Can a VPC Peering Connection Connect VPCs in Different Regions?

A VPC peering connection only can connect VPCs in the same region.

Figure 1 shows an application scenario of VPC peering connections.
  • There are two VPCs (VPC-A and VPC-B) in region A that are not connected.
  • Service servers (ECS-A01 and ECS-A02) are in VPC-A, and database servers (RDS-B01 and RDS-B02) are in VPC-B. The service servers and database servers cannot communicate with each other.
  • You need to create a VPC peering connection (peering-AB) between VPC-A and VPC-B so the service servers and database servers can communicate with each other.
