W and Z physics with the ATLAS detector

We present measurements involving W and Z bosons production in $pp$ collisions at $sqrt{s}$=7~TeV with an integrated luminosity of $sim$35~pb$^{-1}$ recorded by the ATLAS detector at the Large Hadron Collider. Several analysis is presented: Drell-Yan $ensuremath{W} ightarrow ell u$ and $Zg o ell ell$ ($ell=e,mu$) production cross sections, muon charge asymmetry from W boson, production of jets in association with Zg boson in the final state and di-boson productions ($Wgamma$,$Zgamma$,$W^{+}W^{-}$). The measurements are compared to pertubative QCD predictions with various parton distributions functions.
