  The ALICE experiment is equipped with a wide range of detectors providing
excellent tracking and particle identification in the central region, as well
as forward detectors with extended pseudorapidity coverage, which are well
suited for studying diffractive processes. Cross section measurements of single
and double diffractive processes performed by ALICE in pp collisions at
$\sqrt{s}=0.9,~2.76,~7$~TeV will be reported. Currently, ALICE is studying
double-gap events in pp collisions at $\sqrt{s}=7$~TeV, which give an insight
into the central diffraction processes: current status and future perspectives
will be discussed. The upgrade plans for diffraction studies, further extending
the pseudorapidity acceptance of the ALICE setup for the forthcoming Run 2 of
the LHC, will be outlined.
