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> <h1><a name="available-services"></a>Available services</h1> <table class="table table-striped"> <tr> <th>Service</th> <th>VPN</th> <th>Email</th> <th>Notes</th> </tr> <tr> <td>webapp</td> <td><i class="fa fa-circle"></i></td> <td><i class="fa fa-circle"></i></td> <td>User control panel, provider API, and support system.</td> </tr> <tr> <td>couchdb</td> <td><i class="fa fa-circle"></i></td> <td><i class="fa fa-circle"></i></td> <td>Data storage for everything.
