# Azure Storage Services

## Services

| Service | Use When | MCP Tools | CLI |
|---------|----------|-----------|-----|
| Blob Storage | Objects, files, backups, static content | `azure__storage` | `az storage blob` |
| File Shares | SMB file shares, lift-and-shift | - | `az storage file` |
| Queue Storage | Async messaging, task queues | - | `az storage queue` |
| Table Storage | NoSQL key-value (consider Cosmos DB) | - | `az storage table` |
| Data Lake | Big data analytics, hierarchical namespace | - | `az storage fs` |

## MCP Server (Preferred)

When Azure MCP is enabled:

- `azure__storage` with command `storage_account_list` - List storage accounts
- `azure__storage` with command `storage_container_list` - List containers in account
- `azure__storage` with command `storage_blob_list` - List blobs in container
- `azure__storage` with command `storage_blob_get` - Download blob content
- `azure__storage` with command `storage_blob_put` - Upload blob content

**If Azure MCP is not enabled:** Run `/azure:setup` or enable via `/mcp`.

## CLI Fallback

```bash
# List storage accounts
az storage account list --output table

# List containers
az storage container list --account-name ACCOUNT --output table

# List blobs
az storage blob list --account-name ACCOUNT --container-name CONTAINER --output table

# Download blob
az storage blob download --account-name ACCOUNT --container-name CONTAINER --name BLOB --file LOCAL_PATH

# Upload blob
az storage blob upload --account-name ACCOUNT --container-name CONTAINER --name BLOB --file LOCAL_PATH
```

## Storage Account Tiers

| Tier | Use Case | Performance |
|------|----------|-------------|
| Standard | General purpose, backup | Milliseconds |
| Premium | Databases, high IOPS | Sub-millisecond |

## Blob Access Tiers

| Tier | Access Frequency | Cost |
|------|-----------------|------|
| Hot | Frequent | Higher storage, lower access |
| Cool | Infrequent (30+ days) | Lower storage, higher access |
| Cold | Rare (90+ days)
