16### Event Bus
17 
18Channel that receives events. Types:
19- **Default**: Receives AWS service events
20- **Custom**: Your application events
21- **Partner**: SaaS application events
22 
23### Rules
24 
25Match incoming events and route to targets. Each rule can have up to 5 targets.
26 
27### Event Patterns
28 
29JSON patterns that define which events match a rule.
30 
31### Targets
32 
33AWS services that receive matched events (Lambda, SQS, SNS, Step Functions, etc.).
34 
35### Scheduler
36

48 
49# Create rule
50aws events put-rule \
51  --name order-created-rule \
52  --event-bus-name my-app-events \
53  --event-pattern '{
54    "source": ["my-app.orders"],
55    "detail-type": ["Order Created"]
56  }'
57 
58# Add Lambda target
59aws events put-targets \
60  --rule order-created-rule \
61  --event-bus-name my-app-events \
62  --targets '[{
63    "Id": "process-order",
