1. A method comprising: retrieving logical relationship information regarding a datacenter; generating a layered information model of the logical relationship information regarding the datacenter, the layered information model comprising a directed graph representing physical and logical relationships between a plurality of components of the datacenter, the directed graph comprising a hierarchy of two or more layers representing respective different types of components in the datacenter; and managing the datacenter according to commands received from a datacenter management device configured to navigate the layered information model; wherein managing the datacenter comprises: receiving, at a backend service from the datacenter management device via one or more application programming interfaces, one or more spatial recognition marks for a given component in the datacenter; identifying, at the backend service, a given layer of the directed graph to which the given component belongs using the one or more spatial recognition marks; determining, at the backend service using the layered information model, one or more utilization metrics of the given component; providing, from the backend service to the datacenter management device via the one or more application programming interfaces, the utilization metrics for presentation on a display of the datacenter management device; providing, from the backend service to the datacenter management device via the one or more application programming interfaces, a first user interface feature for navigating across the given layer of the directed graph to view other components of a same type as the given component; and providing, from the backend service to the datacenter management device via the one or more application programming interfaces, at least a second user interface feature for navigating to one or more layers of the directed graph other than the given layer to view one or more components of a different type than the given component that are related to the given component: and wherein providing the utilization metrics for presentation on the display of the datacenter management device comprises providing one or more gauges based on the utilization metrics for overlay on an augmented reality view of at least a portion of the datacenter.
