  The AdS/CFT correspondence is a powerful tool to study the properties of
conformal QCD at strong coupling in terms of a higher dimensional dual gravity
theory. The power-law falloff of scattering amplitudes in the non-perturbative
regime and calculable hadron spectra follow from holographic models dual to QCD
with conformal behavior at short distances and confinement at large distances.
String modes and fluctuations about the AdS background are identified with QCD
degrees of freedom and orbital excitations at the AdS boundary limit. A
description of form factors in space and time-like regions and the behavior of
light-front wave functions can also be understood in terms of a dual gravity
description in the interior of AdS.
