Zend Framework: Zend_Service_Amazon_DevPay Component Proposal

Table of Contents

1. Overview

DevPay is a new service from Amazon that provides both a UI-driven subscription and billing interface paired with a product activation and licensing web service. According to Amazon:

Amazon DevPay allows you to use Amazon's infrastructure to manage customer subscriptions and billing for your Amazon EC2 Machine Images (AMIs) or applications that use Amazon S3. To use Amazon DevPay, you simply:

• Develop your software application using Amazon S3 or an Amazon EC2 Machine Image (AMI).
• Use the simple Amazon DevPay web interface to register your application or AMI with Amazon DevPay, provide a product description and configure your desired pricing.
• Embed the Amazon DevPay purchase pipeline link into your web site to allow your customers to purchase your product.
• Integrate with Amazon DevPay's authentication mechanism to ensure that only authorized users access your application.
• Monitor your business on the Amazon DevPay Activity page.

This API has been designed to accommodate new APIs and support for additional AWS services in the future.

4. Dependencies on Other Framework Components

• Zend_Exception
• Zend_Http
• Zend_Service_Amazon_Authentication

5. Theory of Operation

Zend_Service_Amazon_DevPay is instantiated directly using the credentials supplied by the developer. All operations can then be called from this object. All errors are wrapped in a Zend_Service_Amazon_Exception instance. All errors are passed through, except in cases where the client is advised to retry the request. If the retries fail, these errors are also wrapped in an instance of Zend_Service_Amazon_Exception and thrown to the user.
