Case Study: Walmart achieves configuration standardization and drift control with Puppet

Walmart manages 48,000+ nodes with Puppet

Walmart, the world's largest retailer, faced the challenge of controlling configuration drift and managing a huge legacy IT environment comprising over 100,000 servers across 11,000 global stores. To standardize change management and empower other engineering teams, the Walmart IT team chose Puppet to tackle this major "brownfield" standardization effort.

Using Puppet, Walmart brought over 48,000 nodes under management, which provided the confidence to make major changes in hours instead of weeks. The solution saved significant time, such as 3 weeks per build when automating DBA user groups. The team at Puppet enabled Walmart to manage drift fantastically well across multiple operating systems and vast geographic distances, ensuring their infrastructure remained available and consistent.
