<a name="create-compute-environment-unmanaged-ec2"></a>

Complete the following steps to create an unmanaged compute environment using Amazon Elastic Compute Cloud (Amazon EC2) resources.

****

1. Open the AWS Batch console at [https://console.aws.amazon.com/batch/](https://console.aws.amazon.com/batch/).

1. From the navigation bar, select the AWS Region to use.

1. On the **Compute Environments** page, choose **Create**.

1. Configure the environment.

   1. For **Compute environment configuration**, choose **Amazon Elastic Compute Cloud (Amazon EC2)**.

   1. For **Orchestration type**, choose **Unmanaged**.

1. For **Name**, specify a unique name for your compute environment. The name can be up to 128 characters in length. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (\$1).

1. For **Service role**, choose a role that lets the AWS Batch service make calls to the required AWS API operations on your behalf.
**Note**  
You can't use `AWSServiceRoleForBatch` for unmanaged compute environments.

1. For **Maximum vCPUs**, choose the maximum number of vCPUs that your compute environment can scale out to, regardless of job queue demand.

1. (Optional) Expand **Tags**. To add a tag, choose **Add tag**. Then, enter a **Key** name and optional **Value**. Choose **Add tag**. For more information, see [Tag your AWS Batch resources](using-tags.md).

1. Choose **Next page**.

1. For **Review**, review the configuration steps. If you need to make changes, choose **Edit**. When you're finished, choose **Create compute environment**.
