CMS performance, physics, perspectives

During LHC Run-1 (2010-2012) the CMS experiment received almost $30\,\mathrm{fb^{-1}}$ of proton-proton data at the energies of $\sqrt{s} =7$ and 8\,TeV. The accumulated statistics allow CMS to perform frontier measurements at high-energies. In this paper the CMS detector and its performance are briefly described. The highlights of the CMS results are given. Selected Higgs physics results, measurements of vector boson, top-quark and jets production, $\mathrm{B/B_s\rightarrow \mu\mu}$ and searches for new phenomena are described. The CMS upgrade plans are presented, including ongoing activities during present accelerator shutdown as well as modifications in LHC Phase-I and beyond.
