Abstract: Embodiments of a method system and computer readable media are provided. In some embodiments, a system for analyzing application environments is provided. The system includes a difference module, residing in at least one computer. The difference module is operable to extract differences between a source environment for an application and a target environment for the application. The system includes a rule-based module, residing in the at least one computer. The rule based module is operable to cooperate with the difference module in applying a plurality of rules to the differences to produce a plurality of weighted differences, each rule of the plurality of rules operable to apply a weight to an environmental difference, the weight quantifying impact, risk, or relevance, of the environmental difference to operability or failure of the application.

Abstract: A method, system and computer-readable media for analyzing application environments is provided. Embodiments of the invention includes generating a first representation of a first environment for an application and a second representation of a second environment for the application. Determining differences between the first representation and the second representation and determining relevance to the application of each of the differences as to a likelihood of failure of operation of the application in the second environment where at least one method operation is executed through a processor.
