Practicing World-Class IT at Walmart with Puppet

Walmart uses Puppet to help fulfill its mission of providing goods to customers at an affordable price. Walmart is currently managing more than 49,000 servers with Puppet, in 11,000 stores located in 27 countries. Before Puppet, it would take four weeks to never to implement changes across its vast infrastructure; now it can take just a couple of days, or in some cases, a couple of hours.
