# Recipe Selection

Choose the deployment recipe based on project needs and existing tooling.

## ⛔ Special Cases: Detect First

**Before selecting a recipe, check for these special project types:**

| Project Type | Detection | Recipe Selection |
|--------------|-----------|------------------|
| **.NET Aspire** | `*.AppHost.csproj` or `Aspire.Hosting` package | **AZD (auto via `azd init --from-code`)** → [aspire.md](aspire.md) |

> 💡 **Tip:** .NET Aspire projects always use AZD recipe with auto-generated configuration. Do not manually select recipe or create artifacts.

## Quick Decision

**Default: AZD** unless specific requirements indicate otherwise.

> 💡 **Tip:** azd supports both Bicep and Terraform as IaC providers. When Terraform is mentioned for Azure deployment, **default to azd+Terraform** for the best developer experience.

## Decision Criteria

| Choose | When |
|--------|------|
| **AZD (Bicep)** | New projects, multi-service apps, want simplest deployment (`azd up`) |
| **AZD (Terraform)** | **DEFAULT for Terraform** - Want Terraform IaC + azd simplicity, Azure deployment with Terraform |
| **AZCLI** | Existing az scripts, need imperative control, custom pipelines, AKS |
| **Bicep** | IaC-first approach, no CLI wrapper needed, direct ARM deployment |
| **Terraform** | Multi-cloud deployments (non-Azure-first), complex TF workflows incompatible with azd, explicitly requested |

## Auto-Detection

| Found in Workspace | Suggested Recipe |
|--------------------|------------------|
| `azure.yaml` with `infra.provider: terraform` | AZD (Terraform) |
| `azure.yaml` (Bicep or no provider specified) | AZD (Bicep) |
| `*.tf` files (no azure.yaml) | **AZD (Terraform) - DEFAULT** (unless multi-cloud) |
| `infra/*.bicep` (no azure.yaml) | Bicep or AZCLI |
| Existing `az` scripts | AZCLI |
| None | AZD (Bicep) - default |

## Recipe Comparison

| Feature | AZD (Bicep) | AZD (Terraform) | AZCLI | Bicep | Terraform |
|---------|-------------|-----------------|-------|-------|-----------|
| Config file | azure.yaml | azure.yaml + *.tf | scripts | *.bicep | *.tf |
| IaC language | Bicep | Terraform | N/A | Bicep | Terraform |
| Deploy command | `azd up` | `azd up` | `az` commands | `az deployment` | `terraform apply` |
| Dockerfile gen | Auto | Auto | Manual | Manual | Manual |
| Environment mgmt | Built-in | Built-in | Manual | Manual | Workspaces |
| CI/CD gen | Built-in | Built-in | Manual | Manual | Manual |
| Multi-cloud | No | Yes | No | No | Yes |
| Learning curve | Low | Low-Medium | Medium | Medium | Medium |

## Record Selection

Document in `.azure/deployment-plan.md`:

```markdown
## Recipe: AZD (Terraform)

**Rationale:**
- Team has Terraform expertise
- Want multi-cloud IaC flexibility
- But prefer azd's simple deployment workflow
- Multi-service app (API + Web)
```

Or for pure Terraform:

```markdown
## Recipe: Terraform

**Rationale:**
- Multi-cloud deployment (AWS + Azure)
- Complex Terraform modules incompatible with azd conventions
- Existing Terraform CI/CD pipeline
```
