  We construct a large class of non-supersymmetric AdS-like throat geometries
in string theory by taking non-supersymmetric orbifolds of supersymmetric
backgrounds. The scale of SUSY breaking is the AdS radius, and the dual field
theory has explicitly broken supersymmetry. The large hierarchy of energy
scales in these geometries is stable. We establish this by showing that the
dual gauge theories do not have any relevant operators which are singlets under
the global symmetries. When the geometries are embedded in a compact internal
space, a large enough discrete subgroup of the global symmetries can still
survive to prevent any singlet relevant operators from arising. We illustrate
this by embedding one case in a non-supersymmetric orbifold of a Calabi-Yau
manifold. These examples can serve as a starting point for obtaining
Randall-Sundrum models in string theory, and more generally for constructing
composite Higgs or technicolor-like models where strongly coupled dynamics
leads to the breaking of electro-weak symmetry. Towards the end of the paper,
we briefly discuss how bulk gauge fields can be incorporated by introducing
D7-branes in the bulk, and also show how the strongly coupled dynamics can lead
to an emergent weakly coupled gauge theory in the IR with matter fields
including scalars.
