# Adding and restricting Amazon EC2 instances for AWS Marketplace
<a name="single-ib-instance-types"></a>

As an AWS Marketplace seller, you can manage which instances buyers can use. You can add a new instance for your product that buyers can use. Similarly, if you want to prevent new buyers from using your product from a specific instance, you can restrict the instance. 

For more information about the Amazon EC2 instance types, see [Available instance types](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html#AvailableInstanceTypes) in the *Amazon EC2 User Guide*.

The following sections explain how to add and restrict instances.

## Adding an instance
<a name="single-ib-adding-instance-types"></a>

You can add a new instance that buyers can use as a EC2 Image Builder component.

**To add an instance**

1. Open the AWS Marketplace Management Portal at [https://aws.amazon.com/marketplace/management/tour/](https://aws.amazon.com/marketplace/management/tour/), and then sign in to your seller account.

1. Go to the [https://aws.amazon.com/marketplace/management/products/server](https://aws.amazon.com/marketplace/management/products/server) page, and on the **Current server product** tab, select the product that you want to modify.

1. From the **Request changes** dropdown, choose **Add instance**.

1. Select an instance architecture.

1. Select the instance types that you want to add from the list of available instances.

1. Choose **Submit request** to submit your request for review.

1. Verify that the **Requests** tab shows the **Request status** as **Under review**. When the request completes, the status becomes **Succeeded**.
**Note**  
If your current pricing model is not free or uses a Bring Your Own License (BYOL) model, you must also add prices. 
 If you created an **Add instance** with a price for the new instance or **Update pricing** to increase a price, you can’t use self-service to **Add instance** in the 90 days starting from the day you made the change. To make these changes, contact the [AWS Marketplace Seller Operations team](https://aws.amazon.com/marketplace/management/contact-us/).
When you add support for a new instance type, customers already subscribed to private offers for your product won't be able to launch the newly added instance automatically. You must create another private offer with the instance you want customers to access. After accepting the new offer, customers can launch the newly added instance. Customers who subscribe to your product at a future date can also launch the instance, as long as the instance is included in the private offer. For more information about how to create a new private offer, see [Amending agreements in AWS Marketplace](private-offers-upgrades-and-renewals.md) later in this guide.

## Restricting an instance
<a name="single-ib-restricting-instance-types"></a>

To prevent new buyers from using an instance, you can restrict the instance. You can add the instance back at a later time, if needed. Existing users of EC2 Image Builder components on the restricted instance can continue to use the product from the Region for the length of their subscriptions.

**To restrict an instance**

1. Open the AWS Marketplace Management Portal at [https://aws.amazon.com/marketplace/management/tour/](https://aws.amazon.com/marketplace/management/tour/), and then sign in to your seller account.

1. Go to the [https://aws.amazon.com/marketplace/management/products/server](https://aws.amazon.com/marketplace/management/products/server) page, and on the **Current server product** tab, select the product that you want to modify.

1. From the **Request changes** dropdown, choose **Restrict instance**.

1. Select the instances that you want to restrict, and choose **Restrict**.

1. Choose **Submit change request** to submit your request for review.

1. Verify that the **Requests** tab shows the **Request status** as **Under review**. When the request completes, the status becomes **Succeeded**.
**Note**  
If the check box is shaded, this means the instance is associated with one to several versions as a recommended instance type. To restrict such instances, use **Update versions** to choose a different recommended instance type. After the change requests complete and the instance you want to restrict is no longer a recommended instance type, you can return to **Restrict instance** to restrict your chosen instance.
