In the first part of this paper we provide a short introduction to the AdS/ renormalization. We discuss how QFT correlation encoded in the bulk geometry. In the second part we method of holographic renormalization, with the radial this approach regularized correlation functions are boundary expansions of the standard approach are replaced various terms are organized according to their dilatation expressions for counterterms and one-point functions (in the dimensions. The new approach combines optimally supersedes them in efficiency.
