AWS::Events::EventBus

• Events are sent to the buses
• Default bus: events generated by AWS services
• Partner event bus: events generated by 3rd party applications (E.g., datadog, zendesk, etc)
• Custom event bus: events generated by your own applications

Schema Registry

• Analyze the events in the bus and infer its schema
• Schema Registry generates code for the application so that it knows how to structure the event before sending
• Schemas can be versioned
