A rich API access
The Swift proxy process is the only one that can communicate outside a storage cluster, and what it does is listen and speak to a specific REST API.
Thanks to the Swift proxy, we will be able to access the OSDs. On the other hand, Swift provides language-specific libraries for PHP, Java, Python, and so on for ease of integration with applications. The libraries use HTTP calls to speak to the Swift proxy.
An object request always requires an authentication token. Therefore, an authentication can be configured through the WSGI middleware, which is typically keystone.
A complete reference to the object storage APIs can be found at http://developer.openstack.org/api-ref-objectstorage-v1.html.
