How to use AWS VPC Peering?

AWS VPC Peering allows two different VPCs to connect through Private IP without allowing RDS/EC2 to be accessed by the public network. Make sure your needs meet the VPC peering limitations before starting.

First, you must ensure that Canner Enterprise and your source VPC exist. Assume that your VPC information is as follows:

(Please make sure to replace the VPC information with your VPC information; the following information is only for demonstration)

Notice: CIDRs of two VPCs cannot be the same.

  • Canner Enterprise VPC
ID: vpc-db3e09bc
CIDR: 172.31.0.0/16
Account: 365545700901
  • DataSource VPC
ID: vpc-08279f19bf4d9f74a
CIDR: 10.3.0.0/16
Account: 956019317291

We must enable Canner Enterprise VPC to connect to DataSoruce VPC through the EC2 instance.
