1. A computing device configured in a computing environment including a plurality of physical resources configured to be employed in providing virtual resources and having an environment sensor outputting sensor data representing changes in an operating property relating to power drawn by a component of a physical resource among the plurality of physical resources, comprising: a processor, coupled to the computing device; the computing device including: a sensor data receptor and a memory configured to receive and store the sensor data output by the environment sensor representing the changes in the operating property relating to the power drawn by the component of the physical resource among the plurality of physical resources; a pattern extractor configured to extract a pattern from the received sensor data from the physical resource among the plurality of physical resources, the pattern representing the changes in the operating property relating to power drawn by the component of the physical resource; a memory storing a list of virtual resources provided by the plurality of physical resources and, for each of the listed virtual resources, an identifier pattern that a listed virtual resource is known to artificially generate in the output sensor data of the physical resource, from among the plurality of physical resources, employed in providing the listed virtual resource; and a pattern matcher configured to compare the extracted pattern with the identifier pattern known to be generated by a virtual resource among the virtual resources, and to identify the physical resource among the plurality of physical resources as providing the virtual resource when a match is found.
