  The ALICE experiment at the LHC has measured the production of strange
hadrons and resonances in Pb-Pb and pp collisions at unprecedented high beam
energies. The study of strange hadrons and resonances helps us to understand
the properties of the medium created in the heavy-ion collisions and its
evolution. We present the yields ($dN/dy$) at mid-rapidity for strange hadrons
($\Lambda$, $\Xi^{-}$, $\Omega^{-}$, their anti-particles and $K_{S}^{0}$) and
resonances ($\phi$ and $K^{*0}$) for several collision centrality intervals.
The results from Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV are presented
and compared to corresponding results from pp collisions and lower energy
measurements. Baryon to meson ratios and resonance to non-resonance particle
ratios relative to pp collisions are shown as a function of collision
centrality and compared with the results at lower energies.
