Example Concept: Inter-region VPC peering is a networking model that connects VPCs in different regions within the same cloud provider, enabling private IP communication without traversing the public internet. This setup typically involves configuring peering connections in each VPC, updating route tables to direct traffic through the peering connection, and ensuring that security groups and network ACLs allow the necessary traffic. It is crucial to consider the cost implications of data transfer across regions and to ensure compliance with any data residency requirements.
