  In these lectures I review some recent progresses in counting the number of
microstates of AdS supersymmetric black holes in dimensions equal or greater
than four using holography. The counting is obtained by applying localization
and matrix model techniques to the dual field theory. I cover in details the
case of dyonic AdS$_4$ black holes, corresponding to a twisted compactification
of the dual field theory, and I discuss the state of the art for rotating
AdS$_5$ black holes.
