AWS EventBridge is a powerful service for building event-driven architectures without writing custom Lambda functions for every integration. With EventBridge Pipes, you can connect AWS services seamlessly, reducing complexity and operational overhead.
You Should Know:
1. EventBridge Pipes Setup
EventBridge Pipes allows you to create direct integrations between services like SQS, DynamoDB, Kinesis, and SNS without writing Lambda code.
Example Command:
aws pipes create-pipe \ --name "SQS-to-SNS-Pipe" \ --source-arn "arn:aws:sqs:us-east-1:123456789012:MyQueue" \ --target-arn "arn:aws:sns:us-east-1:123456789012:MyTopic" \ --role-arn "arn:aws:iam::123456789012:role/EventBridge-Pipes-Role"
#### **2. Event Filtering with Rules**
EventBridge Rules allow fine-grained event filtering, ensuring only relevant events trigger downstream services.
**Example Rule Pattern:**
{
"source": ["aws.s3"],
"detail-type": ["AWS API Call via CloudTrail"],
"detail": {
"eventSource": ["s3.amazonaws.com"],
"eventName": ["PutObject", "DeleteObject"]
}
}
#### **3. Schedule-Based Automation**
EventBridge Scheduler enables cron-based or one-time AWS API triggers.
**Example Command:**
aws events put-rule \ --name "Daily-Backup-Trigger" \ --schedule-expression "cron(0 2 * * ? *)" \ --state "ENABLED"
#### **4. Cross-Account Event Routing**
Forward events across AWS accounts using EventBridge.
**Example Command:**
aws events put-permission \ --event-bus-name "default" \ --action "events:PutEvents" \ --principal "123456789012" \ --statement-id "CrossAccountAccess"
### **What Undercode Say:**
AWS EventBridge Pipes and Rules simplify serverless architectures by eliminating unnecessary Lambda functions. Key takeaways:
– Use EventBridge Pipes for direct service integrations.
– Apply fine-grained filtering to reduce unnecessary event processing.
– Leverage scheduled rules for time-based automation.
– Enable cross-account event sharing for distributed workflows.

### **Expected Output:**
A streamlined, event-driven AWS architecture with minimal custom code, improved scalability, and reduced operational costs.
