This pattern demonstrates how to aggregate all your events from multiple event busses (in the same region) to a central event bus in a different region.

This pattern is deployed using Terraform to create a central EventBridge bus, EventBridge rules on fan-in busses and all IAM resources required.

The event busses to aggregate can be defined in terraform.tfvars file (Sample ARNs are provided, replace with event bus ARNs as needed).

The provider.tf file also lists the AWS Regions of the fan-in event bus and central event bus (replace these based on where your event busses exist and where you want your central bus to be created).
