  The holographic light-front QCD framework provides a unified nonperturbative
description of the hadron mass spectrum, form factors and quark distributions.
In this article we extend holographic QCD in order to describe the gluonic
distribution in both the proton and pion from the coupling of the metric
fluctuations induced by the spin-two Pomeron with the energy momentum tensor in
anti--de Sitter space, together with constraints imposed by the Veneziano
model{\color{blue},} without additional free parameters. The gluonic and quark
distributions are shown to have significantly different effective QCD scales.
