To enable access to customers’ Amazon VPCs, AWS Direct Connect is announcing Direct Connect gateway, a new feature to allow customers using any AWS Direct Connect location in China to use their Direct Connect connections to access any Virtual Private Cloud (VPC) deployed in any AWS Regions in China. In addition, each Direct Connect gateway will enable association with one or more Amazon VPCs. Using Direct Connect gateway, you do not need to have AWS Direct Connect connections in multiple AWS Regions to access your Amazon VPCs in those AWS Regions. Rather, you can use one (or more) private virtual interface to communicate with multiple Amazon VPCs across any AWS China Regions.
