Starting today, inter-region Amazon Virtual Private Cloud (Amazon VPC) peering can now be setup between the Amazon Web Services China (Beijing) Region, operated by Sinnet and the Amazon Web Services China (Ningxia) Region, operated by NWCD.
Inter-region Amazon VPC peering allows VPC resources, such as Amazon EC2 instances, Amazon RDS databases, and Amazon Lambda functions, to communicate with each other while running in different Amazon Web Services Regions. Since inter-region VPC peering uses private IP addresses, it does not require gateways, VPN connections, or a separate physical hardware. It provides a simple and cost-effective way to share resources between regions and replicate data for geographic redundancy. Built on the same horizontally-scaled, redundant, and highly-available technology that powers Amazon VPCs, inter-region VPC peering traffic has no single point of failure or bandwidth bottleneck. Traffic using inter-region VPC peering never traverses the public internet, thereby reducing threat vectors, such as common exploits and DDoS attacks.
Data transferred across inter-region VPC peering connections is charged at the standard inter-region data transfer rates.
