1. One or more computer storage media having computer-executable instructions embodied thereon that, when executed, perform a method for detecting and alerting of anomalies within a cloud-computing infrastructure, the method comprising: pulling information that describes a state of a plurality of computing devices, respectively, wherein the plurality of computing devices represent nodes within the cloud-computing infrastructure; individually comparing the state information of the plurality of computing devices against one another; based upon the comparison, grouping one or more computer devices of the plurality of computing devices into clusters of nodes that exhibit substantially similar state information; identifying clusters of nodes that include low number of computer devices grouped therein with respect to a remainder of the clusters of nodes; designating the computing devices within the identified clusters of nodes as anomalous machines; and initiating a communication that notifies an administrator of the cloud-computing infrastructure of the anomalous machines.
