In this talk we discuss several aspects of the description of QCD at high center of mass energies. After a brief review of reggeization of the gluon and the BFKL-equation, we turn to heavy flavor production in hadron-hadron collisions within kT factorization, using NLO unintegrated gluon densities. In a second part we discuss the gauge invariant effective action of high energy QCD, proposed by L.N. Lipatov. We present a set of rules that allow for a rederivation of gluon reggeization and the BFKL-equation from the effective action. These rules are then used to derrive transition vertices of QCD Reggeon field theory and a comparision of our results with earlier studies is given.
