Progress in Computing

In the light of the experiences of the first few months with LHC data, the progress in building the grid infrastructure is reviewed, describing the programme of testing that was essential for creating a working grid. Some of the key achievements of the experiments are noted, particularly the remarkable success of producing physics results within weeks, as highlighted in this conference. Building on some of the lessons learned in the preparation phase as well as early experience with data, the outlook for evolution of the infrastructure in the future is described.
