Example Concept: In a multicloud VPC setup, use a hub-and-spoke network topology where each cloud provider's VPC acts as a spoke connected to a central hub. This hub can be a dedicated network appliance or a cloud-native service that manages cross-cloud traffic. Implement consistent CIDR block allocations to avoid IP conflicts, and use VPNs or dedicated interconnects for secure, low-latency connectivity. Employ centralized identity and access management (IAM) and logging to ensure unified security and monitoring across all environments.
