## Task 2: Scale Azure Virtual Machine Scale Sets
In this task, you scale the virtual machine scale set using a xxxxx .
In this task, you scale the virtual machine scale set using a custom scale rule.
1. Select **Go to resource** or search for and select the **vmss1** scale set.
1. Choose **Scaling** from the menu on the left-hand side of the scale set window.
1. Notice the **Scale mode** can be **Scale based on metrics** or **Scale to a specific instance count**. In scale sets with a small number of VM instances, increasing or decresing the instance count may be best. In scale sets with a large number of VM instances, scaling based on metrics may be more appropriate.
1. Select the button to **Custom autoscale**.
1. Let's create a rule that increases the number of VM instances in a scale set when the average CPU load is greater than 70% over a 10-minute period. When the rule triggers, the number of VM instances is increased by 20%. Click **Add** after making your selections.
| Setting | Value |
| --- | --- |
| Metric source | **Current resource (vmss1)** |
| Metric namespace | **Virtual Machine Host** |
| Metric name | **Percentage CPU** (review your other choices) |
| Operator | **Greater than** |
| Metric threshold to trigger scale action | **70** |
| Duration (minutes) | **10** |
| Time grain statistic | **Average** |
| Operation | **Increase percent by** (review other choices) |
| Cool down (minutes) | **5** |
| Percentage | **20** |
