Example implementations relate to configuring a managed device. For example, configuration of a managed device may be performed by a services controller. The services controller may comprise a processing resource and a memory resource storing machine readable instructions to cause the processing resource to perform a number of actions. For instance, the services controller may manage configuration of a network using a hierarchical configuration model. The services controller may define a plurality of configuration elements for each of a plurality of managed devices in the hierarchical configuration model, where configuration elements shared among the plurality of managed devices are assigned a same setting from the services controller, and the configuration elements assigned by the services controller are customizable by each of the plurality of managed devices.
