☁️ Cloud Architecture — Multi-Cloud Networking Patterns Demo

• Terraform 1.5+
• AWS CLI configured with appropriate credentials
• Azure CLI (`az login`)
• GCP CLI (`gcloud auth application-default login`)
• Network permissions in all three clouds

# Initialize Terraform with all three providers
cd terraform/
terraform init

# Deploy AWS-Azure VPN connection
terraform plan -var-file=../examples/aws-azure-vpn.tfvars
terraform apply -var-file=../examples/aws-azure-vpn.tfvars

# Validate connectivity
python ../scripts/connectivity_validator.py
