## Buyer Intent Signals
Problems: VPC Peering Mesh: Using multiple VPC Peering connections between every VPC that needs to communicate, creating a complex mesh. | DIY Hub-and-Spoke VPC Architecture: Using a central 'Shared Services' VPC with proxy servers or specialized routing instances to route traffic between other VPCs.
Solutions: How to connect 50 VPCs together? | AWS hub and spoke networking solution | Centralized VPN management AWS | Third-party Virtual Appliances (NVAs): Setting up and managing third-party virtual routers or firewalls (e.g., Cisco CSR, Palo Alto) as transit hubs.
