Introduction

This document contains the design specifications for gCloud, a Google Compute Engine(GCE) like API front end For Apache Cloudstack.

Purpose

gCloud supplies a layer ontop of the Apache Cloudstack API. The purpose of this layer is to expose a Google Compute Engine(GCE) like API for Cloudstack.

gCloud will accept GCE based API calls, translate and pass them over to the Apache Cloudstack API, parse the response and return it in a suitable GCE format.

Design

gCloud is a Python application that uses Flask. It exposes a Google Compute Engine(GCE) complaint API.

Authentication

Google compute engine uses OAuth2 for authentication. As Apache Cloudstack does not expose an OAuth2 Provider it was necessary to create a make-do work around for this.
