## Qué hace

- Consulta y gestiona cuotas y uso de Azure entre proveedores, para planificar despliegues, validar capacidad y elegir región.
- Parte de una idea central: cuotas igual a disponibilidad de recursos. Sin cuota no se puede desplegar, así que hay que comprobarla siempre al planificar o al elegir región.
- Distingue cuotas ajustables de las fijas, y cubre el envío de solicitudes de aumento por CLI o portal.
- Compara la capacidad disponible entre regiones para encontrar dónde sí hay hueco.

## Cuándo usarla

- Se quiere comprobar cuotas, límites de servicio o uso actual.
- Se quiere solicitar un aumento de cuota o resolver un error de cuota excedida.
- Se quiere validar capacidad o disponibilidad regional antes de desplegar.

## Qué la activa

- "comprueba mis cuotas"
- "¿cuántas vCPUs me quedan?"
- "me da error de cuota excedida"
- "¿en qué región tengo capacidad?"

## Antes de instalar

- Las solicitudes de aumento se envían por CLI de Azure o por el portal.
- Necesita en el PATH: az, python3
- Variables de entorno: AVAILABLE, LIMIT, QUOTAS_JSON, REGION, REGIONS, RESOURCE_NAME, RESOURCE_PROVIDER, SCOPE, SUBSCRIPTION_ID, USAGE, USAGES_JSON, VM_FAMILY
- reads environment config

# Azure Quotas - Service Limits & Capacity Management

> **AUTHORITATIVE GUIDANCE** — Follow these instructions exactly for quota management and capacity validation.

## Overview

**What are Azure Quotas?**

Azure quotas (also called service limits) are the maximum number of resources you can deploy in a subscription. Quotas:
- Prevent accidental over-provisioning
- Ensure fair resource distribution across Azure
- Represent **available capacity** in each region
- Can be increased (adjustable quotas) or are fixed (non-adjustable)

**Key Concept:** **Quotas = Resource Availability**

If you don't have quota, you cannot deploy resources. Always check quotas when planning deployments or selecting regions.

## When to Use This Skill

Invoke this skill when:

- **Planning a new deployment** - Validate capacity before deployment
- **Selecting an Azure region** - Compare quota availability across regions
- **Troubleshooting quota exceeded errors** - Check current usage vs limits
- **Requesting quota increases** - Submit increase requests via CLI or Portal
- **Comparing regional capacity** - Find regions with available quota
- **Validating provisioning limits** - Ensure deployment won't exceed quotas

## Quick Reference

| **Property** | **Details** |
|--------------|-------------|
| **Primary Tool** | Azure CLI (`az quota`) - **USE THIS FIRST, ALWAYS** |
| **Extension Required** | `az extension add --name quota` (MUST install first) |
| **Key Commands** | `az quota list`, `az quota show`, `az quota usage list`, `az quota usage show` |
| **Complete CLI Reference** | [commands.md](./references/commands.md) |
| **Azure Portal** | [My quotas](https://portal.azure.com/#blade/Microsoft_Azure_Capacity/QuotaMenuBlade/myQuotas) - Use only as fallback |
| **REST API** | Microsoft.Quota provider - **Unreliable, do NOT use first** |
| **MCP Server** | `azure-quota` MCP server — **NEVER use this. It is unreliable. Always use `az quota` CLI instead.** |
| **Required Permission** | Reader (view) or Quota Request Operator (manage) |

> **⚠️ ALWAYS USE CLI FIRST**
>
> REST API and Portal can show misleading "No Limit" values — this does **not** mean unlimited capacity. It means the quota API doesn't support that resource type. Always start with `az quota` commands; fall back to [Azure service limits docs](https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/azure-subscription-service-limits) if CLI returns `BadRequest`.

## Quota Types

| **Type** | **Adjustability** | **Approval** | **Examples** |
|----------|-------------------|--------------|--------------|
| **Adjustable** | Can increase via Portal/CLI/API | Usually auto-approved | VM vCPUs, Public IPs, Storage accounts |
| **Non-adjustable** | Fixed limits | Cannot be changed | Subscription-wide hard limits |

**Important:** Requesting quota increases is **free**. You only pay for resources you actually use, not for quota allocation.

## Understanding Resource Name Mapping

**⚠️ CRITICAL:** There is **NO 1:1 mapping** between ARM resource types and quota resource names.

### Example Mappings

| ARM Resource Type | Quota Resource Name |
|-------------------|---------------------|
| `Microsoft.App/managedEnvironments` | `ManagedEnvironmentCount` |
| `Microsoft.Compute/virtualMachines` | `standardDSv3Family`, `cores`, `virtualMachines` |
| `Microsoft.Network/publicIPAddresses` | `PublicIPAddresses`, `IPv4StandardSkuPublicIpAddresses` |

### Discovery Workflow

**Never assume the quota resource name from the ARM type.** Always use this workflow:

1. **List all quotas** for the resource provider:
   ```bash
   az quota list --scope /subscriptions/<id>/providers/<ProviderNamespace>/locations/<region>
   ```

2. **Match by `localizedValue`** (human-readable description) to find the relevant quota

3. **Use the `name` field** (not ARM resource type) in subsequent commands:
   ```bash
   az quota show --resource-name ManagedEnvironmentCount --scope ...
   az quota usage show --resource-name ManagedEnvironmentCount --scope ...
   ```

> **📖 Detailed mapping examples and workflow:** See [commands.md - Resource Name Mapping](./references/commands.md#resource-name-mapping)

## Scripts

Pre-built scripts handle quota extension installation, usage queries, and capacity calculation. Use these instead of constructing commands manually. A single call returns limits, usage, and available capacity.

