You can now configure EventBridge to send and receive events between event buses in the same AWS account and Region, to aggregate all your events from different event buses into a single event bus. You can also fan out events from a single event bus to other event buses, making it easier to decouple applications and produce more extensible, maintainable event-driven architectures within your organization.

EventBridge is a serverless event bus that enables you to create scalable event-driven applications by routing events between your applications, third-party SaaS applications, and other AWS services. You can set up routing rules to determine where to send your data, allowing application architectures to react to changes in your data and systems as they occur. Amazon EventBridge makes it easy to build event-driven applications because it takes care of event ingestion, delivery, security, authorization, and error handling.

To send events to another event bus, you only need to specify the Amazon Resource Name (ARN) of that event bus as the target for any new or existing rule, using the AWS Management Console or using the AWS SDK. Events sent to another event bus are billed as per custom events pricing. To learn about pricing, please visit the EventBridge pricing page.  

You can send and receive events between event buses within the same AWS account in the following Regions: US East (N. Virginia), US West (Oregon and N. California), Middle East (Bahrain), EU (Ireland, Stockholm, Paris), and Asia Pacific (Tokyo, Singapore, Sydney), with more Regions to follow.
