17. One or more non-transitory computer readable media having instructions stored thereon for performing a method of creating a representation of dependency relationships between computing resources within a computing environment, the method comprising: identifying, at a computing device, one or more sources for dependency analysis, each source capable of being accessed to provide computing functionality via the computing environment, each source including one or more references to a respective one or more computing resources, each computing resource defining a unit of the computing functionality available within the computing environment, one or more of the computing resources having an activated state in which the computing functionality defined by the computing resource is available for use and a deactivated state in which the computing functionality defined by the computing resource is not available for use; identifying a plurality of dependency relationships based on the one or more sources, each dependency relationship providing a logical relationship between a respective first one of the computing resources and a second one of the computing resources, wherein the first computing resource can have the activated state only when the second computing resource has the activated state; generating a canonical resource representation of each of the referenced computing resources, the canonical representation allowing different references to the referenced computing resources to be compared for identity; creating a dependency relationship representation based on the identified dependency relationships, the dependency relationship representation comprising a graphical depiction of the identified dependency relationships between the computing resources, wherein creating the dependency relationship representation comprises specifying dependency relationships using the generated canonical resource representations; and displaying the dependency relationship representation on a display device.

The one or more computer readable media recited in claim 17 , wherein the activated or deactivated state of a first computing resource that defines a first unit of the computing functionality differs between a plurality of entities accessing the computing environment, wherein the computing functionality is accessible to a first one of the entities if the first computing resource has an activated state for that entity, and wherein the computing functionality is not accessible to the first entity if the first computing resource has a deactivated state for that entity.
