# Clean Up Resources


CloudFormation makes it easy to clean up resources that the stack created. When you delete the stack, all resources that the stack created are deleted.

**To delete resources that the template created**
+ Open the CloudFormation console, select the root stack that you created earlier, choose **Actions**, **Delete**.

  The **Status** of the root stack you created earlier and the associated nested stacks update to **DELETE\$1IN\$1PROGRESS**.

You may choose to delete the prerequisites you created for the Ethereum network.

**Delete the VPC**
+ Open the Amazon VPC console, select the VPC you created earlier and then choose **Actions**, **Delete VPC**. This also deletes the subnets, security groups, and the NAT gateway associated with the VPC.

**Delete the IAM role and EC2 instance profile**
+ Open the IAM console and choose **Roles**. Select the role for ECS and the role for EC2 that you created earlier and choose **Delete**.

**Terminate the EC2 instance for the bastion host**
+ Open the Amazon EC2 dashboard, choose **Running instances**, select the EC2 instance that you created for the bastion host, choose **Actions**, **Instance State**, **Terminate**.
