AWS Resource Access Manager (RAM) now supports global resource types, enabling you to provision a global resource once and share that resource across your accounts. A global resource is a resource that can be used in multiple AWS Regions. For example, you can now create a RAM resource share with an AWS Cloud WAN core network, which is a managed network containing AWS and on-premises networks, and share it across your organization. As a result, you can use the Cloud WAN core network to centrally operate a unified global network across Regions and across accounts.
