Creating an Amazon EventBridge event bus
You can create a custom event bus to receive events from your applications. Your applications can also send events to the default event bus. When you create an event bus, you can attach a resource-based policy to grant permissions to other accounts. Then other accounts can send events to the event bus in the current account.
The following video goes through creating event buses:
