Hybrid VPN ConnectivityAWS Architecture Template

On-premises networks attach via site-to-site VPN to a Transit Gateway that routes into app and data VPCs with hybrid DNS.

Why this architecture works

  • Terminating VPN on Transit Gateway (not per-VPC) means one tunnel set serves every VPC
  • Separate app and data VPCs let you expose application subnets to on-prem while keeping databases restricted
  • Route 53 resolver endpoints give on-prem and cloud workloads consistent name resolution both ways
  • Non-overlapping CIDR planning up front avoids the NAT contortions that plague hybrid retrofits
  • Tunnel-state and bandwidth alarms in CloudWatch detect degraded VPN paths before users report outages

From template to running infrastructure

  1. Open this template in the CloudForge visual designer (free account, no credit card).
  2. Customize resources, names, and connections on the drag-and-drop canvas — or ask Vani, the AI architect, to adapt it.
  3. Generate production-ready Terraform or CloudFormation in one click.
  4. Review the plan diff and security scan, then deploy with human approval.
