# Stand-alone VPC

> The Stack template creates a brand-new VPC dedicated to the install.

## Deploying an Example App

If you're still designing your BYOC architecture, it is helpful to deploy a sample app. For the Stand-Alone VPC architecture, see [`eks-simple-auto`](https://github.com/nuonco/example-app-configs/tree/main/eks-simple-auto) in `nuonco/example-app-configs`.

## Overview

When the customer deploys the Nuon-generated CloudFormation/Bicep or Terraform template that [you provide](/guides/install-configs), a fresh VPC is provisioned alongside the Runner and its permissions, all inside the customer's account.

## App config

Each install supports two deployment formats: a Nuon-generated CloudFormation/Bicep template and the Terraform modules Nuon publishes at [`install-stacks`](https://github.com/nuonco/install-stacks) (AWS and GCP subfolders).

### CloudFormation/Bicep

The vendor's `stack.toml` references nested templates. Set `type` to the cloud's native format — `aws-cloudformation` or `azure-bicep` — and point `vpc_nested_template_url` at the matching template.

**AWS (CloudFormation)** — point at `vpc/eks/default` to create a new VPC:

```toml stack.toml theme={null}
type = "aws-cloudformation"

vpc_nested_template_url    = "https://nuon-artifacts.s3.us-west-2.amazonaws.com/aws-cloudformation-templates/v0.4.0/vpc/eks/default/stack.yaml"
runner_nested_template_url = "https://nuon-artifacts.s3.us-west-2.amazonaws.com/aws-cloudformation-templates/v0.4.0/runner/asg/stack.yaml"
```

The customer deploys via the CloudFormation Quick Create form (or `aws cloudformation deploy`) — no further input is needed beyond account and region.

**Azure (Bicep)** — point at the `vnet.json` and `runner.json` templates in [`install-stacks/azure`](https://github.com/nuonco/install-stacks/tree/main/azure):

```toml stack.toml theme={null}
type = "azure-bicep"

vpc_nested_template_url    = "https://raw.githubusercontent.com/nuonco/install-stacks/main/azure/vnet.json"
runner_nested_template_url = "https://raw.githubusercontent.com/nuonco/install-stacks/main/azure/runner.json"
```

See [`aca-simple`](https://github.com/nuonco/example-app-configs/tree/main/aca-simple) for a complete Bicep example.

### Terraform

Nuon publishes Terraform modules for both AWS and GCP at [`install-stacks`](https://github.com/nuonco/install-stacks) that provision the same resources. The customer clones (or wraps) their cloud's module and runs `terraform apply` against it. See [Customizing Terraform Stack Templates](/guides/customizing-terraform-stack-templates) if you need to fork.

### Sandbox

The [Sandbox](/concepts/sandboxes) runs after the Stack and provisions the app's compute layer inside the new VPC. It picks up the VPC by reading the Stack's outputs:

```toml sandbox.toml theme={null}
[vars]
region = "{{.nuon.install_stack.outputs.region}}"
vpc_id = "{{.nuon.install_stack.outputs.vpc_id}}"
```
