inter-VPC peering policy

Inter-VPC peering policy defines the rules and configurations that govern communication between separate Virtual Private Clouds (VPCs) within or across cloud regions. By establishing direct, private links, organizations can enable VPCs to exchange traffic securely using private IP addresses, supporting multi-tenant and hybrid cloud architectures.

Administrators configure peering connections, update route tables for proper traffic flow, and implement security groups and network ACLs to control access between peered VPCs. Encryption and monitoring are often required to ensure data privacy and operational visibility.

Benefits include scalable network expansion, isolation of workloads, and low-latency connectivity without the need for VPNs or public internet exposure. Inter-VPC peering is cost-effective and simplifies connectivity for distributed applications and services.

While peering offers robust connectivity, misconfiguration can lead to security gaps or routing issues. Alternatives may include VPNs, dedicated interconnects, or service mesh architectures for more complex requirements.
