Distributed Event Bus system allows to publish and subscribe to events that can be transferred across application/service boundaries. You can use the distributed event bus to asynchronously send and receive messages between microservices or applications.

On the other hand, Background jobs are used to queue some tasks to be executed in the background.

You can read the Background Jobs and Distributed Event Bus docs to learn more.
