You can deliver the events to other accounts through a new CloudWatch Events resource called Event Bus. Event buses accept events from AWS services, other AWS accounts, and PutEvents API calls. All AWS accounts have one default event bus. To send events to another account, you simply write rules to match the events of interest and attach an event bus in the receiving account as the target to the rule. The PutTargets API has been updated to allow adding cross account event buses as targets. In addition, we have released two new APIs: PutPermission which allows you to add permissions to your default event bus, and RemovePermission which allows you to remove existing permissions.