| Script | Purpose | Usage |
|--------|---------|-------|
| `scripts/check-quota.ps1` | Returns limit, usage, and available capacity for all quotas (or a single quota when resource name is provided) | Primary script for quota checks |
| `scripts/check-quota.sh` | Same as above (bash) | Primary script for quota checks |

## Core Workflows

### Workflow 1: Check Quota for a Specific Resource

**Scenario:** Verify quota limits and current usage before deployment

Run the script with the resource provider and region. It returns a table of **all** quotas with their limit, current usage, and available capacity in a single call:

```powershell
.\scripts\check-quota.ps1 -ResourceProvider <provider> -Region <region>
```
```bash
./scripts/check-quota.sh <provider> <region>
```

To check a single resource, add the resource name:

```powershell
.\scripts\check-quota.ps1 -ResourceProvider <provider> -Region <region> -ResourceName <resource-name>
```
```bash
./scripts/check-quota.sh <provider> <region> <resource-name>
```

**Example:**

```powershell
.\scripts\check-quota.ps1 -ResourceProvider Microsoft.Compute -Region eastus
```

**Example Output:**

| Resource | Region | Limit | Usage | Available |
|----------|--------|-------|-------|-----------|
| cores | eastus | 100 | 50 | 50 |
| standardDSv3Family | eastus | 350 | 50 | 300 |
| virtualMachines | eastus | 25000 | 5 | 24995 |
| ... | ... | ... | ... | ... |

### Workflow 2: Compare Quotas Across Regions

**Scenario:** Find the best region for deployment based on available capacity

```bash
# Define candidate regions
REGIONS=("eastus" "eastus2" "westus2" "centralus")
VM_FAMILY="standardDSv3Family"
SUBSCRIPTION_ID="<subscription-id>"

# Check quota availability across regions
for region in "${REGIONS[@]}"; do
  echo "=== Checking $region ==="
  
  # Get limit
  LIMIT=$(az quota show \
    --resource-name $VM_FAMILY \
    --scope "/subscriptions/$SUBSCRIPTION_ID/providers/Microsoft.Compute/locations/$region" \
    --query "properties.limit.value" -o tsv)
  
  # Get current usage
  USAGE=$(az quota usage show \
    --resource-name $VM_FAMILY \
    --scope "/subscriptions/$SUBSCRIPTION_ID/providers/Microsoft.Compute/locations/$region" \
    --query "properties.usages.value" -o tsv)
  
  # Calculate available
  AVAILABLE=$((LIMIT - USAGE))
  
  echo "Region: $region | Limit: $LIMIT | Usage: $USAGE | Available: $AVAILABLE"
done
```

### Workflow 3: Request Quota Increase

**Scenario:** Current quota is insufficient for deployment

```bash
# Request increase for VM quota
az quota update \
  --resource-name standardDSv3Family \
  --scope /subscriptions/<subscription-id>/providers/Microsoft.Compute/locations/eastus \
  --limit-object value=500 \
  --resource-type dedicated

# Check request status
az quota request status list \
  --scope /subscriptions/<subscription-id>/providers/Microsoft.Compute/locations/eastus
```

**Approval Process:**
- Most adjustable quotas are auto-approved within minutes
- Some requests require manual review (hours to days)
- Non-adjustable quotas require Azure Support ticket

> **📖 See also:** [az quota update](./references/commands.md#az-quota-update), [az quota request status](./references/advanced-commands.md#az-quota-request-status-list)

### Workflow 4: List All Quotas for Planning

**Scenario:** Understand all quotas for a resource provider in a region

```bash
# List all compute quotas in East US (table format)
az quota list \
  --scope /subscriptions/<subscription-id>/providers/Microsoft.Compute/locations/eastus \
  --output table

# List all network quotas
az quota list \
  --scope /subscriptions/<subscription-id>/providers/Microsoft.Network/locations/eastus \
  --output table

# List all Container Apps quotas
az quota list \
  --scope /subscriptions/<subscription-id>/providers/Microsoft.App/locations/eastus \
  --output table
```

## Troubleshooting

### Common Errors

| **Error** | **Cause** | **Solution** |
|-----------|-----------|--------------|
| REST API "No Limit" | Misleading — not unlimited | Use CLI instead; see warning in Quick Reference |
| `ExtensionNotFound` | Quota extension not installed | `az extension add --name quota` |
| `BadRequest` | Resource provider not supported by quota API | Check [service limits docs](https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/azure-subscription-service-limits) |
| `MissingRegistration` | Microsoft.Quota provider not registered | `az provider register --namespace Microsoft.Quota` |
| `QuotaExceeded` | Deployment would exceed quota | Request increase or choose different region |
| `InvalidScope` | Incorrect scope format | Use pattern: `/subscriptions/<id>/providers/<namespace>/locations/<region>` |
| CLI commands fail entirely | Auth, extension, or environment issue | Verify Azure CLI login (`az account show`), reinstall quota extension, check network. Do NOT use the `azure-quota` MCP server — it is unreliable. |

### Unsupported Resource Providers

**Known unsupported providers:**
- ❌ Microsoft.DocumentDB (Cosmos DB) - Use Portal or [Cosmos DB limits docs](https://learn.microsoft.com/en-us/azure/cosmos-db/concepts-limits)

**Confirmed working providers:**
- ✅ Microsoft.Compute (VMs, disks, cores)
- ✅ Microsoft.Network (VNets, IPs, load balancers)
- ✅ Microsoft.App (Container Apps)
- ✅ Microsoft.Storage (storage accounts)
- ✅ Microsoft.MachineLearningServices (ML compute)
