| 2 | +Azure MySQL Flexible Server Auto IOPS Enabler |
| 3 | +
|
| 4 | +This script connects to Azure using the Azure CLI and Azure REST API to: |
| 5 | +1. Retrieve the current subscription ID. |
| 6 | +2. List all Resource Groups in the current subscription. |
| 7 | +3. List all MySQL Flexible Servers in each resource group. |
| 8 | +4. Skip resource groups with no MySQL Flexible Servers. |
| 9 | +5. Check if each server is eligible for Auto IOPS scaling (only GeneralPurpose or BusinessCritical tiers). |
| 10 | +6. Optionally enable Auto IOPS scaling if not already enabled. |
| 11 | +7. Print a summary of which servers were updated or skipped. |
