Amazon DevPay and Your Amazon EC2 AMIs
You can use Amazon DevPay to sell an AMI that you create to other Amazon EC2 users. Amazon DevPay creates and manages the order pipeline and billing system for you. Your customers sign up for your AMI, and Amazon DevPay automatically meters their usage of Amazon EC2, bills them based on the pricing you set, and collects their payments.
An AMI that you sell to other Amazon EC2 users through Amazon DevPay is called a paid AMI. Amazon EC2 also enables you to offer supported AMIs, where you charge for software or a service you provide that customers use with their own AMIs.
