 A _Node_ is a resource that is either a physical or virtual instance of a network accessible host. Nodes have a few basic attributes but a Node's attributes can be extended to include arbitrary named key/value pairs. Each node has a uniquely identifying name. In addition to `name`, some pieces of metadata are required (like `hostname` and `username`) and some are optional. Attributes typically describe the properties of a node or reflect the state of the node. One of a Node's built in attributes is called "tags" which is a list of classifications or categories about that Node.

+When using Ansible inventories, node names must not contain whitespace characters (such as spaces or tabs). Ansible treats whitespace as a separator, which can lead to parsing errors or unexpected behavior if included in node names. To ensure compatibility and avoid issues, always use names without spaces—consider using underscores (_) or hyphens (-) instead. For example, use web_server_01 or db-node-2 rather than web server 01.
