1. A method for configuring management data structures of computing resources, the method comprising: mapping a template-level configuration-management data structure to a discovery-level configuration-management data structure by a first mapping using mapping information included in the template-level configuration-management data structure; mapping a customized-level configuration-management data structure to the discovery-level configuration-management data structure by a second mapping using mapping information included in the customized-level configuration-management data structure; and determining a third mapping between the template-level configuration-management data structure and the customized-level configuration-management data structure using the first mapping and the second mapping; managing the configuration-management data structures in a systems-management system and storing the configuration-management data structures to a server system; and wherein the template-level configuration-management data structure has a greatest abstraction level, the discovery-level configuration-management data structure has a lowest abstraction level, and the customized-level configuration-management data structure has an abstraction level between the template-level configuration-management data structure and the discovery-level configuration-management data structure.
