Case Study: Walmart achieves large-scale IT automation and major cost savings with Puppet

Save Money, Live Better: Walmart's Mission Is Enabled by Puppet

Walmart, with a mission to “Save money, live better,” faced the challenge of managing a massive, legacy IT footprint that spans 11,000 stores in 27 countries. By October 2015 the company had automated 49,000 servers and planned to add its Windows fleet to reach 100,000; the core problem was controlling configuration drift and delivering fast, consistent changes across multiple OS platforms and vast geographic distances so stores and logistics teams could operate efficiently.

Walmart selected Puppet Enterprise to automate configuration and deployments, ensuring consistent, repeatable changes across its environment. The result: rollout times dropped from weeks or months to days or hours, automating Oracle DBA users and groups alone saved three weeks per Oracle server build, IT costs and operational friction fell, and engineers gained greater satisfaction from delivering reliable, scalable service to the business.
