AWS EventBridge

ELI5 — The Vibe Check

EventBridge is like a post office for your cloud events. Services drop off messages ('user signed up,' 'order placed'), and EventBridge routes them to the right recipients based on rules you set. It's pub/sub on steroids — it even connects to SaaS apps like Shopify and Zendesk. Your microservices finally have a reliable gossip network.

Real Talk

Amazon EventBridge is a serverless event bus that connects applications using events from AWS services, custom applications, and SaaS partners. It uses rules with pattern matching to route events to targets like Lambda, Step Functions, SQS, and more. It supports schema discovery, event replay, and archive.

Show Me The Code

# EventBridge rule (AWS CLI)
aws events put-rule \
  --name "OrderPlaced" \
  --event-pattern '{
    "source": ["com.myapp.orders"],
    "detail-type": ["OrderPlaced"]
  }'

# Add Lambda as target
aws events put-targets \
  --rule OrderPlaced \
  --targets "Id"="1","Arn"="arn:aws:lambda:...:processOrder"
