Use OpenStack with Zend Framework 2

OpenStack is becoming the open source standard for cloud computing. Most of the cloud vendors use OpenStack and the community of users is growing every day. In this talk we will give a brief introduction to OpenStack and we will present the new library service for Zend Framework 2 that supports the last version of the OpenStack API. You will see how is easy to use the OpenStack API with ZF2 thanks to a friendly object oriented interface.
This talk has been presented at ZendCon 2013 in Santa Clara (California).

    Status of the project
    ●
    ZendService\OpenStack is a PHP library to
    use the API of OpenStack in a OO fashion
    way
    ●
    The project started in Feb 2013
    ●
    It's 100% compatible with the API
    specifications of OpenStack
    ●
    It uses the ZendService\Api component to
    interact with the HTTP API call
    https://github.com/zendframework/ZendService_Api

    – Compute
    – Identity
    – ObjectStorage
    ●
    We are going to release these others soon:
    – Networking
    – Image

    Under the hood
    ●
    We use ZendService\Api library to
    consume the OpenStack API
    ●
    Simple PHP configuration file to build
    HTTP request. For instance:
    https://github.com/zendframework/ZendService_OpenSta
    ck/blob/master/library/ZendService/OpenStack/api/ide
    ntity/authenticate.php

    services
    ●
    Support API versioning (?)
    ●
