<title>Get started with OpenStack</title>
<para xml:id="para1">The OpenStack project is an open source cloud
computing platform for all types of clouds, which aims to be
simple to implement, massively scalable, and feature
rich. Developers and cloud computing technologists
from around the world create the OpenStack project.</para>
<para xml:id="para2">
OpenStack provides an Infrastructure-as-a-Service
(<glossterm>IaaS</glossterm>) solution through a set of
interrelated services. Each service offers an application
programming interface (<glossterm>API</glossterm>) that
facilitates this integration. Depending on your needs, you can
install some or all services.

<td>Stores and retrieves arbitrary unstructured
data objects via a <glossterm>RESTful</glossterm>,
HTTP based API. It is highly fault tolerant with
its data replication and scale-out architecture.
Its implementation is not like a file server with
mountable directories. In this case, it writes
objects and files to multiple drives, ensuring the
data is replicated across a server cluster.</td>
