EventBridge

About

• Creation: Based on events happening in different AWS sources EventBridge receives events from different sources such as,

  • Scheduled CronJobs

  • Event Pattern

    • Based on event rules to react to a service doing something.

• Filtering: Events can be filtered at event bridge.

• Event: JSON document about event details.

• Destinations: Different destinations can be configured such as Trigger Lambda Functions, send SNS/SQS messages to different Destinations.

Partner EventBus

• Allows to integrate with different AWS SAAS Partner products like DataDog, Zendesk etc

Custom EventBus

• Applications can send events to custom event bus, which can process events based on its logic.

• Refer this to see how we can create one.

---

• Event Bus can be accessed by other AWS accounts using Resource based policies.

• Events (all/filtered) can be archived and sent to an event bus for a period of time/indefinitely, also these archived events can be replayed.

Schema Registry

• Event Bus can analyse the events in your bus and infer the schema.

• The Schema Registry allows you to generate code for application, that will know in advance how data is structured in the event bus.

• Schema can be versioned.

• Resource based policies allow to manage permission for a specific Event Bus.

• Allow/Deny events from another AWS account or AWS region.

• Aggregate all events from your AWS Organtization in a single AWS account or AWS region.
