Abstract: We will review Type II compactifications because of the potential for the construction of realistic MSSM-like compactifications. In particular we concentrate in Type IIB Calabi-Yau orientifolds and its non-perturbative realization: F-theory. These sort of models, have attracted a lot of attention during recent years due to their phenomenological interest. The first part is devoted to an introductory survey of some concepts and aspects of Type II vacua like e.g. the low energy effective action or soft terms. It is also included a brief presentation of F-theory stressing the phenomenological interest of local models. In the second part we present an analysis of the theoretical and phenomenological issues of modulus dominated SUSY breaking. We will see that very simple assumptions about modulus dominance SUSY breaking in F-theory GUTs lead to a predictive set of boundary conditions, consistent with all phenomenological constraints coming from Particle Physics and Cosmology. In addition it will be examined its status in comparison with recent LHC data.
