EventBridge Configuration

This module configures EventBridge (formerly CloudWatch Events) for event-driven architecture.

Overview

EventBridge provides:

• Event routing
• Scheduled events
• Custom event buses
• Event filtering

Configuration

The EventBridge setup includes:

• Custom event bus
• Scheduled rule (every 5 minutes)
• Custom event rule
• Lambda function targets

Usage

Send Custom Event

aws events put-events \
  --entries '[{
    "Source": "devops-studio.dev",
    "DetailType": "Custom Event",
    "Detail": "{\"message\": \"Hello from EventBridge\"}"
  }]'

Scheduled Events

Events are automatically triggered every 5 minutes. The Lambda function will process them.

Monitoring

View EventBridge metrics in CloudWatch:

aws cloudwatch get-metric-statistics \
  --namespace AWS/Events \
  --metric-name Invocations \
  --dimensions Name=RuleName,Value=devops-studio-dev-scheduled-rule \
  --start-time $(date -u -d '1 hour ago' +%Y-%m-%dT%H:%M:%S) \
  --end-time $(date -u +%Y-%m-%dT%H:%M:%S) \
  --period 300 \
  --statistics Sum

Best Practices

1. Use Custom Buses - Separate buses for different applications
2. Filter Events - Use event patterns to filter
3. Monitor - Track event delivery and failures
4. Retry Logic - Configure retries for failed events
