| 11 | + |
| 12 | +> Using [Python 3.7+](https://www.python.org/downloads/source/) |
| 13 | +
|
| 14 | +> [!NOTE] |
| 15 | +> Enable Autoscale IOPS via REST API, as now this is the only way to automate enabling Autoscale IOPS since, Azure CLI and PowerShell do not support this setting yet. |
| 16 | +
|
| 17 | +> [!IMPORTANT] |
| 18 | +> Autoscale IOPS is `only available` for the `General Purpose` and `Business Critical tiers`. `Burstable tier` (B-series) servers (e.g., B1ms) `do not support autoscale IOPS`. |
| 19 | +
|
| 20 | +## Pre-requisites |
| 21 | + |
| 22 | +- Install azure-identity with: `py -m pip install azure-identity requests` |

| 25 | + |
| 26 | +- [Install Azure CLI](https://learn.microsoft.com/en-us/cli/azure/install-azure-cli) to work with both Terraform and Azure commands. |

| 30 | +## By Resource Group |
| 31 | + |
| 32 | +> - Automatically retrieves your **Azure subscription ID** using the Azure CLI. <br/> |
| 33 | +> - Prompts you only for the **resource group name**. <br/> |
| 34 | +> - Lists all MySQL Flexible Servers in that resource group. <br/> |
| 35 | +> - Sends a `PATCH request`` to enable `autoIoScaling` for each server using the `Azure REST API` |
| 36 | +
|
| 37 | +Review [the script](./enable_autoscale_iops_byRG.py), and download it to your local machine. |
| 38 | + |
| 39 | +## Across a Subscription |
| 40 | + |
| 41 | +> You can also enable autoscale IOPS across an entire subscription, it requires: <br/> |
| 42 | +> - Listing all MySQL Flexible Servers in the subscription. <br/> |
| 43 | +> - For each server, retrieving its resource group. <br/> |
| 44 | +> - Applying the update if the server is in a supported tier (General Purpose or Business Critical). <br/> |
| 45 | +
|
| 46 | +Review [the script](./enable_autoscale_iops.py), and download it to your local machine. |
| 47 | + |
| 48 | +## How to execute it Azure CLI Script to Enable Autoscale IOPS |
| 49 | + |
| 50 | +1. Download [the script](./enable_autoscale_iops.py) to your local machine or a cloud shell environment. |
| 51 | +2. Make sure you're logged in: `az login` |
| 52 | +4. Run the script: `py enable_autoscale_iops.py` |
| 53 | + |
| 54 | +> Example: enabling Autoscale IOPS on three different servers, each hosted in a separate resource group but under the same subscription. |
