<h1><a name="introduction"></a>Introduction</h1>
<p>Every node (server) must have one or more <code>services</code> defined that determines what role the node performs. For example:</p>
<pre><code>workstation$ cat nodes/stallman.json
{
"ip_address": "199.99.99.1",
"services": ["webapp", "tor"]
}
</code></pre>
<p>Here are common questions to ask when adding a new node to your provider:</p>
<ul>
<li><strong>many or few?</strong> Some services benefit from having many nodes, while some services are best run on only one or two nodes.</li>
<li><strong>required or optional?</strong> Some services are required, while others can be left out.</li>
<li><strong>who does the node communicate with?</strong> Some services communicate very heavily with other particular services. Nodes running these services should be close together.</li>
<li><strong>public or private network?</strong> Some services communicate with the public internet, while others only need to communicate with other nodes in the infrastructure.</li>
</ul>
