14. A system for selection of a runtime stack for deployment of a Web Service, comprising: a runtime container comprising a processor and a plurality of stacks to which a Web Service could be deployed; a generator that generates policy assertions for a Web Service to be deployed; a scoring mechanism applied to the policy assertions for the Web Service to be deployed that is dynamically unique for each available runtime stack in which the ability of a stack to support each of a plurality of policy assertions is scored with a numerical value; and a selector for selecting a stack based on the results of applying the scoring mechanism dynamically unique for each available runtime stack.
