1. A method of implementing deployment pattern matching within models of computing environment, comprising: accessing a target computing environment model that electronically captures environment modeling parameters relating to resources and resource-resource relationships of a corresponding computing environment; expressing the target computing environment model as a model graph defined by target resource elements and resource-to-resource relationship links; accessing a realization pattern that electronically captures deployment parameters relating to resources and resource-resource relationships of a deployment of interest; expressing the realization pattern as a pattern graph defined by conceptual resource elements and constraints arranged by resource-to-resource relationship links and constraint links; utilizing a processing device to evaluate the realization pattern against the target computing environment model by executing at least one pattern matching algorithm that attempts to match the pattern graph to the model graph; and conveying information corresponding to results of the evaluation.
