The purpose of Google Cloud VPC peering is to allow private connections between Virtual Private Clouds (VPCs). This means that when two VPCs are peered, they can communicate with each other as if they are part of the same network, while still remaining logically separate. This secure connection does not traverse the public internet, which enhances security and performance for workloads that require private access to resources across different VPCs.

With VPC peering, applications running in different VPCs can exchange data seamlessly without needing to expose that traffic to the public internet, reducing latency and increasing the privacy of the transfer. VPC peering is particularly useful in scenarios where organizations want to connect different departmental networks or when multiple projects need to share resources securely.

By establishing such private connections, VPC peering facilitates collaboration and resource sharing in a secure manner that is essential for the performance and security of cloud-based applications.
