Amazon EventBridge¶

EventBridge is the next evolution of CloudWatch Events
Default Event Bus - generated by AWS services (CloudWatch Events)
Partner Event Bus - receive events from Saas service or applications (Zendesk, DataDog, Segment, Auth0...)
Custom Event Buses - for your own applications
Event buses can be accessed byh other AWS accounts
You can archive events (all/filter) sent to an event bus (indefinitely or set period)
Ability to replay archived events
Rules: how to process the events (like CloudWatch Events)

Schema Registry¶

EventBridge can analyze the events in your bus and infer the schema
The Schema Registry allows you to generate code for your application, that will know in advance how data is structured in the event bus
Schema can be versioned.

Manage permissions for a specific Event Bus
Example: allow/deny events from another AWS account or AWS region
Use case: aggregate all events from your AWS Organization in a single AWS account or AWS region

Amazon EventBridge builds upon and extends CloudWatch Events
It uses the same service API and endpoint, and the same underlying service infrastructure
EventBridge allows extension to add event buses for your custom applications and your third-party SaaS apps.
Event Bridge has the Schema Registry capability
EventBridge has a different name to mark the new capabilities
Over time, the CloudWatch Events name will be replaced with EventBridge
