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