VPC peering is a networking solution that allows two Virtual Private Clouds (VPCs) to connect and communicate using private IP addresses, enhancing security and performance without relying on the public internet. This method facilitates direct traffic flow between VPCs, consolidating resources and securing communication between organizations. However, it comes with limitations such as non-transitivity and manual configuration and management requirements. Implementing VPC peering involves several key steps, including preparation, initiating and accepting the peering connection, and updating route tables, security groups, and testing the connection. Best practices for effective VPC peering include comprehensive network planning, clear naming conventions, regular audits, and automating setup where possible. Common issues arise from overlapping IP ranges and misconfigured route tables, but can be addressed through planning, audits, and alternative solutions. VPC peering is a foundational component of modern cloud networking, requiring careful consideration of its benefits and limitations to achieve success.
