A method comprises building a registry of available discovery adapters, obtaining discovery data from information technology infrastructure, generating a discovery plan comprising a list of discovery adapters by matching one or more information technology resource types identified in the discovery data to information technology resource types associated with respective ones of the available discovery adapters, providing the discovery data to the discovery adapters in the list to execute a discovery run comprising the discovery adapters analyzing the discovery data and storing information on information technology resources in a discovered resources repository, and dynamically adjusting allocation of the information technology resources based on the information stored in the discovered resources repository.
