# Network Manager Attachment

An AWS Network Manager Attachment represents a connection between a core network and an external resource, such as a VPC, VPN, or transit gateway. It defines how different network components are linked within the AWS Global Network, enabling centralized management of connectivity, routing, and policies across multiple regions and accounts.
