Setup

The setup phase gets your base infrastructure running on both clouds. After this, you’ll have a working VPC on AWS and GCP with compute instances ready, plus the Direct Connect Gateway waiting for the interconnect link.

What gets created

Roughly 20 resources across AWS and GCP:

• AWS: VPC, private subnet, Virtual Private Gateway, route table, EC2 instance (t3.micro), 3 VPC interface endpoints for SSM, DX Gateway + association
• GCP: VPC network, subnet, firewall rules (ICMP, SSH, IAP), GCE instance (e2-micro)

Steps in this section

1. Configure variables — edit terraform.tfvars with your project details
2. Apply Terraform — create the base infrastructure
3. GCP prep — enable the Network Connectivity API and service agent
