VPC Peering

Available in VPC

You can use VPC peering to communicate with other VPCs in an internal network through private IPs, without going through internet communication. It allows you to enjoy the exclusive network expansion effect as well as secure communication.

• VPC peering is available only within the same region.
• Communication is available only in one direction, so if a two-way communication such as TCP is required, 2 VPC peerings must be created by switching the VPC on the requesting end and the VPC on the accepting end.
• VPC peering is not connected in a transitive relationship, and you can't communicate with other VPCs or external network through a VPC that has been peered.
