1. An apparatus for discovering resources of a distributed computing environment, the apparatus including a computer processor and a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of: identifying, by the management system, a range of IP addresses corresponding to the distributed computing environment; transmitting, by the management system to each IP address of the range of IP addresses corresponding to the distributed computing environment, a series of different types of representational state transfer (REST) application program interface (API) messages corresponding to different types of resources, wherein each of the REST API messages comprises a resource identifier; receiving from one or more of the IP addresses corresponding to the distributed computing environment, by the management system, one or more responses to the series of different types of REST API messages; and based on the responses, determining, by the management system, an identification and type of a resource of the distributed computing environment by examining the responses to identify a particular response that provides information identifying a particular resource.
