1. A method comprising: based on a resource management request of a first resource management domain, retrieving a set of resource tags from a resource tag database of a second resource management domain based on a key for a resource pool indicated in the resource management request, wherein each of the set of resource tags represents a resource of the resource pool and associates resource identifiers of the first and the second resource management domains that identify the resource represented by the resource tag and wherein naming conventions for identifying resources in the first resource management domain and the second resource management domain are independent; generating a system configuration map based on the set of resource tags, wherein the system configuration map indicates hierarchical configuration relationships among the resources represented by the set of resource tags; comparing the resource management request with the system configuration map to identify a target resource and corresponding target resource information; generating a resource query based on the identified target resource and corresponding target resource information, wherein the resource query specifies a resource identifier assigned to the target resource within one of a plurality of resource management domains that at least includes the first and the second resource management domains; configuring or re-configuring the target resource based, at least in part, on a response to the resource query and the resource management request; and updating the resource tag database based, at least in part, on the configuring or re-configuring of the target resource and the key for the resource pool.
