# 2. Create Scaling Policy

{% hint style="info" %}
**Scaling Policy** is used to scale based on metrics with further information about the rules that users give to decide how many instances are added or removed from the group during an in/out scaling execution.
{% endhint %}

**Step 1:** Go to **Autoscaling** page > **Autoscale Policy** > Select **Create Policy**.

**Step 2:** A new dialog box will appear. On **Policy type**, select **Scaling.**

**Step 3:** A new dialog box will appear with three more options. Users configure as following:

| Field           | Description                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         |

| **Number**      | <p>Depending on the <strong>Change type</strong> field, the value will have different meanings:</p><p><strong>Exact capacity:</strong> The new capacity of the Autoscale Group (Must be a positive integer).</p><p><strong>Change in capacity:</strong> The number of Instances added/removed from the Autoscale Group (Must be a positive integer).</p><p><strong>Change in percentage:</strong> The current capacity percentage of Autoscale Group to calculate the number of Instances to be added or removed.</p><p><em>Eg: The value of Number is 50%, the capacity of Autoscale Group is 4, the event is Scale out, then when a Scale out action is performed, the number of Instances added is 50% of 4, and the new capacity is 6.</em></p> |

**Step 4:** Click **Create**.

The system will confirm and create a new policy.
