# Agent pool

When you create agent pools to run Azure Kubernetes (AKS) workloads, you create groups of agents available to a pipeline. When you run the pipeline, the pipeline selects the agent that best meets the performance demands of that pipeline.

Agent pools can be [autoscaled](broken://pages/rBSCO4qR3H9aNaiwXq5f) when the **Enable Autoscaling** option is selected in the DuploCloud Portal. Each agent pool contains nodes backed by virtual host machines.

Use the DuploCloud Portal **Hosts** page to create and edit Azure agent pools.

## Creating an agent pool

Create an Azure agent pool for an existing Host in the DuploCloud Portal:

1. Select **Devops** -> **Hosts** from the navigation menu.

3. Click **Add**. The **Add Azure Agent Pool** page is displayed.
4. Provide inputs for the **Instance Type**, **Min Capacity**, and **Max Capacity** fields.
