A method of determining component dependencies in an enterprise application architecture implemented over an enterprise network, including identifying structures of hosts connected to the network; wherein the structures includes applications executed by the host, obtaining configuration parameters from said hosts, determining dependencies between applications of hosts based on the configuration parameters, receiving a template for identifying dependencies between components in the enterprise network, identify candidate mappings of hosts based on the template, further identifying candidate mappings of host pairs based on the determined dependencies between hosts and the template, analyzing the candidate mappings to calculate a probability score for the candidate mappings, output the candidate mappings having the highest score.
