The production cross sections of the inclusive Drell-Yan processes W{sup {+-}} {yields} {ell}{nu} and Z/{gamma}* {yields} {ell}{ell} ({ell} = e, {mu}) are measured in proton-proton collisions at {radical}s = 7 TeV with the ATLAS detector. The cross sections are reported integrated over a fiducial kinematic range, extrapolated to the full range, and also evaluated differentially as a function of the W decay lepton pseudorapidity and the Z boson rapidity, respectively. Based on an integrated luminosity of about 35 pb{sup -1} collected in 2010, the precision of these measurements reaches a few percent. The integrated and the differential W{sup {+-}} and Z/{gamma}* cross sections in the e and {mu} channels are combined, and compared with perturbative QCD calculations, based on a number of different parton distribution sets available at next-to-next-to-leading order.
