A technique maintains configurations of an intermediate node in a version control system. Entities within the intermediate node are represented by objects. Each object is associated with a state. Each object is distinct from other objects in the intermediate node, thus enabling the state of an object to be changed, without affecting other objects. Versions of the objects' states are maintained in the version control system. The version control system is configured to maintain one or more versions of state associated with the objects. A configuration of the intermediate node is defined by labeling a version of objects saved in the version control system. A configuration is applied to the intermediate node by acquiring the states of objects associated with the configuration from the version control system and configuring the intermediate node's entities represented by the objects in accordance with the acquired states.
