, which enables seamless integration between services while reducing the need for custom code.
In this example, James Manson demonstrates how to use EventBridge Pipes to create a “functionless” event-driven architecture. By leveraging EventBridge’s default event bus, you can capture AWS API calls and use its scheduler to automate actions on a one-time or recurring basis.
Example: EventBridge Pipes in Action
Here’s a practical example of how to set up EventBridge Pipes to filter and route events without writing Lambda functions:
1. Create an EventBridge Rule:
aws events put-rule --name "MyEventRule" --event-pattern "{\"source\":[\"aws.s3\"],\"detail-type\":[\"AWS API Call via CloudTrail\"],\"detail\":{\"eventSource\":[\"s3.amazonaws.com\"],\"eventName\":[\"PutObject\"]}}" --state "ENABLED"
2. Set Up a Target for the Rule:
aws events put-targets --rule "MyEventRule" --targets "Id"="1","Arn"="arn:aws:sns:us-east-1:123456789012:MySnsTopic"
3. Create an EventBridge Pipe:
aws pipes create-pipe --name "MyEventPipe" --source "arn:aws:sqs:us-east-1:123456789012:MyQueue" --target "arn:aws:lambda:us-east-1:123456789012:function:MyLambdaFunction" --role-arn "arn:aws:iam::123456789012:role/MyPipeRole"
4. Test the Setup:
Upload a file to your S3 bucket and verify that the event triggers the SNS topic or Lambda function without custom code.
What Undercode Say
AWS EventBridge Pipes revolutionize event-driven architectures by eliminating the need for custom Lambda functions in many scenarios. By leveraging EventBridge’s default event bus and scheduler, you can automate workflows and integrate AWS services seamlessly.
For instance, using EventBridge Rules, you can filter specific S3 events like `PutObject` and route them to an SNS topic or Lambda function. This approach reduces operational overhead and simplifies maintenance.
To further enhance your setup, consider using EventBridge Pipes to connect SQS queues directly to Lambda functions. This eliminates the need for intermediary services and streamlines event processing.
Here are some additional Linux and Windows commands to complement your AWS setup:
- Linux:
- Monitor AWS logs in real-time:
tail -f /var/log/awslogs.log
- Check network connectivity to AWS endpoints:
ping s3.amazonaws.com
Windows:
- Use PowerShell to list S3 buckets:
Get-S3Bucket
- Test EventBridge rule triggers:
Test-EventBridgeRule -RuleName "MyEventRule"
For more advanced use cases, explore the official AWS documentation on EventBridge Pipes: AWS EventBridge Pipes Documentation.
By adopting EventBridge Pipes and Rules, you can build scalable, efficient, and cost-effective event-driven architectures on AWS. Whether you’re filtering S3 events or scheduling recurring tasks, EventBridge provides the tools to simplify your workflows and reduce reliance on custom code.
