+
+> When Autoscale IOPS is enabled for Azure Database for MySQL (Flexible Server), the IOPS (Input/Output Operations Per Second) automatically scale both up and down based on your workload demands. <br/>
+> - During `high demand`, the system `increases IOPS` to maintain performance.
+> - During `low demand`, it `scales down` to reduce resource usage and cost.
+
+## How to provision 
+
+1. Go to the [Azure Portal](https://portal.azure.com/)
+2. Search for `Azure Database for MySQL Flexible Server` in the search bar.
+3. Click `Create`.
+4. Choose your subscription, resource group, and server name.
+5. Select the region, MySQL version, and workload type (e.g., Development, Production).

+
+## How to enable IOPS
+
+1. Go to the [Azure Portal](https://portal.azure.com/)
+2. Select the server you want to configure.
+3. In the left-hand menu, go to `Settings > Compute + Storage.`
+4. In the IOPS section, select the option `Autoscale IOPS`
+5. Click `Save` to apply the changes.

+## How to Monitor IOPS Scaling
+
+> How I know if the IOPS have scaled up or down when the server's using the autoscale IOPS feature? You can use the `metrics available in Azure Monitor`. 
+
+1. **Use Azure Monitor Metrics**:
+   - Go to your server in the [Azure portal](https://portal.azure.com/)
+   - Go to the `Monitoring` section and select `Metrics`.
+

+
+   - Choose the ` Storage IO` metric (both percent and count).
+

+
+   - Set a `custom time range` to observe trends over time.
+
+2. **Look for Scaling Patterns**:
+   - If you see `sudden increases or decreases` in the IOPS metric that correlate with workload changes, this indicates that autoscale IOPS has adjusted the performance level.
+   - You can also monitor `IO utilization percentage` to see how close your server is to its current IOPS limit.
+3. **Enable Alerts (Optional)**: You can set up `alerts` in Azure Monitor to notify you when IOPS usage crosses certain thresholds, which can help you track scaling events in real time.
