# Apply Fast scaling with the UI

This topic describes how to apply Fast scaling using the UI.

To enable and configure regular draining using YAML, see [Spike protection](/v1/docs/apply-fast-scaling-with-yaml#spike-protection).

You apply Fast scaling to a workload using the Fast scaling tab (“tab”) of the workload recommendation drawer (“drawer”).

To see the drawer, click anywhere in the workload row in the **Clusters > Workloads** tab.

#### Configure draining mechanism

After you’ve applied Fast scaling to a workload, you can change the draining mechanism from accelerated (default) to regular using YAML. For more information about the draining mechanisms, see [Node draining mechanisms](/v1/docs/how-fast-scaling-works#node-draining-mechanisms).

#### Fast scaling tab

The following figure illustrates the Fast scaling tab of the drawer:

The tab shows the current node boot time versus the optimized boot time after Fast scaling is active.

**Prerequisites:**

- The Compute agent is installed in the cluster. For more information, see [Install Kubernetes resource optimization components](/v1/docs/install-kubernetes-resource-optimization-components). If you attempt to apply Fast scaling before the Compute agent is installed, you’ll see a message showing how you can install it directly from the drawer.

**To apply Fast scaling to a workload from the UI:**

1. From the **Clusters > Workloads** tab, click anywhere in the row of a workload.

> [!NOTE]
> Tip
> 
> You can filter to see only the workloads with recommendations by turning on **Recommendations only**.

The workload recommendation drawer is displayed.
2. Select the **Fast scaling** tab.
3. Turn on the protection.
4. Click **Apply to workload**, then confirm.

After you apply Fast scaling, the drawer values remain blurred while application is in progress.

### Remove Fast scaling from a workload

After Fast scaling is active on a workload, you can remove the protection.

**To remove Fast scaling from a workload:**

1. From the **Clusters > Workloads** tab, find the workload and click anywhere in its row. The workload tab is displayed in the drawer.
2. Turn the protection off.
3. Click **Apply to workload**, then confirm.

A confirmation message is displayed.
