An approach is provided for backend based computation closure oriented distributed computing. A computational processing support infrastructure receives a request for specifying one or more processes executing on a device for distribution over a computation space. The computational processing support infrastructure also causes, at least in part, serialization of the one or more processes as one or more closure primitives, the one or more closure primitives representing computation closures of the one or more processes. The computational processing support infrastructure further causes, at least in part, distribution of the one or more closure primitives over the computation space based, at least in part, on a cost function.
