  Multiorbital systems such as the iron-based superconductors provide a new
avenue to attack the longstanding problem of superconductivity in strongly
correlated systems. In this work we study the superconductivity driven by a
generic bosonic mechanism in a multiorbital model including the full dynamical
electronic correlations induced by the Hubbard U and the Hund's coupling. We
show that superconductivity survives much more in a Hund's metal than in an
ordinary correlated metal with the same degree of correlation. The crucial role
of the redistribution of spectral weight in the Hund's metal reflects also in
the enhancement of the orbital-selective character of the superconducting gaps,
in agreement with experiments in iron-based superconductors.
