  <title>Install and configure the controller node</title>
  <para>This section describes how to install and configure the proxy
    service that handles requests for the account, container, and object
    services operating on the storage nodes. For simplicity, this
    guide installs and configures the proxy service on the controller node.
    However, you can run the proxy service on any node with network
    connectivity to the storage nodes. Additionally, you can install and
    configure the proxy service on multiple nodes to increase performance
    and redundancy. For more information, see the
    <link xlink:href="http://docs.openstack.org/developer/swift/deployment_guide.html"
    >Deployment Guide</link>.</para>
  <procedure>
    <title>To configure prerequisites</title>
    <para>The proxy service relies on an authentication and authorization
      mechanism such as the Identity service. However, unlike other services,
      it also offers an internal mechanism that allows it to operate without
      any other OpenStack services. However, for simplicity, this guide
      references the Identity service in <xref linkend="ch_keystone"/>. Before
      you configure the Object Storage service, you must create service
      credentials and an API endpoint.</para>
    <note>
      <para>The Object Storage service does not use a SQL database on
        the controller node. Instead, it uses distributed SQLite databases
        on each storage node.</para>
