Systems, methodologies, media, and other embodiments associated with key-configured topology connection management are described. One exemplary system embodiment includes a logic for mapping a resource to a port through which it can be accessed and a logic for determining whether a requestor will be granted a connection to the machine on which the resource resides based, at least in part, on membership in a key-configured topology. Membership in the key-configured topology may be determined by a connection management logic analyzing a key provided by the requestor in a request related to accessing the resource. The key may be internally generated by a key maintenance logic.
