1. Can you peer VPCs in different regions? No, VPC peering is limited to VPCs within the same region. To connect VPCs across regions, you would need to use VPN or AWS Direct Connect.

But AWS document says that we can peer the vpc across regions: When you establish peering relationships between VPCs across different AWS Regions, resources in the VPCs (for example, EC2 instances and Lambda functions) in different AWS Regions can communicate with each other using private IP addresses, without using a gateway, VPN connection, or network appliance. The traffic remains in the private IP space. https://docs.aws.amazon.com/vpc/latest/peering/what-is-vpc-peering.html
