We review recent progress on holographic renormalization in the
context of the gauge-gravity correspondence when the bulk geometry
is not asymptotically AdS. The prime example is the
Klebanov-Strassler background, whose dual gauge theory has
logarithmically running couplings at all energy scales. The
presented formalism provides the counterterms necessary for
obtaining finite two-point functions of the scalar operators in the
corresponding dual gauge theories. The presentation is
self-contained and reviews all the relevant background material
concerning a gauge-invariant description of the fluctuations around
holographic renormalization group backgrounds.
