Virtual Private Cloud (VPC) peering enables secure access to cloud data without exposing services to the public internet, allowing for maximum security and privacy. This feature creates a private network "peering" connection between Amazon VPCs and Timescale Cloud VPCs, isolating services and gaining greater control over databases. To configure VPC peering, users must familiarize themselves with networking fundamentals, including IP addresses, subnetting, CIDR, routing, security groups, and VPC settings. For example, users must ensure that there is no overlap between the AWS VPC CIDR block and the Timescale Cloud VPC CIDR block to avoid conflicts. Additionally, users need to configure routes for traffic flow, open port 5432 for incoming connections, and create a security group to allow communication between the two networks. By following these steps, users can establish secure access to their cloud data and maintain maximum security and privacy.
