1. A system for orchestrating composite web services in a constrained data flow environment, said system comprising: a build time module comprising logic circuitry adapted to: receive a composite web service specification; partition said composite web service specification into multiple topologies, wherein each topology comprises a set of composite web service partitions that are communicatively connected with each other at runtime, and wherein each composite web service partition comprises a functionally complete composite web service; and select a topology for deployment; at least one runtime module comprising logic circuitry adapted to verify and deploy partitions of the selected topology within a corresponding component web service domain.
