A discovery application may obtain, from a remote storage system configured to host storage structures, first data that identifies relationships among the storage structures. The discovery application may generate, based on the first data, a mapping of the storage structures, store the mapping as one or more configuration items, and provide, to the remote storage system, instructions configured to cause the remote storage system to notify the discovery application of modification events associated with the storage structures. The discovery application may receive, from the remote storage system, a notification of a modification event associated with a particular storage structure of the storage structures and, in response, obtain, from the remote storage system, second data that identifies a modification to the particular storage structure. The discovery application may modify the mapping based on the second data and store the modified mapping by updating the one or more configuration items.
