What is this?
Amazon EventBridge is a serverless event bus routing events from AWS services, SaaS partners, and custom applications to targets.
Why should you care?
AwsVerse decouples order-placed events from inventory, email, and analytics consumers.
See it live — copy this example
Run in AWS CloudShell / local AWS CLI v2, or follow the matching steps in the AWS Console (Free Tier).
aws events put-rule \
--name awsverse-order-created \
--event-pattern '{"source":["awsverse.orders"],"detail-type":["OrderCreated"]}' \
--state ENABLEDWhat happened?
- Rule matches custom events on the default or custom event bus.
- Add targets: Lambda, SQS, Step Functions.
Practice next
- Create custom event bus awsverse-bus.
- Put rule with detail-type pattern.
- Add Lambda target; put-events with test payload.
- Add second target SQS for audit trail.
- Enable event archive for 7 days.
Remember
EventBridge = event router. Schema registry documents events. Archive and replay for debugging.
AwsVerse order fan-out
One checkout triggers five downstream systems.
Outcome: Single OrderCreated event replaces brittle synchronous chain.
