Inter-Region VPC Peering is Now Available in Nine Additional AWS Regions

Posted on: Feb 20, 2018

Starting today, Inter-Region Virtual Private Cloud (VPC) Peering is available in US West (Northern California), EU (London), EU (Paris), Asia Pacific (Mumbai), Asia Pacific (Sydney), Asia Pacific (Singapore), Asia Pacific (Tokyo), Canada (Central) and South America (São Paulo) Regions in addition to AWS US East (Northern Virginia), US East (Ohio), AWS EU (Ireland), US West (Oregon) Regions.

Inter-Region VPC Peering allows VPC resources like Amazon EC2 instances, Amazon RDS databases and AWS Lambda functions running in different AWS Regions to communicate with each other using private IP addresses, without requiring gateways, VPN connections or separate physical hardware. It provides a simple and cost-effective way to share resources between regions or replicate data for geographic redundancy. Built on the same horizontally scaled, redundant, and highly available technology that powers VPC today, Inter-Region VPC Peering encrypts inter-region traffic with no single point of failure or bandwidth bottleneck. Traffic using Inter-Region VPC Peering always stays on the global AWS backbone and 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.
